A multi-channel differential reaction device

Abstract

The invention discloses a multi-channel differential reaction device, and belongs to catalyst analysis and evaluation reaction device. The multi-channel differential reaction device comprises four systems of a gas-liquid charging system of (1)-(3), a multi-channel reactor system of (4)-(6), an automatic control system (7) and an on-line analysis system (8). The multi-channel differential reaction device adopts a high pressure distributor (4) to distribute a raw material into reaction tubes (6) of all channels. Temperatures of the all reaction tubes (6) are controlled unitedly by a heating furnace (5). The multi-channel differential reaction device is provided with the automatic control system (7) and the on-line analysis system (8) and can satisfy that in a reaction process, at any time, reaction products in all channel reaction tubes can be taken out on line simultaneously, are placed respectively in corresponding quantitative rings and are analyzed orderly through use of a gas chromatography. The catalyst analysis and evaluation reaction device can evaluate a catalyst rapidly and also evaluate and screen multiple catalysts simultaneously under a condition thus saves time spent on research and exploitation of a novel catalyst.
