Zeolite-assisted etherification of glycerol with butanol for biodiesel oxygenated additives production

Sustainable Upgrade of Bioderived Glycerol to Solketal through Acetalization over Metal-Free Mordenite Catalysts

“…A huge amount of glycerol generated during biodiesel production makes glycerol cheaper and abundantly available. Glycerol can be utilized for the production of value-added chemicals like propanediol, ethers, solketal, etc. − However, utilization of crude glycerol on a commercial scale is challenging because crude glycerol contains 80–90% glycerol with 10–12% water and some other impurities like sulfated ash, MONG, and some acid, alkali, etc . The percentage of impurities varies with the source of biomass and the conversion process.…”

A highly efficient rod-like-CeO2-supported palladium catalyst for the oxidative carbonylation of glycerol to glycerol carbonate

“…As biodiesel is produced on a large scale, the use of GL has become an important factor affecting the development of the biodiesel industry. GL can be converted into valuable chemicals by reaction, such as acrolein, 3 glycerol ether, 4 1,2-propanediol, 5 lactic acid, 6,7 and glycerol carbonate (GLC). 8 GLC is an important derivative of GL with a high boiling point, high biodegradability, low flammability, and low toxicity.…”

Assessment on the Effect of Sulfuric Acid Concentration on Physicochemical Properties of Sulfated-Titania Catalyst and Glycerol Acetylation Performance

“…Abundant glycerol generated in India is reported to be approximately 1.9 million litres as a by-product from the biodiesel industry. Glycerol is a by-product from the transesterification process of vegetable oil with straight-chain alcohol and produces fatty acid methyl ester (biodiesel) as the main product [1]. The surplus of glycerol waste has led to the search for an alternative approach, such as valorisation or conversion into valuable chemical products [2].…”
