Description
Technical field
The utility model is related to synthesis gas preparing technical field, is set more particularly, to a kind of synthesis gas preparation facilities and recovery
It is standby.
Background technology
At present, the coal chemical enterprise in association area and other pyrolysis of coal enterprises are by the oven gas produced in enterprise production process
Or pyrolysis gas is used to produce synthesis gas, the synthesis gas includes H2、CO、CO2Etc., and further prepare first using the synthesis gas
The chemical products such as alcohol, ethylene glycol, synthesis ammonia.Specifically, the existing technology for preparing above-mentioned synthesis gas mainly has two kinds, respectively pure
Oxygen catalyzing part oxidation technology and pure oxygen non-catalytic partial oxidation technology, two kinds of technologies be all using oxygen combustion oven gas or
Hydrogen partial or/and methane in pyrolysis gas make the hydrocarbon in oven gas or pyrolysis gas for the heat needed for conversion process is supplied to
Class under the high temperature conditions with steam generation conversion reaction, and then by the hydrocarbon conversion be synthesis gas H2、 CO、CO2.Wherein, oven gas
The fundamental reaction equation of conversion is as follows：
Oxidation reaction:
CH4+2O2=CO2+H2O-802.6KJ/mol
CH4+0.5O2=CO+2H2-27.32KJ/mol
H2+0.5O2=H2O-285.8KJ/mol
Reduction reaction:

Agent is failed.The tediously long and corresponding cleaning equipment of the desulfurizing and purifying flow is complicated, and then makes execution cycle and the difficulty of the technology
Increase, that is, cost is high.Meanwhile, in the synthesis gas produced by the technology, the component of hydrogen is too high, and the component of carbon is on the low side,
The hydrogen-carbon ratio that this kind of component can not meet subsequent processing synthesis gas requires that having a large amount of hydrogen in subsequent handling speeds to put.
For above-mentioned pure oxygen non-catalytic partial oxidation technology, although participation of the technology without catalyst, Yi Jiwu
Desulfurizing and purifying process is needed, however, the reaction temperature of the technology need to reach more than 1300 DEG C, the heat needed for preparation process needs combustion
More oven gas or pyrolysis gas are burnt, so that the energy consumption of whole preparation facilities and investment increase, that is, cost is high.Meanwhile, lead to
In the synthesis gas for crossing technology production, the component of hydrogen is too high, and the component of carbon is on the low side, and this kind of component can not meet subsequent processing conjunction
A large amount of hydrogen are had into the hydrogen-carbon ratio requirement of gas, in subsequent handling to speed to put.
To sum up, there is prepared synthesis in existing pure oxygen catalytic partial oxidation technology and pure oxygen non-catalytic partial oxidation technology
The defect that the hydrogen-carbon ratio of gas is unreasonable and cost is high.
