Dynamics of Silicon Sorption on the NiMo/Al2O3 Guard Bed Catalyst During Hydrotreating of Diesel
Abstract
The dynamics of the silicon sorption on the NiMo/Al2O3 guard-bed catalyst containing ~2.0 wt % Ni and ~6.0 wt % Mo during hydrotreating of diesel was studied. The catalyst bed was divided into five equal sections separated by perforated metal partitions permeable to the feed. Four series of experiments were performed; their time was varied in the range 48–200 h, and the temperature was 340°C. A diesel fraction containing ~1.0 wt % sulfur, 130 ppm nitrogen, and 200 ppm silicon introduced in the form of decamethylcyclopentasiloxane was used as the feed. The specific surface area of all the spent samples was 170–190 m2/g, the pore volume was 0.35– 0.43 cm3/g, and the average pore diameter was 8–9 nm. The sorption on a catalyst grain 2.5 mm in diameter is diffusion-controlled. The effective mass transfer coefficient and the catalyst capacity under the experimental conditions (5 wt %) were estimated using the equation describing the sorption process.
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.
