Title:
SYSTEM AND METHOD FOR CONTINUOUSLY PREPARING FURFURAL USING LIGNOCELLULOSIC RAW MATERIAL
Document Type and Number:
WIPO Patent Application WO/2019/109835
Kind Code:
A1
Abstract:
The present invention discloses a system and a method for continuously preparing furfural using a lignocellulosic raw material. The system comprising an acid liquid outputting unit, a raw material mixing unit, a feeding unit, a main reaction unit, a discharging unit, a steam stripping reaction column, a separation unit, and a purification unit. The method comprises an acid liquid outputting step, a raw material mixing step, a feeding step, a hydrolysis reaction step, a discharging step, a steam stripping reaction step, a separation step, and a purification step. The present invention is a genuine continuous production system, which realizes temporally continuous acquisition of products, reduces labor intensity, and improves production efficiency. The whole process has a reasonable design, high furfural yields and low unit energy consumption.
