Abstract

The invention discloses a preparation technology of methanol-to-hydrocarbon combustion gas for urban pipelines, and relates to the technical filed of application methods of a methanol substituent fuel. The technology comprises the following steps: preheating methanol, carrying out heat exchange to gasify methanol, introducing the gasified methanol into a superheater, heating, and carrying out a catalysis reaction on the heated gasified methanol under the catalysis of a catalyst to generate C1-C5 component-containing hydrocarbon combustion gas. The hydrocarbon combustion gas can be introduced into the urban pipelines and can be used by people. The technology converting methanol into the hydrocarbon combustion gas has good economic benefit, and improves the calorific value of the raw material methanol to 28372KJ / KG from 20083KJ / KG, so the calorific value increases by 41.27%; and the caloric power of CH of methanol is completely released, energy consumption in the methanol conversion process is small, and reaction heat heats the raw material through the heat exchanger and is fully utilized, so the energy saving benefit is high.

Description

technical field [0001] The invention relates to an application method of methanol substitute fuel, in particular to a production process for producing hydrocarbon gas from methanol used in urban pipelines. Background technique [0002] Methanol (structure CH 3 OH), its molecular weight is 32.04. Under normal temperature and pressure, pure methanol is a colorless, volatile, flowable flammable liquid with a similar smell to ethanol. Methanol can be wirelessly miscible with water, ethanol, ether and many other organic liquids , but not mutually soluble with aliphatic hydrocarbons. [0003] The main production method of methanol is that industrial methanol synthesis is CO and H obtained from coal gasification or natural gas conversion. 2 Synthesis gas is synthesized through catalysts (mainly copper metal) under high temperature and high pressure. The main purpose is that methanol is an important chemical raw material. In the organic synthesis industry, it is an important basic...
