Cross-flow process for the production of decomposable soluble products from a slurry of solids

摘要

A process is described for the production of decomposable soluble products from a slurry of solids in which the slurry is convey axially through the reactor and excess liquid is removed radially through the walls of the reactor. The primary example is the hydrolysis of lignocellulosic biomass to form sugars, usually using an acid catalyst. In one variation of the process liquid and possibly steam are added through the inner wall of the reactor to provide additional flow in the radial direction and to control the temperature. Pressures are maintained such that the product stream is thermally quenched due to partial flashing as it leaves the reactor.
