Recovery and utilization of crude glycerol, a biodiesel byproduct

Abstract

In this review, we summarize the latest technologies for the recovery and purification of crude glycerol and applications of crude glycerol, with focus on its chemical conversion.

Crosslinked polymers based on monomers derived from renewable resources and their application potential

“…Plant oil and fat represent the main resources for triglycerides that are hydrolyzed into fatty acids and glycerol by chemical or enzymatic processes [4,20]. Though industrial use of plant oil and fat, for example, for biodiesel production from triglycerides as an alternative to petrochemical diesel or for monomer synthesis, competes with food production, only cooking oil available as waste from industry, restaurants, or household should be utilized for fatty acid manufacturing.…”

Glycerol Electro-Oxidation in Alkaline Medium with Pt-Fe/C Electrocatalysts Synthesized by the Polyol Method: Increased Selectivity and Activity Provided by Less Expensive Catalysts

“…Glycerol, a renewable, low-cost, and widely available compound, is a waste product from the transesterification of vegetable oils for biodiesel production—10% m/m of the products is glycerol [ 1 , 2 , 3 , 4 ]. Given that the rate of world biodiesel production is high, new applications for glycerol as a platform molecule for the chemical industry must be found [ 2 , 3 , 4 , 5 ].…”

Given that the rate of world biodiesel production is high, new applications for glycerol as a platform molecule for the chemical industry must be found [ 2 , 3 , 4 , 5 ]. The industrial demand for value-added products, including C3 compounds such as glyceric acid, tartronic acid, glyceraldehyde, dihydroxyacetone, hydroxypyruvic acid, and mesoxalic acid derived from glycerol oxidation, is high because these compounds have numerous commercial applications.…”

Crosslinked Polymers Based on Monomers Derived from Renewable Resources and Their Application Potential

“…[12] SOURCES FOR THE STARTING MATERIAL Plant oil and fat represent main resources for triglycerides that are hydrolyzed into fatty acids and glycerol by chemical or enzymatic processes. [4,15] Though industrial use of plant oil and fat e. g. for biodiesel production from triglycerides as alternative to petrochemical diesel or for monomer synthesis compete with food production, only cooking oil available as waste from industry, restaurants or household should be utilized for fatty acid manufacturing. Furthermore, the glycerol formed as by-product in the biodiesel production may be useful for esterification of oleic acid instead of using ethylene glycol as shown in Scheme 1.…”
