Abstract

The invention provides an isothermal conversion device, and a syngas complete-conversion reaction system comprising the same. The isothermal conversion device comprises a shell, a gas collector and atleast one first heat exchange unit, the gas collector is arranged in the shell, the gas collector is provided with a gas-to-be-converted inlet and a converted gas outlet, and is used for performing acomplete-conversion reaction on syngas, and the gas-to-be-converted inlet extends to the external of the shell through a gas-to-be-converted conveying pipeline; and the first heat exchange unit is arranged in the gas collector, and a catalyst is arranged in a space among the gas-to-be-converted conveying pipeline, the first heat exchange unit and the gas collector. The isothermal conversion device can shorten the process route, reduce the resistance of the system and reduce the occupied area of the system when applied to the complete-conversion reaction process of the syngas.

Description

technical field [0001] The invention relates to the field of coal chemical industry, in particular to an isothermal shift device and a synthetic gas complete shift reaction system comprising it. Background technique [0002] Adjustment of CO and H in crude synthesis gas produced by coal gasification by carbon monoxide shift reaction 2 Ratio, so as to produce qualified shift gas, which is used to synthesize chemical products such as methanol, ethylene glycol, natural gas, polyols, and coal-to-oil. [0003] Transformation includes complete transformation and partial transformation process. For example, coal-to-hydrogen adopts complete transformation process, and the volume fraction of the hydrogen product sent out of the coal-to-hydrogen unit is not less than 99.5%. Coal-to-methanol adopts a partial shift process to adjust the hydrogen-carbon ratio in the synthesis gas, and the H in the shift gas discharged from the carbon monoxide shift unit 2 The / CO ratio is about 2.05 to...
