More Information
Summary:The present invention discloses a system and a method for continuously preparing furfural using lignocellulosic raw material. The system comprises an acid solution output unit, a raw material mixing unit, a feeding unit, a main reaction unit, a discharging unit, a stripping reaction column, a separation unit, and a purification unit. The method comprises an acid solution output step, a raw material mixing step, a feeding step, a hydrolysis reaction step, a discharging step, a stripping reaction step, a separation step, and a purification step. The present invention is a genuine continuous production system, which achieves continuous acquisition of products in terms of time, reduces labor intensity, and improves production efficiency. The whole process has a reasonable design, high furfural yields and low unit energy consumption.
