Method and apparatus for mixing a lignocellulosic material with enzymes

摘要

A method to treat a lignocellulosic material including: performing a steam explosion reaction on the lignocellulosic material and discharging a slurry from the; adding an alkali material to the slurry in a first conveyor; transferring the slurry with the alkali material from the first conveyor to a second conveyor; adding an enzyme solution to the slurry while in, entering or at the discharge of the second conveyor; transferring the slurry with the enzyme solution from the second conveyor slurry to a mixer; mixing the slurry in the mixer, wherein a second portion of the enzyme solution is added to the slurry during the mixing, and transferring the slurry with the enzyme solution from the mixer to a first reactor vessel wherein the slurry in the first reactor vessel undergoing enzymatic hydrolysis such that the viscosity of the slurry is reduced in the first reactor vessel.
