The invention discloses a universal diverter and high-flux parallel catalytic reacting device in the fluid-solid multiphase catalytic reaction, which comprises the following parts: diverter (can be used individually), flow controller, parallel reactor, temperature controller, cooler and product collector, wherein the reacting fluid enters the flow controller to control the total flow of one fluid, which is diverted by diverter to mix the multipath fluid with the same path number as each single diverter number; each path loads one catalyst to catalyze the reacting fluid, which displays the property of catalyst. The diverter is easy to control shunt current in the combined chemical domain, which can be used in other domains with multipath diverting individually. |
