The application of process simulations in lignocellulosic biorefinery: a review

In recent years there has been a growing interest in the scale‐up and commercialization of lignocellulosic biorefinery. Process simulation is a crucial preliminary study, conducted at the system level, to evaluate the feasibility of industrializing biorefinery operations. Numerous research studies have been conducted on the application of process simulation in lignocellulosic biorefinery, making it essential to provide a detailed introduction to this topic. This paper summarizes two aspects of the application of process simulation in lignocellulosic biorefinery: the production of bioenergy and the production of biochemicals. The bioenergy section describes the application of process simulation to hydrochar, syngas, and bioethanol. The biochemicals section relates to the production processes for cellulose, lignin, and hemicellulose. Additionally, the research status of process simulation in biorefinery are detailed from the following aspects: physical property parameters, kinetic study, the variety of raw materials and validation. Finally, this paper discusses some advances in biorefinery process simulation. It is hoped that this paper will assist the industrialization of lignocellulosic biorefinery.
