Catalytic Conversion Of Glycerol Fine Utilization

Catalytic conversion of glycerol fine Utilization

Biomass energy mainly refers to bio-ethanol, bio-diesel and bio-hydrogen production. Wherein, biodiesel is an alternative to animal fats in the glyceryl group with methanol or ethanol and other lower alcohols obtained long-chain fatty acid alkyl monoester. The main characteristics of biodiesel is low sulfur content, high oxygen content, free of environmental pollution caused by aromatic hydrocarbons; has good low temperature performance; has better lubricating properties; has a good safety performance; with more good combustion properties (high cetane number); diesel engine without modification, can be added directly.

The main byproduct of biodiesel production is glycerin, each producing about 9 kg of biodiesel to obtain 1 kg of crude glycerol byproduct. Purification of the latter subject to filtration, purification, chemical additives and distillation process, if used in food, cosmetics, pharmaceuticals and other areas, it needs to be further bleaching, deodorization, ion exchange to eliminate trace impurities. The cost of crude glycerin made by the pure glycerol is very expensive, how to use new technology and new technology research and development and processing costs low, there is a huge potential for development of crude glycerin, key and guarantee for sustainable development of biodiesel industry.
