Description

technical field [0001] The invention relates to a high-pressure reaction device, in particular to a high-pressure reaction device for hydrothermal liquefaction of biomass cellulose, belonging to the technical field of biomass conversion. Background technique [0002] As a renewable energy source, biomass can be divided into flora biomass and fauna biomass. Plants are one of the most important biomass. The main component is lignocellulose, which is mainly composed of cellulose, hemicellulose and lignin. Among them, cellulose is one of the main components of biomass cell walls such as plants, algae and fungi. , as the most abundant polymer on the earth, the average molecular weight of cellulose is about 100,000, and the annual output is about 1.5×1012t. Therefore, the research on the transformation and utilization of cellulose has very important theoretical and practical significance. [0003] Because the molecular structure unit of cellulose is glucose, it has a wide range o...
