| titleOfInvention | Method of using a catalyst for hydrogenating diolefins during hydrogenation treatment of petroleum feedstock |
| abstract | FIELD: oil and gas industry.SUBSTANCE: invention relates to methods of using a catalyst for hydrogenating diolefins during hydrogenation treatment of petroleum feedstock and can be used in oil refining industry. Disclosed is a method of using a catalyst for hydrogenating diolefins in a hydrogenation treatment of petroleum feedstock, wherein the material is passed through a fixed catalyst bed of a catalyst stack consisting of a basic hydroprocessing catalyst, in form of aluminum-nickel-molybdenum and / or aluminum-cobalt-molybdenum catalyst and protective layers arranged above it. Protective layers include: layer A – inert material for removal of mechanical impurities, layer B – catalyst for hydrogenation of diolefins, consisting of modified carrier prepared on the basis of highly porous cellular material with mesh of 10–30 mesh, grafted layer of gamma-aluminum oxide, as well as bimetallic complex compounds of VIII and VI groups metals deposited on the support. Method is characterized by using layer B catalyst prepared on the basis of highly porous cellular material with open porosity of not less than 50 %, having the shape of discs with diameter of 20–50 mm, height of 20–30 mm, in activated state having specific surface of 12–25 m/g, effective pore diameter of 3–6.7 nm, mesh content of 10–30 mesh, mechanical compression strength of not less than 200 N, wherein content of components in calcined at temperature of 550 °C layer B catalyst is, wt%: high-porous cellular material – 73.0–88.1; γ-AlOin the form of grafted layer – 8.0–22.2; nickel and / or cobalt oxide – not less than 0.5; molybdenum oxide – not less than 2.0. Protective layers additionally include layer B – aluminum-nickel-molybdenum or aluminum-molybdenum catalyst of protective layer located under layers A and B, protective layers making 15–25 % of volume of reactor, and content of layer B makes 27–65 vol% of catalysts of protective layers.EFFECT: method of using a catalyst for hydrogenation of diolefins during batch loading in the process of complex hydrotreatment of hydrocarbon material, which enables to achieve absence of diolefins in hydroforming products.3 cl, 2 tbl |
