Abstract

The invention provides a methanol cracking device, which consists of a methanol tank, a filter, a methanol pump, a flow control valve, a three-way valve, a solenoid valve, a reaction section, a one-way valve, a cracked gas storage tank, a pressure sensor, and a digital pressure display , needle valve and other components. The reaction section is composed of an evaporation tube, a throttle tube and a cracking tube. The three-section pipeline is in a spiral shape and connected by a ferrule joint. The cracking tube is filled with a low-temperature catalyst that promotes the reaction. The invention can improve the vaporization effect of methanol and improve the reaction efficiency of cracking reaction by arranging evaporation tubes and throttling tubes with different diameters. The whole set of device is convenient to install and disassemble, has good interchangeability, simple structure and low manufacturing cost.

Description

technical field [0001] The invention belongs to the technical field of gas cracking devices, in particular to a methanol cracking device. Background technique [0002] Methanol exists in liquid form at normal temperature and pressure, its density is similar to that of gasoline, easy to store, easy to transport, its octane number is also high, the molecule contains 50% oxygen, the burning speed is fast, and the range of lean burn is wide. An oxygen-enriched, environmentally friendly, high-energy fuel. In order to ensure national energy security, according to the energy characteristics of my country's poor oil and rich coal, carry out basic research on the application of coal-to-methanol (methanol can be synthesized by gasification of carbon-containing organic matter, so it is also a renewable energy) oxygenated fuel vehicles, and establish alcohol The theoretical system of fuel combustion, emission and its control is particularly important. After years of research and develo...
