Problems solved by technology

Traditional catalytic bed reactors, such as fixed bed reactors and fluidized bed reactors, have shown their limitations in many engineering applications due to their respective shortcomings in material transfer and heat transfer
For example, fixed bed reactors have problems such as uneven bed temperature distribution, hot spots / cold spots, and small heat transfer area per unit volume, which cannot meet the heat transfer requirements of some strong exothermic / endothermic reactions; fluidized bed reactions There are problems such as large material backmixing and serious catalyst wear

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a reaction device and reaction equipment. Background technique [0002] Most of the gas-solid catalytic reactions in the chemical industry are strongly exothermic or endothermic, such as methanol synthesis, carbon monoxide shift, synthesis gas to methane, ammonia synthesis, methanol to olefins, natural gas reforming to hydrogen, etc. The research and improvement of catalytic bed reactors in these strong exothermic or strong endothermic reactions has always been a research hotspot. Traditional catalytic bed reactors, such as fixed bed reactors and fluidized bed reactors, have shown their limitations in many engineering applications due to their respective shortcomings in mass transfer and heat transfer. For example, fixed bed reactors have problems such as uneven bed temperature distribution, hot spots / cold spots, and small heat transfer area per unit volume, which cannot meet th...
