Abstract

The disclosed mobile biomass liquefaction system comprising: a biomass gasification furnace, a fuel decontamination plant, a fuel generating set, a biomass pyrolysis furnace with heat from the firing of gasified fuel and incondensable gas, a cooling tower, and a pretreatment device. This system realizes complete self-support for energy, can convert the biomass into bio-oil locally for further centralized treatment, and has high operation efficiency for wide application range.

Description

technical field [0001] The invention relates to a biomass liquefaction system. Background technique [0002] Biomass is a renewable resource that can be converted into liquid fuel. Its liquid products have the advantages of environmental friendliness, high energy density, easy storage, and easy transportation. They can be used as fuel for boilers, gas turbines, and engines, and can be extracted from them. valuable chemical products. [0003] A variety of different biomass pyrolysis liquefaction devices have been developed, such as the fluidized bed reactor developed by the University of Waterloo in Canada, the rotating cone reactor developed by the University of Twente in the Netherlands, and the vacuum reactor developed by Laval University in Canada. However, the lateral mixing characteristics of biomass and bed material in the fluidized bed reactor are not good, and the high ratio of carrier gas to material leads to serious wear of materials and equipment, low energy util...
