Apparatus and method of continuous gasifying preparing carbonic oxide from pure oxygen coke

Abstract

the invention discloses a carbonic oxide preparing device and method through continuous gasification of pure oxygen coke, which is composed of fixed bed gas producer with gas outlet pipe on the furnace roof, wherein the water jacket is set on the inner wall of gas producer, whose height is 2.6-5.2 m at 0.2-1.6Mpa bearing pressure; the coke distributor connects coke inlet, which is set in the inlet; the level distance between the bottom of coke distributor and packing head on the water jacket is 200-600mm; the height of entocineria layer in the gas producer is at least 1200mm; the idle course height between coke layer roof and coke inlet is 2+-0.5m.

Description

technical field [0001] The invention relates to a device and a method for preparing carbon monoxide from pure oxygen coke, in particular to a device and a method for preparing carbon monoxide from pure oxygen coke in a fixed bed gas generator. Background technique [0002] Carbon monoxide (CO) is one of the important chemical raw materials for oxo synthesis. The traditional preparation method of CO is to separate high-purity CO from gas rich in carbon monoxide through pressure swing adsorption, COSORB, deep freeze separation and other processes. Since the 1990s, the process and equipment for preparing carbon monoxide from pure oxygen, coke, and carbon dioxide have been developed, and have played an active role in the field of carbon monoxide chemical industry. [0003] The process and equipment for preparing carbon monoxide from pure oxygen, coke, and carbon dioxide must have abundant and available CO 2 resources; for those who do not have CO 2...

AI Technical Summary

Problems solved by technology

Due to the limitations of the existing process, the carbon monoxide content in the crude gas is 67% to 75%, and the carbon monoxide content in the crude gas is low (CO~67%, CO 2 ~33%), CO in carbon monoxide refining system 2 The load of cycle separation is too large, and the commercially available CO 2 When used as a raw material, it must also be refined accordingly (mainly desulfurization), so that the equipment of the production device is relatively large, the efficiency is low, the operation is complicated, and the production energy consumption per unit of product is relatively high.
