Abstract

The invention relates to a high-temperature and high-pressure semi-coke cooling and depressurizing method which comprises the following steps: I, filling a cooling gas into high-temperature and high-pressure semi-coke treatment equipment for a preset duration; II, after the cooling gas is stopped, inputting a high-temperature and high-pressure semi-coke material into the high-temperature and high-pressure semi-coke treatment equipment, and performing heat exchange on the semi-coke material with the cooling gas in the high-temperature and high-pressure semi-coke treatment equipment in the falling process; III, when the semi-coke material in the high-temperature and high-pressure semi-coke treatment equipment is accumulated to a preset height, stopping inputting the semi-coke material into the high-temperature and high-pressure semi-coke treatment equipment; and IV, releasing the pressure of the high-temperature and high-pressure semi-coke treatment equipment, so as to complete the operation of charging and releasing the pressure of the high-temperature and high-pressure semi-coke treatment equipment, and through the pressure release process, performing cooling and depressurizing treatment on the high-temperature and high-pressure semi-coke material for a second time. By adopting the cooling and depressurizing method, the high-temperature and high-pressure semi-coke material is subjected to effective and efficient cooling and depressurizing treatment, and the investment cost of treatment can be also greatly lowered.

Description

technical field

[0001] The invention relates to the technical field of high-temperature and high-pressure semi-coke cooling, and more specifically, relates to a method for reducing temperature and pressure of high-temperature and high-pressure semi-coke. Background technique

[0002] Coal cascade utilization is one of the effective ways to start from the chemical structure of coal, make full use of the aromatic and aliphatic functional group structures contained in coal itself, obtain high value-added oil products, improve process technical indicators, and realize efficient, reasonable and clean utilization of coal resources. one. Coal hydrogasification technology is one of the mainstream research and development directions for the existing coal cascade utilization. The hydrogasification reaction temperature is 700-950°C and the operating pressure is 4-10MPa. After the coal undergoes hydrogasification reaction, a large amount of high-temperature, high-pressure, low-sulfur, ...
