Deep eutectic solvents for catalytic biodiesel production from liquid biomass and upgrading of solid biomass into 5-hydroxymethylfurfural

Abstract

Serious environmental issues triggered by abundant carbon dioxide emissions and gradual depletion of traditional fossil fuels are calling for the development of renewable energy. Efficient catalytic valorization of renewable liquid/solid...

Current advances and future outlook of heterogeneous catalytic transesterification towards biodiesel production from waste cooking oil

“…352 During heterogeneous catalysis, a few of the reactants spread throughout the catalyst surface and are adsorbed onto the active phases by the creation of chemical affinity. 120 After the reaction, the products spread and desorb from the catalyst's surface, leaving the active site free for a new molecule to adsorb on it and thus regenerating the catalyst. 121 Heterogeneous catalysts have attracted a lot of scientific and industrial recognition in recent years for producing biodiesel from WCO because of their affordability, non-corrosive and recyclable nature as shown in Fig.…”

Deep eutectic solvents as an emerging green platform for the synthesis of functional materials

“…It was calculated that the addition of a DES reduced the hydrogen bond strength between microalgal organisms, which further lowered the energy barrier for depolymerization and led to better lipid extraction. In addition to this, He et al 66 in their latest work cited the development of DESs for application to biodiesel and HMF, which is another way to add value to biomass by converting the abundant renewable liquid/solid biomass resources through the excellent properties of DESs, such as low volatility, wide tunable intervals, and low cost.…”

Selective Oxidation of Glycerol to Lactic Acid Catalyzed by CuO/Activated Carbon and Reaction Kinetics

“…In the field of renewable energy utilization, biodiesel has broad development prospects and has received widespread attention. − During the production process of biodiesel, a large amount of byproduct glycerol is inevitably generated, with 10 kg of glycerol produced for every 100 kg of biodiesel. − The continuous large-scale production of biodiesel has directly led to a decrease in glycerol market prices. However, glycerol can be used as an inexpensive raw material to produce high-value-added chemicals, such as lactic acid (LA), dihydroxyacetone (DHA), acrylic acid, 1,2-propanediol, etc. − …”
