Abstract

The invention provides a coal powder hydropyrolysis and gasification integrated system and a treatment method thereof. The system comprises a feeding unit, a reaction unit and a separation unit, wherein the reaction unit comprises a lifting pipe reactor and a gasification furnace; the separation unit comprises a gas-solid separation device and an oil-gas separation device. According to the coal powder hydropyrolysis and gasification integrated system, coal powder hydropyrolysis and gasification are coupled, so that graded transformation and comprehensive utilization of raw coal are realized, and the yield of a pyrolyzed oil product and the quality of the oil product are improved; meanwhile, internal circulation of materials in the system is realized and no byproducts are generated; the utilization rate of the materials and energy is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of coal chemical industry, and relates to a pulverized coal hydropyrolysis and gasification integrated system and a processing method thereof. Background technique [0002] With the increasingly serious problems of energy shortage and environmental pollution, it has become a consensus to develop clean and efficient technologies for utilizing chemical raw materials. In the structure of chemical raw materials, coal accounts for more than half. Therefore, the development and promotion of clean coal technology, the realization of graded transformation of coal resources, and rational and effective utilization have become research hotspots. [0003] In the existing technology, the tar yield of coal pyrolysis technology is low, and the content of heavy components is high, which is not conducive to the subsequent processing of tar. At the same time, the price of powdered coke is low, and subsequent utilization is al...
