摘要: Fuel oil compositions, and methods for blending such fuel oil compositions, to enhance initial compatibility and longer term stability when such fuel oil compositions are blended to meet IMO 2020 low sulfur fuel oil requirements (ISO 8217). In one or more embodiments, asphaltenic resid base stocks are blended with high aromatic slurry oil to facilitate initial compatibility such that low sulfur cutter stocks, e.g., vacuum gas oil and/or cycle oil, may be further blended therein to cut sulfur content while maintaining longer term stability. These fuel oil compositions are economically advantageous when used as marine low sulfur fuel oils because greater concentrations of high viscosity resids are present in the final blend.

摘要: A method is disclosed for reducing fouling in catalytic cracking. The method includes subjecting a recycled fossil-based feedstock to a heat treatment, evaporating the heat-treated feedstock, hydrotreating resulting evaporation distillate and performing catalytic cracking of the hydrotreated distillate in a presence of a solid acid catalyst.

摘要: A process for producing propylene and a low-sulfur fuel oil component, comprising the steps of: i) contacting a hydrocarbon-containing feedstock oil with a catalytic conversion catalyst for reaction under effective conditions in a catalytic conversion reactor in the absence of hydrogen to obtain a reaction product comprising propylene; ii) separating the reaction product from step i) to obtain a catalytic cracking distillate oil, and iii) subjecting the catalytic cracking distillate oil to hydrodesulfurization to obtain a low-sulfur hydrogenated distillate oil suitable for use as a fuel oil component. The process can greatly improve the propylene selectivity and propylene yield while producing more fuel oil components, significantly reduce the yield of dry gas and coke, and thus has better economic and social benefits.

摘要: According to one or more embodiments, petrochemical products may be formed from a hydrocarbon material by a method that includes separating crude oil into at least two or more fractions in an atmospheric distillation column, hydrotreating the atmospheric residue to form a hydrotreated atmospheric residue, combining steam with the hydrotreated atmospheric residue, and cracking at least a portion of the hydrotreated atmospheric residue in the presence of a first catalyst to produce a cracking reaction product.

摘要: The invention concerns a method for converting heavy hydrocarbon feedstocks of which at least 50% by weight boils at a temperature of at least 300° C., and in particular vacuum residues. The feedstocks are subjected to a first step a) of deep hydroconversion, optionally followed by a step b) of separating a light fraction, and a heavy residual fraction is obtained from step b) of which at least 80% by weight has a boiling temperature of at least 250° C. Said fraction from step b) or the effluent from step a) is then subjected to a second step c) of deep hydroconversion. The overall hourly space velocity for steps a) to c) is less than 0.1 h−1. The effluent from step c) is fractionated to separate a light fraction. The heavy fraction obtained, of which 80% by weight boils at a temperature of at least 300° C., is sent to a deasphalting step e). The deasphalted fraction DAO is then preferably converted in a step f) chosen from ebullated bed hydroconversion, fluidised bed catalytic cracking and fixed bed hydrocracking.

摘要: A method of producing a fuel additive includes: passing a first process stream comprising C4 hydrocarbons through a methyl tertiary butyl ether synthesis unit producing a first recycle stream; passing the first recycle stream through a hydration unit producing the fuel additive and a second recycle stream; passing the second recycle stream through a recycle hydrogenation unit and a deisobutanizer unit; and recycling the second recycle stream to the methyl tertiary butyl ether synthesis unit.

摘要: A method is disclosed for preparing an aviation fuel composition by subjecting a feedstock of biological and/or recycled origin to cracking in a cracking unit and to fractionation in a fractionation unit to obtain a kerosene fraction. The obtained kerosene fraction is subjected to hydrotreatment in a hydrotreatment unit to form a first jet fuel component. The formed first jet fuel component is mixed with a further jet fuel component to form a fuel composition having a wear scar diameter of 0.78 mm or less, as measured with BOCLE lubricity test method according to ASTM D5001. The feedstock contains one or more of tall oil pitch (TOP), a mixture of sludge palm oil, palm fatty acid distillate and animal fat (FATS), and used lubricant oil (ULO).

摘要: Methods for making higher-octane fuel components from a feed stream of C8+ paraffins, including catalytically cracking the C8+ paraffins using a Zeolite catalyst to produce a reaction product of mid-chain paraffins and olefins and short-chain paraffins and olefins. The reaction product comprises liquid phase paraffins having an increased Octane Value over the feed stream paraffins. The reaction product further comprises a gas phase of short-chain paraffins which are separated from the liquid phase. In embodiments, the short chain olefins are hydrogenated to form mid-chain paraffins and a gas phase containing short-chain paraffins.
