In recent years, fine chemicals, hydrogen peroxide anthraquinone process, powder metallurgy, oil hydrogenation

3、, hydrogenation of forestry products and agricultural products, bio-engineering, petroleum refining hydrogenation and hydrogen fuel the rapid development of clean vehicles, etc., the demand for pure hydrogen rapidly increasing. This paper analyzes the type structure of several micro-reactors and res

4、earches the strengths and weaknesses of all kinds of micro-reactors. Its basic principle, process flow and technological design about the equipment are described in this paper. So a new kind of wire or screen filled methanol steam reforming micro-reactor are designed. The next step is to calculate t

5、he stress and intensity of the main parts. Heating and the resistance of the reactor are designed and catalyst on the surface of the wire is coated. Finally taking the experiment, researching the experimental data and assessing the experimental results are my last several steps.
