Abstract

The invention relates to a chip type structure catalysis multiphase microreactor which comprises a microreaction chip and a structure catalyst and comprises a gas-liquid two-phase reactant distributor, a multiphase catalysis reaction chamber, heat exchange channels on two sides of the catalysis reaction chamber and heat exchange channels on two sides of the gas-liquid two-phase reactant distributor; and gas-liquid or liquid-liquid is uniformly distributed to an inlet of a catalyst with a high-precision structure at the rear end by utilizing a dendritic distribution form and T-shaped shear mixing, and flowing heat exchange areas are respectively arranged on the upper side and the lower side of the catalytic reaction chamber. By optimizing the structural design of the reactor, the reactor has the advantages of excellent mass transfer and heat transfer characteristics, controllable reactant retention time, narrow retention time distribution, personalized design of a catalyst structure according to a reaction system, easiness in amplification and the like, and solves the bottleneck problem that a homogeneous catalyst or a fine powder catalyst is difficult to separate from a product; and the chip type structure catalysis multiphase microreactor is widely applicable to petrochemical, chemical, pharmaceutical, environmental protection, food and other fields.

Description

technical field [0001] The invention relates to the technical field of microreactors, in particular to a catalytic multiphase microreactor with a chip structure. Background technique [0002] Among various forms of microreactors, the chip microreactor is unique in the field of actual production and application of microreactors due to its large heat transfer area, wide application range, and easy scale-up. However, for heterogeneous reaction systems containing solid-phase catalysts, existing chip-type microreactors have many inherent defects. For example: this type of chip microreactor catalyst mainly uses the catalytic form of homogeneous catalysis or suspended bed fluidized bed, that is, the catalyst particles are small, and they react while flowing in this chip microreactor, so there are many in practical application production. There is a process link—the separation of catalyst and product. The microchannel reactor requires the size of the microchannel to be as small as ...
