Biodiesel derived from renewable plant sources is monoalkyl esters of long chain fatty acids which fall in the carbon range C12-C22. It has similar properties as mineral diesel. Various processes exist to convert vegetable oils (mainly triglycerides) into biodiesel. Transesterification of vegetable oils using alcohol in a catalytic environment is most commonly used method for producing biodiese...

H Biodiesel has received much attention in recent years. Although numerous reports are available on the production of biodiesel from vegetable oils of terraneous oil-plants, such as soybean, sunflower and palm oils, the production of biodiese...

Crude glycerol is the byproduct of biodiesel production plant and the economic value of glycerol may affect the profitability of the biodiesel production plant. As the production rate of bioglycerol increases, its market values drop considerably. Therefore, conversion of bioglycerol into value-added products can reduce the overall cost, hence, leading to a more economical biodiesel production p...

The yeast Yarrowia lipolytica accumulates oils and is able to produce extracellular lipases when growing in different carbon sources including glycerol, the principal by-product of the biodiesel industry. In this study, biomass production of a novel mutant strain of Y. lipolytica was statistically optimized by Response Surface Methodology in media containing biodiesel-derived glycerol as main c...

this paper mainly focuses the study and analysis of the existing contributions related to the biodiesel production. it, firstly, discuss the key issues related contributions which include chemical process, reactor designing, plantation, blending and applications. next, it summarizes the analysis of the other prominent contributions related to process model, design, production, cost, optimizatio...

BACKGROUND Single cell oils (SCOs) accumulated by oleaginous fungi have emerged as a potential alternative feedstock for biodiesel production. Though fungi from mangrove ecosystem have been reported for production of several lignocellulolytic enzymes, they remain unexplored for their SCO producing ability. Thus, these oleaginous fungi from the mangrove ecosystem could be suitable candidates for...

the aims of this study were to assess the energy and economic flows of biodiesel production from olive pomace oil using transesterification method with ultrasound waves. for this purpose biodiesel production from this feedstock were examined through a life-cycle process with considering five main stages of agricultural production, transportation, olive oil extraction, pomace oil extraction and ...

although in mexico the cases and the experiences in bioenergy production are limited, at a worldwide level the knowledge in this area has grown up significantly. for example, unlike argentina and brazil, mexico has only recently begun its bioenergy production from agricultural crops. so this paper will present a review of the actual conditions encountered in mexico as far as biofuels production...
