The decoupling reactor comprises a reaction pipe main body, a thermocouple side pipe and an instant feeding side pipe, wherein the reaction pipe main body sequentially comprises a lower pipe section, a lower annular space section, a lower porous plate, a reaction section, and an upper pipe section from bottom to top, the thermocouple side pipe and the instant feeding side pipe are arranged at two sides of the reaction section, one end of the thermocouple side pipe is connected with the outer side wall of the reaction section, and one end of the instant feeding side pipe is connected with the outer side wall of the reaction section. The decoupling reactor is used in the field of analysis and testing of a high-temperature chemical reaction.

Description

technical field [0001] The invention relates to a reactor, in particular to a decoupling reactor based on atmosphere switching, and belongs to the field of high-temperature chemical reaction analysis and testing. Background technique [0002] High-temperature gas-solidification chemical reactions widely exist in the actual industrial process of thermal conversion and utilization of various solid carbon-based fuels. The high-temperature thermochemical reactions of solid carbon-based fuels in practical industrial installations can usually be decoupled into two reaction stages: high-temperature fast pyrolysis and burnout or gasification of residual coke. According to the needs of the research, the high-temperature gas-curing chemical reaction of solid carbon-based fuels is often decoupled into multiple reaction stages in laboratory research, and the reaction atmosphere and reaction temperature of each reaction stage may be quite different. [0003] Various traditional micro an...
