Embodiment 1

[0053] Take 500g of pseudo-boehmite powder produced by Catalyst Changling Branch, add 20.0g of methyl cellulose, 15.0g of scallop powder and 475mL of deionized water, fully stir and mix evenly, after kneading evenly by extruder, extrude to form A wet form of aluminum hydroxide is obtained. Place the wet aluminum hydroxide molding in an oven at 150°C for 12 hours to dry. Vector Z1 is obtained. The radial crushing strength, water absorption rate and δ value (strength loss rate) of the molded carrier after drying were measured, and the results are listed in Table 1.

Embodiment 2

[0055] Take 250g of pseudo-boehmite powder produced by Catalyst Changling Branch, 250g of self-made amorphous aluminum hydroxide powder, add 10.0g of methylcellulose, 15.0g of hydroxyethylmethylcellulose and 475mL of deionized water, fully stir and mix Uniform, after being kneaded evenly by extruder, extruded to obtain wet molding of aluminum hydroxide. Place the wet aluminum hydroxide molding in an oven at 220°C to dry for 6 hours. Vector Z2 is obtained. The radial crushing strength, water absorption rate and δ value of the molded carrier after drying were measured, and the results are listed in Table 1.

Embodiment 3

[0057] Take 300g of pseudo-boehmite powder produced by Catalyst Changling Branch, 200g of aluminum hydroxide trihydrate, add 5.0g of methylcellulose, 10.0g of hydroxypropylmethylcellulose, 15.0g of turmeric powder and 475mL of deionized water , fully stirred and mixed evenly, after being kneaded evenly by an extruder, extruded to obtain a wet molded product of aluminum hydroxide. Place the wet aluminum hydroxide molding in an oven at 80°C for 12 hours to dry. Vector Z3 was obtained. The radial crushing strength, water absorption rate and δ value of the molded carrier after drying were measured, and the results are listed in Table 1.

Abstract

The invention relates to a ruthenium-containing Fischer-Tropsch synthesis catalyst, preparation and an application thereof. The catalyst comprises a carrier and a ruthenium metal component loaded on the carrier, wherein the ruthenium content (calculated as metal) is 0.1-15.0 wt% and the carrier content (calculated as alumina) is 85.0-99.9 wt% through adopting the catalyst as the reference, and the carrier is a forming composition containing hydrated alumina. Compared with the catalyst prepared by using the method in the prior art, the catalyst composition of the present invention has excellent Fischer-Tropsch synthesis performances, and is determined by the preparation method. In addition, the preparation method is simple, and a production cost of the catalyst of the present invention is significantly lower than a production cost of the catalyst prepared through the existing method.

Description

technical field [0001] The invention relates to a catalyst for Fischer-Tropsch synthesis and its preparation and application. Background technique [0002] In the 1930s, Fischer-Tropsch (FT or F-T) synthesis was first industrialized in Germany, and then similar synthetic oil plants were established in the United States, France, the former Soviet Union, and China. After World War II, the cost of synthetic oil due to this route was relatively high , Benefits can not compete with oil and closed down one after another, only South Africa developed coal-to-oil Fischer-Tropsch synthesis technology (Fischer-Tropsch synthesis process of Sasol Company) according to its national conditions rich in coal resources is still developing and improving. In the 1970s, the Dutch Shell company started the research on Fischer-Tropsch synthesis. The cobalt catalyst they developed was put into production in Malaysia in 1993. In recent years, with the increasing shortage of petroleum resources, ris...
