According to one or more embodiments described herein, a method for processing a hydrocarbon feedstock may include contacting a mixed feed with a solvent in a deasphalting system to form residue and deasphalted oil, contacting the deasphalted oil with supercritical water to form an upgraded oil, separating the upgraded oil into at least a light fraction and a heavy fraction, and combining at least a portion of the heavy fraction with the hydrocarbon feedstock to form the mixed feed.

Provided is a system for continuous processing of heavy fuel oil from recycling waste oil and the processing residues of crude oil into useful products including means for feeding waste oil; at least one hot-gas filter, at least one condenser, at least one rotating kiln including an outer stationary jacket which forms a heating channel, and an inner rotating reactor, and means for removing solid coke from the rotating reactor. The at least one hot gas filter is configured to separate a naphtha/gasoil fraction after the processing of the heavy fuel oil from a soft coke fraction. The rotating reactor is configured to recover a solid coke fraction comprising high contaminant content. The invention further relates to a process for continuous processing of heavy fuel oil from recycling waste oil and the processing residues of crude oil into useful products, preferably with the system of the invention. Moreover, the invention relates to use of the products and waste products produced with the process and system of the invention.

The present invention is based on the use of a two-step hydrocracking process for the production of naphtha, comprising a step of hydrogenation placed downstream of the second hydrocracking step, the hydrogenation step treating the effluent resulting from the second hydrocracking step in the presence of a specific hydrogenation catalyst. Furthermore, the hydrogenation step and the second hydrocracking step are performed under specific operating conditions and in particular under quite specific temperature conditions.

Systems and processes are disclosed for producing petrochemical products, such as ethylene, propene and other olefins from crude oil in high severity fluid catalytic cracking (HSFCC) units. Processes include separating a crude oil into a light fraction and a heavy fraction, cracking the light fraction and heavy fraction in separation separate cracking reaction zones, and regenerating the cracking catalysts in a two-zone having a first regeneration zone for the first catalyst (heavy fraction) and a second regeneration zone for the second catalyst (light fraction) separate from the first regeneration zone. Flue gas from the first catalyst regeneration zone is passed to the second regeneration zone to provide additional heat to raise the temperature of the second catalyst of the light fraction side. The disclosed systems and processes enable different catalysts and operating conditions to be utilized for the light fraction and the heavy fraction of a crude oil feed.

This disclosure relates to a procedure, which through the application of a catalyst in homogeneous phase, allows the transformation of heavy hydrocarbons (vacuum residue, atmospheric residue, heavy and extra-heavy crudes) into hydrocarbons of lower molecular weight, characterized because after its application, the hydrocarbons obtain greater API gravity, lower kinematic viscosity and different composition by hydrocarbon families (SARA) that increases the proportion of saturated and aromatic resins and asphalts. The sulphur and nitrogen content is also reduced, resulting in higher yields to high commercial value distillates and a lighter product as compared to the original crude.

The present invention relates to a process for deparaffinning a middle distillate feedstock, to convert, in good yield, feedstocks having high pour points into at least one cut having an improved pour point.

Said process is performed with at least one catalyst comprising at least one hydro-dehydrogenating phase containing at least one metal from group VIB and at least one metal from group VIII of the Periodic Table of the Elements, and a support comprising at least one IZM-2 zeolite, a zeolite of WI framework type code and at least one binder.

Integrated processes and systems for the production of distillate hydrocarbons and coke. The process may include feeding a hydrocarbon feedstock, comprising a residuum hydrocarbon fraction, to a residue hydrocracking reactor system to convert hydrocarbons therein, producing a hydrocracked effluent. The hydrocracked effluent may then be fed to a separation system, separating the hydrocracked effluent into one or more distillate hydrocarbon fractions and a vacuum residue fraction. The vacuum residue fraction may be fed to a coker system, converting the vacuum residue fraction into a coke product and a coker vapor effluent, recovering the coke product, and feeding the coker vapor effluent to the separation system. The one or more distillate hydrocarbon fractions are hydroprocessed to produce a hydroprocessed effluent, and the hydroprocessed effluent is separated into product distillate hydrocarbon fractions.

Embodiments of the disclosure provide an aqueous reforming system and a method for upgrading heavy hydrocarbons. A hydrocarbon feed and a surfactant stream are combined to produce a first precursor stream. The first precursor stream and an alkali feed are combined to produce a second precursor stream. The second precursor stream and a transition metal feed are combined to produce a catalytic emulsion stream. The catalytic emulsion stream is heated to produce a catalytic suspension and a decomposition gas, where the decomposition gas is separated by a first separator. The catalytic suspension is combined with a preheated water stream to produce an aqueous reformer feed. The aqueous reformer feed is introduced to an aqueous reformer such that the heavy hydrocarbons undergo conversion reactions to produce an effluent stream. The effluent stream is introduced to a second separator to produce a heavy stream and a light stream. The light stream is introduced to a third separator to produce a gas stream, a distillate stream, and a spent water stream. Optionally, a portion of the distillate stream and the hydrocarbon feed can be combined to produce the first precursor stream such that the first precursor stream is in the absence of a surfactant.

Marine diesel fuel/fuel blending component compositions and fuel oil/fuel blending component compositions are provided that are derived from crude oils having high naphthenes to aromatics volume and/or weight ratios and a low sulfur content. In addition to having a high naphthenes to aromatics ratio, a low sulfur content, and a low but substantial content of aromatics, such fuels and/or fuel blending components can have a reduced or minimized carbon intensity relative to fuels derived from conventional sources. The unexpected ratio of naphthenes to aromatics contributes to the fuels and/or fuel blending components further having additional unexpected properties, including low density, low kinematic viscosity, and/or high energy density.

The present disclosure provides an integrated method and apparatus for catalytic cracking of heavy oil and production of syngas. A cracking-gasification coupled reactor having a cracking section and a gasification section is used as a reactor in the method. A heavy oil feedstock is fed into a cracking section to contact with a bed material in a fluidized state that contains a cracking catalyst, a catalytic cracking reaction is conducted under atmospheric pressure to obtain light oil-gas and coke. The coke is carried downward by the bed material into a gasification section to conduct a gasification reaction to generate syngas; the syngas goes upward into the cracking section to merge with the light oil-gas, and is guided out from the coupled reactor and enter a gas-solid separation system. Oil-gas fractionation is performed to a purified oil-gas product output from the gas-solid separation system to collect light oil and syngas products.
