Abstract

The invention discloses a natural gas hydrogen production and biomass liquefaction combined treatment system and process. The treatment system comprises a natural gas reforming hydrogen production unit, a synthesis gas proportion adjusting membrane separator, a synthesis gas compression unit, a biomass raw material pretreatment unit, a biomass liquefaction reactor, a carbon dioxide separation unit, a light hydrocarbon concentration membrane separator and a light hydrocarbon recovery unit. The invention further provides a treatment process adopting the treatment system. According to the combined treatment system, the biomass liquefaction reaction unit and the natural gas reforming hydrogen production unit are organically combined, the natural gas reforming hydrogen production unit can adjust the property of hydrogen required by liquefaction at any time according to different biomass raw materials, a water gas shift reaction unit and a hydrogen purification unit in the natural gas reforming hydrogen production unit are omitted, synthesis gas generated by the natural gas reforming hydrogen production unit is directly used in the biomass catalytic liquefaction process, the hydrogen cost is greatly reduced, and the hydrogen utilization rate is high.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, and in particular relates to a combined treatment system and treatment process of biomass catalytic liquefaction and natural gas reforming hydrogen production. Background technique [0002] Biomass is an important renewable resource. At present, the fuel produced from biomass has accounted for more than 5% of the total energy demand, of which about 41% comes from woody biomass raw materials. After the biomass is liquefied, high-value products such as diesel, aromatics, tar and light hydrocarbons can be obtained, and the utilization value is greatly improved. However, due to the high oxygen content in the biomass raw material, the properties of the liquefied oil are poor, and further hydrogenation treatment is required to obtain qualified products. [0003] Biomass catalytic liquefaction reaction is to introduce hydrogen in situ on the basis of liquefaction reaction, and carry out hydro...
