Viable Glycerol Carbonate Synthesis Through Direct Crude Glycerol Utilization from Biodiesel Industry

Waste and Biomass Valorization, 2016
Synthesis of organic carbonates specifically glycerol carbonate has become a major concern among researchers due to its interesting chemical properties. In this study, we report the direct utilization of two different sources of crude glycerol in glycerolysis reaction with urea for the synthesis of glycerol carbonate using potassium silicate containing

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.

The Sustainable Production of Polyhydroxyalkanoates from Crude Glycerol

2020
This chapter focuses on the use of crude glycerol, an inexpensive renewable feedstock, for the economical production of polyhydroxyalkanoates (PHA) polymers. Crude glycerol is a byproduct of many industrial bioprocesses, and surplus amounts of it are released into the environment as waste, thereby necessitating the search for appropriate methods of its

Selective hydrogenation of crude glycerol to propanol

2017
Many EU directives regulate the emission of greenhouse gases from fossil fuels. Some of the fossil components have been replaced by bio-components which emit less greenhouse gases. The blending of bio-components will be regulated in the renewable energy directive (RED) from 2020 onwards.

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

Telomerization of crude glycerol towards new surfactant molecules

2008
A new catalyst system for the telomerization of butadiene with glycerol applying Pd-based triphenylphosphine complexes with methoxy functionalized ring systems was studied. Under different reaction conditions, the resulting complexes showed remarkable activity.
