[0019] Take 1 molar concentration of copper nitrate, zinc nitrate, aluminum nitrate mixed solution, Cu: Zn: Al = 5: 3.5: 1.5 in the solution, co-precipitate with ammonium carbonate at 70 ° C, after washing, dry at 120 ° C , calcined at 400°C, and then added graphite flakes to make a cylindrical catalyst A with a diameter of φ4mm×5mm.

[0020] Get above-mentioned catalyzer and pack in the reaction tube of the reactor of the present invention, the stainless steel tube that reaction tube size is phi 25mm * 3mm * 1200mm. Before operation, treat it with hydrogen-nitrogen mixed gas with a hydrogen content of 0.5% for 1 hour, the pressure is 0.5MPa, and the vapor space velocity is 300h -1 . Then gradually raise the temperature to 250° C., and gradually increase the hydrogen content in the hydrogen-nitrogen mixture to 2% of the hydrogen content, until the hydrogen content at the outlet and inlet of the reactor is basically the same.

Abstract

A process and its reactor for preparing CO and H2 from methanol feature that the CuO / ZnO / Al2O3 series catalyst is used and the reaction takes place at 160-330 deg.C, under 0-3 MPa and with 0.1-3 / h for space velocity of methanol, preferably 0.5-2.0 / h.

Description

field of invention [0001] The present invention relates to a kind of method that utilizes methanol to produce carbon monoxide and hydrogen, specifically adopts CuO / ZnO / Al 2 o 3 It is a catalyst. Under certain process conditions, methanol is used to produce a mixed gas of carbon monoxide and hydrogen, and then the mixed gas is separated to obtain carbon monoxide and hydrogen respectively. [0002] The invention also relates to a reactor used in the process of producing carbon monoxide and hydrogen from methanol. Background technique [0003] Carbon monoxide is an important raw material in fine chemical and pharmaceutical industries. The mixture of carbon monoxide and hydrogen can be widely used in metallurgy and machinery manufacturing and other industries. [0004] Chinese patent (ZL96102205.1) discloses a method for hydrogen production by steam reforming of methanol, using CuO / ZnO / Al 2 o 3 It is a catalyst, its purpose is to produce hydrogen; the concentration of carbon...
