Embodiment 1

[0079] A preparation method of a cobalt-based catalyst supported by mesoporous carbon material GMC, comprising the following steps:

[0080] (1) Preparation of ordered mesoporous carbon materials (GMC):

[0081] The mixture of SBA-15 and soybean oil (mass ratio 1:2) was mixed with a ball mill at 400rpm·min using the solid-liquid ball milling template method. -1 After ball milling for 5 hours at a rotating speed, mix evenly, then divide the mixture into three parts, and transfer them to a quartz tube furnace successively. 2 Under protection at 4°C·min -1 The temperature was raised to 700, 800 and 900°C for carbonization for 5 hours respectively, and three materials calcined at different temperatures were produced. Use NaOH solution (concentration 2mol / L) to etch three times, each etching time is 24h, so as to remove the hard template agent SBA-15, and finally obtain porous materials calcined at different temperatures, respectively marked as GMC-700, GMC -800, GMC-900.

Abstract

The invention discloses a mesoporous carbon material loaded cobalt-based catalyst and a preparation method thereof, and belongs to the technical field of metal catalysts. The preparation method of thecobalt-based catalyst comprises the steps: (1) dissolving Co(NO3)2.6H2O in an absolute ethyl alcohol solution; (2) immersing a mesoporous carbon material GMC into the solution obtained in the step (1), and evaporating in a rotary evaporator to obtain a mixture; and (3) putting the mixture obtained in the step (2) into a drying oven, and drying; and calcining to obtain the catalyst. The catalyst provided by the invention is higher in graphitization degree, more uniform in CoO particle dispersion, higher in CO conversion rate, lower in CO2 generation rate and better in C5+ selectivity.

Description

technical field [0001] The invention relates to a cobalt-based catalyst supported by a mesoporous carbon material and a preparation method thereof, belonging to the technical field of metal catalysts. Background technique [0002] Since the industrial revolution, human demand for energy has been increasing, and the limitedness of non-renewable resources such as oil and coal has forced people to seek new energy sources, such as nuclear energy, wind energy, and solar energy, which are all hot topics for research and discussion. Among them, biomass is one of the core topics. It has the advantages of wide sources, various types, and great development potential. People use biomass to convert it into fuel and electricity, which not only solves the energy problem, but also recycles some waste biomass resources. [0003] Porous carbon materials not only have the advantages of acid and alkali high temperature resistance, stable chemical properties and low cost of carbon materials, b...
