Problems solved by technology

It can be seen from the above-mentioned patents and documents that traditional supported catalysts are usually prepared by an equal-volume impregnation method. Most of the active components of the catalyst obtained by this method are located on the surface of the carrier, and the particles cannot enter the pores. Phenomena such as sintered clusters appear

Embodiment 1

[0034] 3.0g mesoporous carbon (specific surface area is 1985m 2 / g, pore diameter is 3.8nm) is placed in a 500ml two-necked stainless steel flask, one port is directly connected to the water pump, and the other port is connected to a dropping funnel containing 280ml of cobalt nitrate ethanol solution. The concentration of the precursor liquid is 0.05mol / L. The system was vacuumized for 0.5h, and the vacuum degree of the system was 10 -5 Torr, then turn on the switch of the dropping funnel, mix the impregnating solution with the carrier and carry out continuous vacuum treatment, until dry under magnetic stirring. The obtained composite was calcined in an argon atmosphere in a tube furnace at a heating rate of 0.2°C / min, and the required catalyst was obtained after calcining at 300°C for 4 h, in which the loading of metal cobalt was 20wt.%.

[0035] The catalytic reaction is carried out in a fixed-bed reactor. Measure 2ml of the above-mentioned catalyst and put it into a reacti...

Abstract

A catalyst for preparing distillate oil co-production high alcohol with synthesis gas consists of active metal and a porous carbon material carrier, wherein the weight percentage of the active ingredient is 5-20%, and the weight percentage of the porous carbon material carrier is 80-95%. The catalyst is high in activity, selectivity of a product is easy to modulate, the product is higher in stability, and a preparation method has the advantages of simplicity and good practicability.

Description

technical field [0001] The invention belongs to a catalyst, a preparation method and an application, and in particular relates to a catalyst, a preparation method and an application for producing distillate oil from syngas for co-production of high-carbon alcohol. Background technique [0002] Fischer-Tropsch synthesis reaction refers to the conversion of carbon monoxide and hydrogen into hydrocarbons under the catalysis of iron, cobalt, ruthenium and other metals according to a certain ratio. It is the indirect conversion of coal and natural gas into clean chemicals (gasoline, diesel, alcohols, etc.) core process. Due to the increasing depletion of petroleum resources, while coal, natural gas, biomass and other resources are relatively abundant, starting from coal, natural gas, biomass and other carbon-containing resources to produce synthesis gas, and then preparing liquid fuel from the synthesis gas through the Fischer-Tropsch reaction, can be achieved within a certain pe...
