However, petroleum, carbon and natural gas have a finite character and its direct impact on the global warming by the emissions of greenhouse gases and other environmental issues is well known. Hence, the search and development of sustainable and renewable production routes of fuels and materials is mandatory. Biomass has been proposed as the most interesting alternative feedstock due to its renewable character and its potential for producing derived materials and fuels. This research work is focused on the production of biobased materials by environmentally friendly processes using mainly vegetable oils as raw material. Biopolyols and biolubricants are the main targets because of its great consumption and the low biodegradability and high environmental impact of their non-renewable petroleum-based homologous. In order to promote a versatile and economically interesting full process, the research started up with the transformation of two different vegetable oils (namely grape seed and high-oleic sunflower oil) into platform chemicals which would be used in subsequent steps. Firstly, grape seed oil was successfully epoxidized in presence of peracetic acid generated in situ. The obtained kinetic model indicated that moderate high temperatures (90 ºC) and short reaction times (1 h) are the optimal to minimize the effect of secondary reactions. Secondly, the viability of using DBSA as amphiphilic catalyst during the acid hydrolysis of vegetable oils was tested. The effect of temperature, reaction time and the concentrations of DBSA and water was determined through the experimental design technique. The results from the ANOVA test indicated the great influence of the temperature on the fatty acid content of the product. On the other hand, the influence of time was predicted to be almost negligible. Once that the platform chemicals were successfully obtained, the transformation into high added value products was studied. Firstly, the viability of the ring-opening reaction of oxirane groups contained in epoxidized grape seed oil to produce biopolyols was studied. In a first approach, NaN3 was used as ring-opening reagent, finding a covalent linkage among the azide group and the biopolyol. In this case, the Table of contents obtention of a rigid polyurethane foam using exclusively the azidified polyol was possible, achieving a significant improvement of the thermal stability of the foam. In a second approach, H3PO4 was used as ring-opening agent. Similar to NaN3, the covalent linkage of phosphate groups was demonstrated by FTIR and 31P-RMN. Unfortunately, the obtention of polyurethane foams using exclusively the phosphorylated polyol was not possible and uniquely a 57 wt.% was successfully incorporated into the formulation. Finally, thermogravimetric and surface composition analyses revealed the formation of a phosphoro-carbonaceous protective layer. Respecting to the production of biolubricants, free fatty acids were used as main raw material on its synthesis through two different processes.

The conceptual design of the reactive separation process is based on the element concept where the reactive driving force approach is employed. To validate the proposed design, steady state simulations using ASPEN PLUS® software package were accomplished, and a sensitivity analysis was done to establish the operating conditions of the process. The analysed parameters were as follows: i) the operating pressure and ii) the reflux ratio. The results showed that a new energy-efficient design with minimal energy requirements may be considered a viable technological alternative for ethanol synthesis. Also, this reaction-separation process allows to satisfy the design and operating constrains. This is, a novel reactive distillation process capable to increase the purity of the ethanol from a dilute solution, i.e., up to 30% ethanol in water under optimal operating conditions.

The process is also known as catalytic distillation when a solid catalyst is used. RD technology has many key advantages such as reduced capital investment and significant energy savings, as it can surpass equilibrium limitations, simplify complex processes, increase product selectivity and improve the separation efficiency. But RD is also constrained by thermodynamic requirements (related to volatility differences and heat of reaction), overlapping of the reaction and distillation operating conditions, and the availability of catalysts that are active, selective and with sufficient longevity. This paper is the first to provide insights into novel reactive distillation technologies that combine RD principles with other intensified distillation technologies – e.g. dividing-wall columns, cyclic distillation, HiGee distillation, and heat integrated distillation column – potentially leading to new processes and applications. 1. Introduction Reactive distillation (RD) is one of the best success stories of process intensification technology – developed since the early 1920s – that made a strong positive impact in the chemical process industry (CPI).

