Introduction

This technology adopts glycerol as raw material and uses microbial fermentation to produce 1,3-propanediol, which has the advantages of high process selectivity, mild operating conditions and renewable rawmaterials, and has completed an industrial demonstration of 10,000 tons in China. The technology of this projectis to produce 1,3-propanediol by biofermentation using glycerol, a by-product of biodiesel, as raw material,realizing the "waste to treasure" of the by-product, which is milder and more environmentally friendly than thechemicalmethod.
