Abstract

Abstract:

In order to effectively apply the conventional catalyst-coating methods to microreactors , a new kind of corrugated sheet as catalyst support was proposed. Then , a machining method named multi-teeth rolling formation was developed to realize the rapid and continuous production of the sheet , and the influences of hobbing and pressing force on the sheet formation were finally studied. The results indicate that (1) there is a negative relationship between the teeth space and the pressing force; (2) when the sheet is fabricated by a group of identical rollers ,there forms regular corrugation and pubescence-like rough rolling surface , which facilitates the adhesion of the catalyst on the sheet; and (3) the catalyst can be tightly coated on the sheet surface by means of slurry-coating method.

Key words: multi-teeth rolling, formation, catalyst support, microreactor, corrugated sheet