  • Entrainer-Enhanced Reactive Distillation
    ENTRAINER-ENHANCED REACTIVE DISTILLATION Alexandre C. DIMIAN, Florin OMOTA and Alfred BLIEK Department of Chemical Engineering, University of Amsterdam, Nieuwe Achtergracht 166, 1018 WV Amsterdam, The Netherlands Correspondent: [email protected] ABSTRACT The paper presents the use of a Mass Separation Agent (entrainer) in reactive distillation processes. This can help to overcome limitations due to distillation boundaries, and in the same time increase the degrees of freedom in design. The catalytic esterification of fatty acids with light alcohols C2-C4 is studied as application example. Because the alcohol and water distillate in top simultaneously, another separation is needed to recover and recycle the alcohol. The problem can be solved elegantly by means of an entrainer that can form a minimum boiling ternary heterogeneous azeotrope. Water can be removed quantitatively by decanting, or by an additional simple stripping column. The use of entrainer has beneficial effect on the reaction rate, by increasing the amount of alcohol recycled to the reaction space. The paper discusses in more detail the design of a process for the esterification of the lauric acid with 1-propanol. The following aspects are investigated: chemical and phase equilibrium, entrainer selection, kinetic design, and optimisation. Minimum and maximum solvent ratio has been identified. A significant reduction of the amount of catalyst can be obtained compared with the situation without entrainer. INTRODUCTION Reactive Distillation (RD) is considered a promising technique for innovative processes, because the reaction and separation could be brought together in the same equipment, with significant saving in equipment and operation costs. However, ensuring compatibility between reaction and separation conditions is problematic.

Operating in batch mode, in either tray or packed columns, offers the flexibihty required by pharmaceutical and hne chemical industries for producing low volume/high value products with varying specifications. However, regular packed or tray columns may not be suitable for high vacuum operations due to the pressure drop across the column section and short path distillation may be more applicable. The objective of this thesis is to investigate the control of reactive distillation in batch columns, tray and packed, and in short path columns.

To achieve the work, Aspen HYSYS model of the process was first developed and simulated to obtain the data used to formulate the transfer function model of the process. The transfer function model was tested for stability, which was ascertained from the attainment of steady state by the output of the process, through simulation and, later, run using random number to generate the data required for the development of ARX and ARMAX models of the process that were also simulated and their performances compared. The results obtained revealed that the developed ARX and ARMAX models had moderate orders. Also, good agreements were found to exist between the measured mole fraction of bottom cis-2-hexene and the simulated ones, implying that the developed models were good representatives of the process. Moreover, the lower mean of squared error value and the higher fit value of the developed ARMAX model revealed that it was able to represent the process better than the developed ARX model.

  • Novel Catalytic Reactive Distillation Processes for a Sustainable Chemical Industry
    Topics in Catalysis https://doi.org/10.1007/s11244-018-1052-9 ORIGINAL PAPER Novel Catalytic Reactive Distillation Processes for a Sustainable Chemical Industry Anton A. Kiss1,2 © The Author(s) 2018 Abstract Reactive distillation (RD) is a great process intensification concept taking advantage of the synergy created when combin- ing (catalyzed) reaction and separation into a single unit, which allows the concurrent production and removal of products. This feat improves the productivity and selectivity, reduces the energy usage, eliminates the need for solvents, and leads to highly-efficient systems with improved sustainability metrics (e.g. less waste and emissions). This paper provides an over- view of the key features of RD processes, with emphasis on novel catalytic/reactive distillation processes that can make a difference at large scale and pave the way for a more sustainable chemical process industry that is more profitable, safer and less polluting. These examples include the production of: acrylic and methacrylic monomers, unsaturated polyesters resins, di-alkyl ethers, fatty esters, as well as other short alkyl esters (e.g. by enzymatic reactive distillation). The main drivers for such new RD applications are: economical (large reduction of costs and energy use), environmental (lower CO 2 emissions, no or reduced waste) and social (improved safety and health due to lower reactive content, reduced footprint and run away sensitivity). Hence RD technology strongly contributes to all three pillars of sustainability in the chemical process industry. Nonetheless, the potential of RD technology has not been fully tapped yet, and there is still undergoing research to improve it further by various means: e.g.
