Problems solved by technology

For example, when the middle distillate is used for gas oil, if the n-paraffin content is high, the low-temperature fluidity will be poor, and in the worst case, the use as a commodity will be limited.

Embodiment 1

[0048] Then, 140 ml of the first catalyst and 60 ml of the second catalyst were stacked and filled in the fixed-bed reaction tower, and metal (platinum) was reduced at 345° C. for 4 hours under a hydrogen flow before the reaction. Then, at a liquid hourly space velocity of 2.5h relative to the raw materials of the 1st and 2nd catalyst overall -1 , under the condition of reaction pressure 4MPa, hydrogen / oil ratio 520NL / L, reaction temperature is set as 280 ℃, carries out the hydrogenation treatment of raw material, makes the cut (cleavage product) below boiling point 360 ℃ reach 80 mass % relative to raw material. The thus obtained product oil was analyzed by gas chromatography to determine the ratio (yield) of the middle distillate having a boiling point of 140 to 360°C in the cracked product and the normal paraffin content in the middle distillate. In addition, at the same time, for uncracked wax having a boiling point of 360° C. or higher, the normal paraffin content in the ...

Abstract

A method of hydrotreating a wax, characterized by bringing the wax in a hydrogen atmosphere into contact with a first catalyst (10) comprising ultrastable zeolite Y and an amorphous solid acid and then with a second catalyst (20) containing substantially no ultrastable zeolite Y and comprising a solid acid, under the conditions of a liquid hourly space velocity of 0.4-4.0 h<-1>, to thereby hydrotreat the wax.

Description

technical field [0001] The present invention relates to methods for hydrotreating waxes, and methods for producing fuel base materials and lubricating oil base materials. Background technique [0002] In recent years, expectations for liquid fuels with low sulfur and aromatic hydrocarbon contents have been increasing as environmentally friendly clean liquid fuels. One of the methods for producing such a clean liquid fuel is Fischer-Tropsch (FT) synthesis using hydrogen and carbon monoxide as raw materials. According to the FT synthesis method, waxes (FT waxes) can be produced in addition to alkane-rich and sulfur-free liquid fuel bases. The FT waxes are converted to middle distillates by hydrocracking, on the other hand, the uncracked wax fractions are converted to middle distillates by recycling, or by MEK dewaxing to remove n-paraffins into high performance lubricant bases. [0003] When the middle distillate is produced by hydrocracking of FT wax, a high yield is expect...
