Embodiment 1

[0035] The microreactor uses figure 1 The structure shown, such as figure 1 As shown, the synthesis gas enters the reaction microchannel 4 of the microreactor from the gas phase inlet 1. The width of the reaction microchannel 4 is 2mm, the height is 1mm, and the length of the region including all the reaction microchannels is 1000mm. The flow diverting member 6 is rhombus-shaped, the inner angle of the obtuse angle of the rhombus is 120 degrees, and the inner angle of the acute angle is 60 degrees. In the reaction microchannel 4, the catalyst coated on the surface of the channel is a Co-based catalyst. For the coating method of the catalyst carrier, see patent CN103212450A. After the catalyst layer is conventionally impregnated, dried, calcined and reduced, the loading of the metal active component Co is completed. The thickness of the catalyst layer is about 100 μm, and the content of Co is about 35%.

Abstract

The invention provides a Fischer-Tropsch synthesis microreactor and a Fischer-Tropsch synthesis method. The microreactor comprises a gas phase inlet, a reaction micro-channel, a heat exchange micro-channel and a product outlet, wherein the gas phase inlet is communicated with one end of the reaction micro-channel; the other end of the reaction micro-channel is communicated with the product outlet; the heat exchange micro-channel is not communicated with the reaction micro-channel; the reaction micro-channel adopts a net-shaped cross structure; the heat exchange micro-channel also adopts the net-shaped cross structure; the reaction micro-channel is coated with a catalyst layer; a catalyst is selected from one or a mixture of metallic elements including iron, cobalt, nickel and ruthenium. The Fischer-Tropsch synthesis microreactor is small in size and compact in structure and has the characteristics of good movability and low investment.

Description

technical field [0001] The invention relates to a Fischer-Tropsch synthesis microreactor and a Fischer-Tropsch synthesis method, more specifically, to a system and method for implementing a Fischer-Tropsch synthesis by using a microchannel reactor. Background technique [0002] Fischer-Tropsch synthesis technology is a very important alternative energy technology, which can convert synthesis gas (H 2 and CO) are converted into hydrocarbons by catalysts. Generally, the Fischer-Tropsch synthesis reactor includes three forms: fixed bed, fluidized bed and slurry bed. The catalyst in the reactor is solid particles, and the synthesis gas enters the reactor and reacts with the solid particles. The above three Fischer-Tropsch synthesis reactors are suitable for the situation of large processing capacity and high output, and the scale of the reactor is relatively large, and the equipment basically does not have mobility. However, for the case where the amount of synthesis gas is sm...
