ACC - 2019 International Conference on Applied Catalysis and Chemical Engineering April 08-10, 2019 Venue Crowne Plaza by Deira Salahuddin Rd-Dubai United Arab Emirates Publishing Partner DAY 1 MONDAY, April 08, 2019 Keynote Presentation Towards an Industrial Production of Hydrogen Through Catalytic Autothermal POX/Dry Reforming of Methane Jnicolas Abatzoglou *, Frank Dega and Mostafa Chamoumi Université de Sherbrooke, Sherbrooke, Canada Abstract The diversification of energy sources, especially using non-fossil resources, is an efficient way to contribute to the solution of both environmental and socio-political issues. Hydrogen produced from renewable sources, such as biomass, appears as one of the potential future energy and raw material vectors. Currently, H 2 is mainly produced through natural gas and biogas catalytic steam reforming. This work belongs to a larger endeavour aimed at developing a new family of spinel-based catalysts. More specifically, this study targets the optimization of hydrogen production through a POX/Dry reforming of methane, operated close to the autothermal regime. The used patent-pending catalyst is a spinellized nickel formulation prepared from an ilmenite- derived negative value upgraded slag oxide (UGSO) coming from a TiO2 slag production unit operated by Rio Tinto Iron & Titanium, Quebec, Canada. The initial tests have been done in a tubular fixed bed reactor at 800-850°C, m cat = 0,3g, atmospheric pressure, space velocity between 4000 and 4600 ml STP /h/g cat and molar ratio of CH4 /CO2 = 3. The experiments revealed that CH4 /O2 = 2 molar ratio is the optimum condition, at 850°C. At these conditions, the conversion of CH 4 and CO reached 99% and 65% respectively while the selectivity of H 2 and CO was 104% and 79% respectively. An endeavour to evaluate the proposed process at kg-lab scale (3 000 times bigger than the g-lab tests) is underway. A reactor, able to be operated at pressures up to 30 atm and temperature of 850°C, has been built and the data will be available to be presented in the conference.

Oxidative Dehydrogenation of Propane (ODH) into Propylene on Metal-Containing Zeolite Catalytic Systems Stanislaw Dzwigaj Sorbonne University, France Abstract The transition metals well dispersed at zeolite framework are considered to be active sites of catalytic processes. Therefore, the incorporation of these metals into the microporous zeolite materials as isolated 03 ACC-2019 I APRIL 08-10, 2019 I DUBAI, UAE tetrahedral sites appears to be the important task. We have earlier shown that the incorporation of transition metal ions into vacant T-atom sites of framework zeolite is strongly favored when, in the first step, zeolite is dealuminated by treatment with nitric acid solution and then, in the second step, the incorporation of transition metal ions in zeolite framework results in the reaction between the cationic metal species of the precursor solution and the SiO-H groups of vacant T-atom sites created by dealumination of zeolite. During the plenary talk the design of new single-site zeolite catalysts with transition metal species (V, Cr, Co) will be described and characterized by different physico-chemical techniques both at the macroscopic (chemical analysis, XRD, BET, thermal methods (TPR, TPO, TPD), TEM) and molecular levels (FT-IR, NMR, diffuse reflectance UV-Vis, XPS, EPR, XAFS). The application of metal-single site zeolite catalysts in oxidative dehydrogenation (ODH) of propane into propene will be discussed. The two-step postsynthesis method applied in this work allowed obtaining single sites V-, Cr- and Co-containing zeolite catalysts with isolated mononuclear metal species active in ODH process. Their catalytic activity strongly depends on the speciation and amount of metal incorporated into zeolite structure. Biography Stanislaw Dzwigaj was trained in chemistry in Institute of Catalysis and Surface Chemistry, Krakow (Poland) where he obtained his PhD in Science in 1982 in the group of Prof. Jerzy Haber. After a postdoctoral stay at the Laboratoire de Réactivité de Surface Université P. et M. Curie (Paris, France) in the group of Dr Denis Barthomeuf (1987-1988) he obtained in 1990 a position of contract researcher in the same Laboratory devoted to surface reactivity in relation to catalysis phenomena. Then, in 2008 he obtained permanent position in CNRS as a researcher. On February 19, 2014 for outstanding scientific achievements he received the title of professor. Predictive Heterogeneous Catalysis by Design: Well-Defined Single-Site Catalysts J-M Basset KAUST Catalysis Center, Saudi Arabia Abstract "Predictive catalysis" or "catalysis by design" in heterogeneous catalysis has recently benefited from using "surface organometallic fragments" (SOMF) or Surface Coordination fragments (SCF) to enter any presumed catalytic cycle. These conceptual tools in which one or several fragments of the molecule are linked to metal grafted on the surface (M-H, M-R, M=CR2, M?CR, M=O, M=NR) became the logical continuation of the abundant work published in the field of Surface Organometallic Chemistry (SOMC). To note, SOMC has produced new catalytic reactions (e.g. Ziegler Natta depolymerisation, alkane metathesis, non-oxidative methane coupling etc...) and had improved the activity or selectivity or life time of known ones. The catalytic mechanisms employs the concepts of molecular chemistry (organic, organometallic, coordination chemistry) to explain how bonds can be broken and reformed. In this context, the reactivity of "surface organometallic fragments" (SOMF) or Surface Coordination fragments (SCF) is pivotal to the outcome of the catalysis. Both types of fragments were identified within SOMC as it allows the isolation of single-site well- defined heterogeneous catalyst. SOMC can generate catalytic sites that are in principle identical (single-site or single atom) by grafting transition metal atoms onto highly dehydroxylated metal oxide support handled under controlled atmosphere. This strategy presents considerable advantages over traditional heterogeneous catalysts in which various populations of metallic potentially active sites coexist. In this framework, all the steps of the preparation are carefully controlled with the concepts and tools of organometallic and/or coordination chemistry. Hence, the coordination sphere of the grafted metal can be determined with a high degree of accuracy (well-defined catalytic site) by the modern solid characterization tools (Surface Microanalysis, in situ IR, in situ UV, in situ solid state NMR, EXAFS and in operando EXAFS, etc... ). It means that all atoms coordinated to the metal or in its close vicinity are identified. Another benefits came from the surface to be considered as a rigid ligand, preventing in most cases undesired interferences between the 04 ACC-2019 I APRIL 08-10, 2019 I DUBAI, UAE catalytic sites (e.g. by bimolecular deactivation in homogeneous catalysis). Within this framework, the relationship between structure and activity become possible; with the addition of the SOMF tools, it becomes predictable. It is now possible to follow the various steps of the catalytic cycle, understand deactivation, increase activity and/or selectivity by changing the support or ligand environment of the active site. The existing gap which was existing between heterogeneous catalysis and homogeneous catalysis has completely disappeared and a new domain is emerging. We shall review here some of the recent catalytic results obtained on oxides. References Pelletier, J. D. A.; Basset, J.-M. Acc. Chem. Res. 2016, 49 (4), 664-677 and references therein Ibidem, Chem.
