B3D reaction catalyst evaluation experimental device

Abstract

The invention discloses a B3D reaction catalyst evaluation experimental device which comprises a reaction kettle, an acetylene gas compressor, a mass flow meter, a formaldehyde solution storage tank, a formaldehyde solution delivery pump, a solution extraction pipeline, a filter back-flushing pipeline, a tail gas condenser, a solution cooler, a gas-liquid separator and a solution storage tank, wherein acetylene gas is compressed by the acetylene gas compressor, and enters the reaction kettle in a connection manner after being metered by the mass flow meter; a front buffer tank and a rear buffer tank are connected to the front and rear ends of the acetylene gas compressor; the formaldehyde solution storage tank is in pipeline connection with the reaction kettle through the formaldehyde solution delivery pump; one side of the reaction kettle is connected with a thermostatic water bath through a pipeline; the solution extraction pipeline, the filter back-flushing pipeline and the solution cooler are connected to the reaction kettle; the solution cooler is sequentially connected with the gas-liquid separator and the solution storage tank; the reaction kettle is sequentially connected with the tail gas condenser, a first flow meter and a flame arrester; the reaction kettle is connected with the tail gas condenser, a second flow meter and the front buffer tank to form a loop.

Description

Technical field [0001] The invention belongs to the field of experimental devices, and specifically relates to a B3D reaction catalyst evaluation experimental device. Background technique [0002] At present, all the copper catalysts required for the B3D reaction of the domestic BDO device are provided by foreign companies, and they are all their patented technologies. In order to protect their patented technologies from infringement, the supplier only provides the correct use of the catalyst and the relevant information for safe storage. Therefore, The domestic understanding of the catalyst is limited to application, and there is no in-depth understanding. Moreover, the catalyst supply is restricted by others. The catalyst price is relatively high, the product value-added space is small, the profitability of the enterprise is affected, and the catalyst ordering cycle is long, which has a certain impact on the safe and stable operation of the device. It is necessary to conduct r...

Problems solved by technology

At the same time, the process conditions and process parameters of B3D reaction are only limited to the information provided by foreign patentees. Due to the limitation of production equipment, it is impossible to conduct experiments on process condition optimization and process parameter adjustment.
