preparation example Construction

[0032] The preparation method of the nano-catalyst is as follows: under the protection of nitrogen, a certain amount of soluble salt containing metal ions and a stabilizer are mixed and dissolved in water, a metal reducing agent is added, and the nano-metal particles are produced after fully stirring. The metal particles are separated by magnetic separation, washed with water, and then dispersed into water containing stabilizers to form a liquid phase medium. The stabilizer is preferably polyvinylpyrrolidone.

[0033] In the Fischer-Tropsch synthesis method provided by the present invention, the liquid phase medium is water, alcohol, refluxing hydrocarbon or ionic liquid. Preferably, the liquid phase medium is water. Preferably, the liquid medium contains a polymer stabilizer to maintain high dispersion of the metal nanoparticles, and the stabilizer is preferably polyvinylpyrrolidone.

Embodiment 1

[0049] Use as attached figure 1 The shown Fischer-Tropsch synthesis reaction device, the structure of the microreactor is as attached Figure 2-4 shown. The diameter of the nozzle of the mixer is 0.4 mm. The microchannel reactor includes reaction microchannels and heat exchange microchannels. The dimensions of all microchannels are 1 mm high and 2 mm wide. 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. The ratio of the volume flow rate of the synthesis gas entering the mixer to the liquid phase (catalyst liquid) containing nano metal catalyst particles is 30:1. The nano particles contained in the catalytic liquid are cobalt catalysts, and polyvinylpyrrolidone is added to maintain the stability of the catalytic liquid. The concentration of cobalt in the catalytic liquid is 0.05mmol / mL. The ratio of synthesis gas tail gas to circulating synthesis gas is 1:...

Abstract

The invention relates to a Fischer-Tropsch synthesis reaction apparatus and a Fischer-Tropsch synthesis method. The reaction apparatus comprises a mixer, a micro-reactor and a separator which are connected in order, wherein the micro-reactor is composed of a material flow inlet, a reaction micro channel, a heat exchange micro channel and a product outlet, the material flow 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, wherein, the cross-sectional area of the reaction micro channel is 0.01-100 mm<2>, and the distance between the adjacent reaction micro channels is 0.5-20 mm. The Fischer-Tropsch synthesis reaction apparatus employs the micro-reactor, and has the advantages of small reaction equipment volume and compact structure, and has the characteristics of good mobility and low investment.

Description

technical field [0001] The invention relates to a Fischer-Tropsch synthesis reaction device and method, more specifically, to a device and method for Fischer-Tropsch synthesis through 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 small and the sources of synthesis gas are ...
