Hydrocracking of residual oil using molybdenum supported over mesoporous alumina as a catalyst. Chemical Engineering Journal , , DOI: . heavy oils, bitumen, de-asphalter bottoms, visbroken tars, coal liquids) showing high flexibility and resistance to the contamination (e.g. from metals, asphaltenes, sulphur, nitrogen)8. The slurry phase hydrocracking of vacuum residue was investigated by Kim et al9. The experimental conditions varied in a wide range of temperature, pressure, andFile Size: 1MB. Abstract. Residue hydrocracking has been attracting more and more attention to the refining industry in recent years, and one of the best approaches is ebullated bed residue hydrocracking (EBRH). STRONG ebullated bed residue hydrocracking uses a new type of reactor, and a 50 KTA demonstration unit has been put into operation by: 1. Comparing the type distribution in each product, it is suggested that, with the use of Al 2 O 3-B 2 O 3 catalyst, main reaction of TK-AR hydrocracking was the hydroconversion of aromatics in feedstock to saturates and naphthenic compounds in gas oil, while USY catalyst converted all types in residual oil to naphtha, kerosene and gas oil Cited by: 6.
Residual oil fairways. Similar residual oil targets also occur in many hydrocarbon basins in so-called residual oil zone fairways, which have recently been investigated as a potential new type of geological storage target. Residual oil fairways occur within saline aquifers on the paths along which oil migrated over geological time before reaching current oil reservoirs. In this article, we will focus on cocurrent downflow, which, because of its relatively lower pressure drop and the absence of flooding, is by far the most common mode of operation in industrial practice. Trickle-bed reactors are used primarily in the petroleum industry for hydrocracking, hydrodesulfurization. hydrocracking, hydrovisbreaking, donor-solvent processes. 2. Carbon rejection processes: coking, visbreaking, and other processes such as solvent deasphalting. Both hydrogen addition and carbon rejection processes have disadvantages when applied to upgrade heavy oils or residua. For instance, removal of nitrogen, sulfur andFile Size: KB. hydrocracking Hydrocracking Severe form of hydroprocessing •Break carbon‐carbon bonds •Drastic reduction of molecular weight Reduce average molecular weight & produce higher yields of fuel products 50%+ conversion Products more appropriate for diesel than gasoline 5File Size: 2MB.
Many oil refineries employ hydroprocessing for removing sulfur and other impurities from petroleum feedstocks. Capable of handling heavier feedstocks than other refining techniques, hydroprocessing enables refineries to produce higher quality products from unconventional- and formerly wasted- by: Purchase Hydrotreatment and Hydrocracking of Oil Fractions, Volume - 1st Edition.
