Single-pipe-structure fixed bed reactor for teaching experiment

Abstract

The invention discloses a single-pipe-structure fixed bed reactor for teaching experiment. The fixed bed reactor is characterized in that a reaction pipe is arranged in a barrel; a stainless steel mesh and filler are arranged under the reaction pipe; heating devices at two sides of the barrel are used for carrying out heating reaction. The reactor is used for teaching experiment equipment, the structure of the reactor is greatly simplified, the reactor is easy to assemble and disassemble, and the cost of a teaching reactor experiment is reduced, and in addition, an internal cavity of the reactor is small in volume, so that the standing time of a gas phase raw material and a product in the reactor is reduced, the side reaction is reduced, and meanwhile, the conversion rate of the raw material is improved.

Description

technical field [0001] The invention relates to a fixed-bed reactor, in particular to a teaching experiment fixed-bed reactor used for the high-temperature and high-pressure reaction process of methane-carbon dioxide reforming and coal / coke gasification. Background technique [0002] Reactors and reaction devices, especially fixed-bed reactors, are mostly involved in the cultivation process of chemical engineering undergraduates and graduate students. Fixed bed reactors play an important role in the laboratory research and development stage, industrial scale-up and industrial production stages of chemical technology. Most of the fixed-bed reactors in existing experiments are combined structures with external pressure and internal heat. Generally, they are bulky, the internal structure of the reactor is complicated, and the manufacturing and maintenance costs are relatively high. In addition, during the high-pressure reaction process, due to the high internal pressure of the...
