Influence of the Structural Type of Zeolites on the Physicochemical and Catalytic Properties of NiMo Sulfide Catalysts in the Hydrotreating of Triglyceride Feedstock
NiMo sulfide catalysts supported on zeolites of various structural types were prepared by incipient wetness impregnation. The materials, supports, and catalysts based on them were characterized by low-temperature nitrogen adsorption, energy-dispersive X-ray fluorescence analysis, Fourier IR spectroscopy of adsorbed pyridine, and transmission electron microscopy. The catalytic properties of the systems in the hydrodeoxygenation/hydroisomerization of the triglyceride feedstock were studied using a fixed-bed flow-through reactor at T = 280–340°С, P = 4 MPa, hydrogen to feed ratio H/F of 600 nl/l, and liquid hourly space velocity LHSV of 1–2 h–1. For all the catalytic systems irrespective of the support type, the degree of deoxygenation reaches 100%, and at T = 320°С and LHSV = 1 h–1 the relative content of alkane isomerization products decreases in the order NiMoS/A (SiO2/Al2O3 = 30) > NiMoS/B (SiO2/Al2O3 = 300) > NiMoS/D (SiO2/Al2O3 = 30) > NiMoS/C (SiO2/Al2O3 = 48).
期刊介绍：
Petroleum Chemistry (Neftekhimiya), founded in 1961, offers original papers on and reviews of theoretical and experimental studies concerned with current problems of petroleum chemistry and processing such as chemical composition of crude oils and natural gas liquids; petroleum refining (cracking, hydrocracking, and catalytic reforming); catalysts for petrochemical processes (hydrogenation, isomerization, oxidation, hydroformylation, etc.); activation and catalytic transformation of hydrocarbons and other components of petroleum, natural gas, and other complex organic mixtures; new petrochemicals including lubricants and additives; environmental problems; and information on scientific meetings relevant to these areas.
Petroleum Chemistry publishes articles on these topics from members of the scientific community of the former Soviet Union.
