India *Email: [email protected] Phone: +919424747687 ABSTRACT In the present study, the performance of a new combination of biofuels jatropha biodiesel and turpentine oil for a diesel engine with a view to eliminate dependency on fossil fuel was observed. Jatropha biodiesel and turpentine oil are a high and low viscosity fuel combination with comparable heating values to that of diesel; this makes them conducive for in a diesel engine. The extensive experimental work was carried out on a Kirloskar make-single cylinder, constant speed, four strokes, 661cc diesel engine to examine the combustion performance and emission characteristics using the jatropha methyl-ester with turpentine oil and pure diesel. The engine was fuelled with the jatropha methyl-ester with turpentine oil (50% - 50% on a volume basis) blend run on different loading conditions from no load, 35%, 65%, and full load. The blend of a dual biofuel was prepared with the help of a magnetic stirrer at 40°C in the presence of a surfactant span 80. The dual fuel blend was found to be superior to the diesel fuel in all aspects such as performance and emissions.

The study Accepted 17 April 2011 indicates that while second generation biofuels could significantly contribute to the future energy supply mix, cost is a major barrier to its commercial production in the near to medium term. Depending Keywords: upon type of biofuels, feedstock prices and conversion costs, the cost of cellulosic ethanol is found to be Bioenergy two to three times higher than the current price of gasoline on an energy equivalent basis. The median Energy crops cost (across the studies reviewed) of biodiesel produced from microalgae, a prospective feedstock, is Renewable energy seven times higher than the current price of diesel, although much higher cost estimates have been reported. As compared with the case of first generation biofuels, in which feedstock can account for over two-thirds of the total costs, the share of feedstock in the total costs is relatively lower (30–50%) in the case of second generation biofuels. While significant cost reductions are needed for both types of second generation biofuels, the critical barriers are at different steps of the production process.

Russell Cross August 2017 Major Subject: Animal Science Copyright 2017 Vinicius Papin Briani ABSTRACT Effects of increasing levels of the anti-nutritional compounds karanjin and pongamol on intake, nutrient utilization and ruminal fermentation were evaluated with a growing diet (trial I) and a forage diet (trial II). Steers had ad libitum access to growing diet and Bermuda grass hay during trial 1 and trial 2, respectively. At the same time diets were fed, steers received their allocated doses of karanjin and pongamol via ruminal cannula to determine acceptable inclusion level of pongamia seedcakes containing varying levels of karanjin and pongamol, which are contained in the residual oil of commercially available pongamia seedcakes. Twelve steers in both studies were assigned to completely randomized block design consisting of a control (no karanjin and no pongamol) and one of 3 levels of karanjin and pongamol. Dosing increasing levels karanjin and pongamol linearly (P < 0.01) decreased intake in Trial 1. No significant effects (P ≥ 0.12) were observed for total DMD, OMD, NDFD, ADFD and CPD.

Turn, and William Kusch Cite This: https://doi.org/10.1021/acsomega.1c00635 Read Online ACCESS Metrics & More Article Recommendations *sı Supporting Information ABSTRACT: Pongamia, a leguminous, oilseed-bearing tree, is a potential resource for renewable fuels in general and sustainable aviation fuel in particular. The present work characterizes physicochemical properties of reproductive materials (seeds and pods) from pongamia trees grown in different environments at five locations on the island of Oahu, Hawaii, USA. Proximate and ultimate analyses, heating value, and elemental composition of the seeds, pods, and de-oiled seed cake were determined. The oil content of the seeds and the properties of the oil were determined using American Society for Testing and Materials and American Oil Chemist’s Society methods. The seed oil content ranged from 19 to 33 wt % across the trees and locations. Oleic (C18:1) was the fatty acid present in the greatest abundance (47 to 60 wt %), and unsaturated fatty acids accounted for 77 to 83 wt % of the oil. Pongamia oil was found to have similar characteristics as other plant seed oils (canola and jatropha) and would be expected to be well suited for hydroprocessed production of sustainable aviation fuel. Nitrogen- containing species is retained in the solid phase during oil extraction, and the de-oiled seed cake exhibited enrichment in the N content, ∼5 to 6%, in comparison with the parent seed. The pods would need further treatment before being used as fuel for combustion or gasification owing to the high potassium and chlorine contents.

The process parameters including the reaction time, reaction temperature, acidic concentration, base concentration and methanol to oil molar ratio were varied within the specified range to obtain maximum biodiesel yield. Methanol to oil molar ratio 7:1, reaction time 60 minutes, reaction temperature 70oC and catalyst concentration of 0.25% yielded 96% of biodiesel. Design of experiments based on four factor three level (L9) orthogonal array of Taguchi approach reduced the number of iterations from 81 to 9 in identifying the stable emulsified formulation of biodiesel, diesel and water with surfactant. Sample number 8 viz., D75-PBD20-W5-S6 emulsified fuel blend was found to be stable for more than fourteen days. Based on this Taguchi method, number of experiments and duration was significantly reduced in identifying the stable emulsified fuel blend which can be tested further in CI engine.

[email protected]; [email protected]; [email protected] ABSTRACT The pollution caused by fuel combustion either for mechanical or electrical energy generation purposes is nowadays one of the most important environmental issues. It has been proven that combustion emissions, particularly those from cars and trucks, are linked with severe damages to the environment and human health. Along with the environmental problems, is necessary to consider that fossil resources are declining and their exploitation is getting more and more expensive. Bioenergy represent a sustainable solution for energy generation. Bioenergy is renewable energy made from plant‐derived organic matter, collectively termed "biomass". Biomass‐based energy sources are potentially carbon dioxide neutral and recycle the same carbon atoms. Life cycle assessments are reported to evaluate the net environmental impacts of biofuels. The term biofuel refers to liquid or gaseous fuels for the internal combustion engines that are predominantly produced from biomass. Biofuel policy might capitalize on the production of biofuels supporting rural economic development and sustainable agriculture. Amongst biofuels pure plant oil (PPO) has been investigated. This paper sets out to review the state of the art for PPO use as fuel in diesel engines, based on a wide literature review.

However, the full medicinal potential of many seed oil plants is yet to be properly reviewed, particularly for their antimicrobial and antioxidant properties. North-East India has rich resources of seed oil plants. The availability of detailed information on these plants is quite limited. This review aims to explore and evaluate these seed oil plants of the North-East India with particular emphasis on their antimicrobial and antioxidant activities as well as chemical compositions. A comprehensive literature search on seed oil plants of this region has been performed. Seed oil yielding plants of this region can be categorized into two categories: plants that are used traditionally as sources of edible or medicinal oils and plants that are used for purposes other than as sources of oils. Many seed oil plants of this region have been reported to possess antimicrobial and antioxidant properties, and to produce various types of compounds.
