摘要:
A Fischer-Tropsch synthesis reaction catalyst includes a catalyst support containing a silica and zirconium oxide in an amount of 0.5 to 14% by mass based on the mass of the catalyst support, and cobalt metal and a cobalt oxide supported on the catalyst support in an amount equivalent to 10 to 40% by mass of tricobalt tetroxide based on the mass of the catalyst, wherein the degree of reduction of the cobalt atoms is within a range from 75 to 93%, and the amount of hydrogen gas adsorption per unit mass of the catalyst at 100°C is within a range from 0.40 to 1.0 ml/g.
摘要:
A method for producing an aviation fuel oil base, including: a first step of obtaining a first generated oil by hydrotreating a feedstock by bringing a feedstock which includes an oxygen-containing hydrocarbon compound derived from an animal or vegetable oils and fat into contact with a first dual functional catalyst which has dehydrogenation and hydrogenation functions and which includes a metal of group 6A of the periodic table, a metal of group 8, and an amorphous solid acidic substance, in the presence of hydrogen; and a second step of obtaining a second generated oil including an aviation fuel oil base by hydroisomerizing the first generated oil by bringing the first generated oil into contact with a second dual functional catalyst which has dehydrogenation and hydrogenation functions and which includes a metal of the group 8 of the periodic table and a crystalline solid acidic substance, in the presence of hydrogen.
摘要:
A method for producing a lubricant base oil, comprising: a first step of contacting a feedstock containing normal paraffins having not less than 20 carbon atoms with a first catalyst in the presence of molecular hydrogen to obtain a first produced oil, and a second step of contacting the first produced oil with a second catalyst in the presence of molecular hydrogen to obtain a second produced oil, wherein the first catalyst comprises a first carrier in which a fraction of an amount of NH 3 to be desorbed at 300 to 800°C based on a total amount of NH 3 to be desorbed is 80 to 90% in temperature-programmed desorption of NH 3 , a first metal that is at least one selected from metals that belong to Group VI in the periodic table and is carried on the first carrier, and a second metal that is at least one selected from metals that belong to Group VIII to Group X in the periodic table and is carried on the first carrier; a sum C 1 + C 2 of a proportion C 1 of the first metal contained in the first catalyst in terms of an oxide (% by mass) and a proportion C 2 of the second metal contained in the first catalyst in terms of an oxide (% by mass) is 22 to 36% by mass; and a ratio D 1 /D 2 between a content of the second metal D 2 (mol) and a content of the first metal D 1 (mol) in the first catalyst is 1.07 to 7.78.
