Using biodiesel fuel to reduce emissions from diesel engines is an area of increasing interest. Many environmental … benefits associated with biodiesel are not traded in markets and their estimation requires economic valuation methods applied … two Ohio regions to estimate willingness to pay for air pollution reduction arising from using biodiesel fuel in diesel …

associated with the production and use of biodiesel fuels from soybean feedstock. Applying a framework that couples life cycle … and biodiesel's external damages. The results of the study reveal that production and consumption of soybean based …

This work investigated the potential of shea butter oil (SBO) as feedstock for synthesis of biodiesel. Due to high free … while its conversion to biodiesel was modeled and optimized using RSM and artificial neural network (ANN). The acid value of …/v, oil/methanol molar ratio of 3.5, and time of 30 min with actual shea butter oil biodiesel (SBOB) yield of 99.65% (w …

research into alternative energy sources such as biofuels. Biodiesel has attracted considerable attention in recent years as an … alternative to fossil fuels, since it is renewable, biodegradable and non-toxic. Biodiesel can be obtained from animal fat …, vegetable oils including cooking oil. In this work, a method of producing biodiesel from seed cake waste from the edible …

Due to rapid depletion of the fossil fuel reserves and environmental concerns biodiesel has attracted a great deal of … the transesterification reaction of waste cooking oil for biodiesel production. The physicochemical properties of the … catalytic activity in the transesterification of WCO, providing maximum biodiesel yield of 89.33% at 5.0 g of catalyst loading …

The production of biodiesel from waste palm cooking oil using acidic ionic liquid as a catalyst was investigated …-methyl imidazolium hydrogensulfate (BMIMHSO4) was found to be effective due to its longer side chain. The highest biodiesel Yield was …, 1.0 wt.% and 60 min of reaction time. The final yield was 95.65 wt.%. The synthesized biodiesel was analysed by 1H NMR …
