Problems solved by technology

Although there are reports of unsupported ruthenium-catalyzed CO hydrogenation at 100-140 °C, the total pressure required is very harsh, usually 1000 atm (Robert B. Anderson, in "The Fischer-Tropsch synthesis", pp.104 -105, Academic Press, 1984), the molecular weight of the product obtained is very large, and most of them are polyethylene greater than 10000

Embodiment 1

[0023] 73mg RuCl 3 ·nH 2 O and 620mg of polyvinylpyrrolidone (polyvinylpyrrolidone: Ru=20, molar ratio, the same below) were added to 20ml of water, stirred and mixed, and then added to a 60ml autoclave at 150°C, 20atm H 2 The catalyst for the reaction was obtained by reducing it for 2 hours. The prepared ruthenium nanoparticles have an average particle size of 1.8±0.4nm, and the transmission electron micrographs and particle size distribution of the ruthenium nanoparticles are shown in Figure 1a and Figure 1b, respectively.

[0024] Cool the catalyst to room temperature, release residual gas, and then fill with 10atm CO, 20atm H 2 , react at 150°C. The reaction results are shown in Table 1.

Embodiment 2

[0026] 73mg RuCl 3 ·nH 2 O and 106mg of polyvinylpyrrolidone (polyvinylpyrrolidone: Ru=3.4) were added to 20ml of 1,4-dioxane, stirred and mixed, and then added to a 60ml autoclave at 150°C, 20atmH 2 The catalyst for the reaction was obtained by reducing it for 2 hours. Cool to room temperature, release residual gas, fill with 10atmCO, 20atmH 2 , react at 150°C. The reaction results are shown in Table 1.

Embodiment 3

[0028] 73mg RuCl 3 ·nH 2 O and 106mg of polyvinylpyrrolidone (polyvinylpyrrolidone: Ru=3.4) were added to 20ml of ethanol, stirred and mixed, and then added to a 60ml autoclave at 150°C, 20atmH 2 The catalyst for the reaction was obtained by reducing it for 2 hours. Cool to room temperature, release residual gas, fill with 10atm CO, 20atm H 2 , react at 150°C. The reaction results are shown in Table 1.

Abstract

A transition metal nano-catalyst dedicated for Fischer-Tropsch synthesis reaction is prepared from the transition metal nanoparticles and high-molecular stabilizer through dispersing the transition metal nanoparticles in liquid medium to form colloid. A process for the Fischer-Tropsch synthesis reaction features the catalytic reaction between CO and H2 at low temp (100-200 deg.C) under the action of said nano-catalyst which has high low-temp activity.

Description

technical field [0001] The invention relates to a method for Fischer-Tropsch synthesis reaction and a special catalyst thereof. Background technique [0002] The Fischer-Tropsch synthesis reaction refers to the reaction in which carbon monoxide and hydrogen (synthesis gas) are converted into hydrocarbons under the catalysis of iron, cobalt, ruthenium and other metals. The product distribution is very wide, ranging from C 1 (methane) began to show a continuous distribution. Due to the depletion of petroleum resources, and the relative abundance of coal, natural gas, biomass and other resources, the production of syngas from coal, natural gas, biomass, etc., and then the synthesis of hydrocarbons (gasoline, diesel, etc.) from the syngas through Fischer-Tropsch synthesis can alleviate the The dependence on oil resources is of great significance to national security and social interests. [0003] At present, under the existing Fischer-Tropsch synthesis reaction conditions, the...
