High temperature coke oven crude gas hydrogen generating system device and technique

Abstract

The present invention provides a system device of hydrogen preparing by dried gasification of the easy condensation component, high temperature desulphurization purification and part oxidation and reforming of low carbon hydrocarbon using high temperature coke-oven raw gas as raw material and its process, belonging to coke-oven raw gas hydrogen production process field. The hydrogen preparing system device of high temperature coke-oven raw gas is mainly adopts drying gasification furnace, high temperature desulphurization device, mixed conducting oxygen-permeable membrane reactor and mixed conducting oxygen-permeable membrane oxygen separator. The system device of the invention includes a high temperature coke-oven raw gas supplying system, an oxygen supply air supplying system, a high temperature vapor supplying system, a drying gasification furnace oxygen supplying system, a high temperature desulphurization system and a coal gas reforming reaction product output system. The advantages of the hydrogen gas system is that the high physical sensible heat and the high chemical energetic component of a mass high temperature coke-oven raw gas generated in the course of coal carbonization is fully converted to a oxygen as possible; since oxygen supplying by adopting dried gasification, high temperature desulphurization and mixed conductor oxygen-permeable membrane, the system has a high efficiency of hydrogen preparing, and an improved amplitude.

Description

technical field [0001] The invention relates to a system device and process for producing hydrogen by using high-temperature coke oven crude gas as raw material through dry gasification of easily condensable components, high-temperature desulfurization and purification, and partial oxidation reforming of low-carbon hydrocarbons, which belongs to coke oven gas hydrogen production process technology field. Background technique [0002] Chlorine energy has received more and more attention for its clean and efficient characteristics. With the rapid development of hydrogen energy utilization, where to get industrial-scale and economically competitive hydrogen has become an urgent and urgent problem to be solved. At present, there are many ways to prepare hydrogen. Although the use of renewable energy such as solar energy, wind energy, and geothermal energy to produce hydrogen is the most ideal mode, the hydrogen energy produced by using these renewable energy sources through pho...

Problems solved by technology

There are many coking plants without gas purification process, which directly vent and burn a large amount of coke oven crude gas generated during the coking process, resulting in a huge waste of energy and serious environmental pollution.
