Problems solved by technology

However, at present, domestic and international methanol oxidation technologies have huge defects, which are highlighted in that the physical structure of the oxidation catalyst is single and rough, and the commonly used ones are hollow cylinders, which cause serious back-mixing, vortex, and turbulence of oxidation reaction materials, which have already Become a bottleneck in the development of methanol oxidation technology

Abstract

The invention discloses a bundle-type catalyst for oxidation of methanol. The bundle-type catalyst comprises a stainless steel corrugated screen, an active catalyst and a flat screen. The active catalyst is uniformly distributed on the flat screen. The stainless steel corrugated screen is tiled and stacked and coats the active catalyst, then the edge of the stainless steel corrugated screen is enclosed, the stainless steel corrugated screen and the active catalyst are rolled to form the bundle-type catalyst through one end as an axle core. The physical structure of the catalyst is changed so that the distribution form and flowing way of the reaction materials are greatly improved, product quality is improved, impurities are reduced, material consumption and energy consumption are further reduced and solid foundation is laid for methanol oxidation industrial large-scale development and production.

Description

technical field [0001] The invention relates to a packaged catalyst for methanol oxidation, which is used in the equipment and method for preparing formaldehyde by oxidation of methanol, and belongs to the technical fields of coal chemical industry and organic chemical industry. Background technique [0002] With the development of coal chemical technology, large-scale polymethyl dimethyl ether (DMMn) process equipment will be born. However, at present, domestic and international methanol oxidation technologies have huge defects, which are highlighted in the fact that the physical structure of the oxidation catalyst is single and rough, and the commonly used one is a hollow cylinder, which causes serious back-mixing, vortex, and turbulence of the oxidation reaction material. Become a bottleneck in the development of methanol oxidation technology. Therefore, it is imperative to break through these technical drawbacks. Contents of the invention [0003] The invention discl...
