Abstract

The invention discloses a continuous biomass depolymerization method. The method comprises steps as follows: a material is conveyed to a double-valve feeder through a feeding port and conveyed to a horizontal reactor through the double-valve feeder; the material is subjected to first depolymerization by use of the horizontal reactor and is continuously conveyed to a vertical reactor for second depolymerization to obtain separated liquid depolymerized product and solid residues, continuous feeding of biomass is realized through the double-valve feeder, the automation degree of a hydrolysis process is improved, real continuous operation is realized, and the depolymerization effect of the material is improved through the horizontal reactor and the vertical reactor.

Description

technical field [0001] The invention relates to the technical field of chemical industry technology equipment and energy of biomass, in particular to a continuous depolymerization method of biomass. Background technique [0002] The large-scale use of petroleum fossil fuels has caused serious environmental pollution problems, so the development of renewable energy has attracted more and more attention. Biomass is currently considered to be the only renewable resource that can be converted into liquid fuels and bio-based new materials, and crop straw-like lignocellulose is the most important biomass resource. [0003] In recent years, the research and development of high-efficiency conversion and utilization technology and equipment of biomass straw has become a hot research direction at home and abroad. The aqueous phase depolymerization of straw has the advantages of high efficiency, strong adaptability, high added value of products, and easy connection with existing chemi...
