Normal-pressure fixed bed type catalyst evaluation device

The utility model relates to a normal pressure fixed bed type catalyst evaluation device which comprises a three-way valve, one end of the three-way valve is connected with a nitrogen pipeline, one end of the three-way valve is connected with a methanol pipeline, and the other end of the three-way valve is connected with a fixed bed reactor. And one path is sequentially provided with a heat tracing band and a six-way valve. A preheating jacket is arranged on a methanol liquid inlet pipeline and aims to preheat and gasify methanol. An inlet of the fixed bed reactor is arranged at the top end and connected with a methanol liquid inlet and a nitrogen carrier gas port through a three-way valve. The fixed bed reactor is divided into a filler pipe and a temperature measuring sleeve. A heating sleeve is arranged outside the fixed bed and adopts an electric heating mode. A fixed bed outlet pipeline wraps a heat tracing line for heat preservation, and an outlet pipe is connected with a six-way valve for sampling near
