METHOD OF PREPARING CATALYST FOR PRODUCING DRILLING MUD COMPONENT, CATALYST AND METHOD OF PRODUCING DRILLING MUD COMPONENT Russian patent published in 2015 - IPC B01J21/12 B01J29/06 B01J37/04 B01J37/08 C10G50/00 C07C2/08 

FIELD: chemistry.

SUBSTANCE: invention relates to a method of preparing a catalyst for producing a component of environmentally safe hydrocarbon-based drilling mud, having a boiling range of 188-304°C according to ASTM D 86, which includes preparing a paste from gel obtained by mixing boehmite Pural SB with a mixture of nitric acid and distilled water, triethylene glycol and zeolite HY with molar ratio SiO₂/AlO₃ equal to 30 or 60, the porous structure of which is a system of interconnected straight channels formed by 12-member rings with diameter of the entrance window of 7E, extrusion, holding at room temperature for 9-10 hours, drying, grinding to particle size of 2-4×2 mm and calcining. The invention also relates to a catalyst for producing a component of environmentally safe hydrocarbon-based drilling mud and a method of producing said component.

EFFECT: simple technique, low cost of production while maintaining physical and chemical properties and improved performance in a wide temperature range, cetane number of not more than 45, and complete absence of aromatic, amine- and sulphur-containing compounds.
