Bleaching of crude glycerol by organobentonite

2010
As an alternative to fossil fuel, production of biodiesel is very attractive but limited supply of raw materials, capital and production costs make the process less economically feasible. Because the process economics is improved by the supplementary utilization of glycerole, refinery of the crude glycerole is of importance even it means the additional

Polyols and polyurethane foams from base-catalyzed liquefaction of lignocellulosic biomass by crude glycerol: Effects of crude glycerol impurities

Industrial Crops and Products, 2014
Abstract This study investigated the effects of organic impurities in crude glycerol, including free fatty acids (FFAs), methyl esters of fatty acids (FAMEs), and glycerides, on the properties of polyols and PU foams derived from crude glycerol-based liquefaction of lignocellulosic biomass catalyzed by a base.

Valorization of crude glycerol by microorganisms: A bibliographic and technological survey

Marine Pollution Bulletin
The objective of this review was to investigate the current state of the development of biotechnological routes for the valorization of crude glycerol (CG) using microorganisms, through patent documents and scientific articles. The patents and articles were retrieved through combinations of the code C12N (microorganisms or enzymes), microalgae, and the
