Abstract

The invention relates to the technical field of clean energy, in particular to a coal-biomass co-processing technology, and provides a method for producing light oil by liquefaction of coal and biomass. The processing of 'compressing + pulverizing + re-pulverizing' is conducted on materials of coal and biomass firstly, slurry is then prepared, and biomass coal water slurry which has high solid content and can be steadily transferred by using a pump is obtained successfully. By performing liquefaction reaction for two times, it is ensured that the coal and the biomass can be thoroughly liquefied into liquid phase to improve the yield of liquid oil, the yield of the light oil is further improved through subsequent separation and hydrogenation procedures, the yield of low distillation range oil such as naphtha and the like in the light oil is particularly improved, and the residue content in subsequent light oil is reduced.

Description

technical field [0001] The invention relates to the technical field of clean energy, in particular to a co-smelting process of coal and biomass. Background technique [0002] At present, my country uses coal as the main energy source, and the traditional coal utilization method is combustion, but the problem of air pollution caused by coal combustion has become increasingly serious; moreover, the quality of coal in my country has declined year by year, which has increased the proportion of raw coal washed year after year, and coal washing wastewater has brought severe water pollution. Severe environmental problems have made the adjustment of energy structure one of the important tasks of my country's energy development. However, China's own energy resource storage is poor in oil and rich in coal, and it already needs to rely on a large amount of oil imports every year to meet the needs of production and development. If the country's energy structure is adjusted by reducing t...
