摘要:
The invention relates to a process for hydroconversion of heavy carbon-containing feedstocks that comprises a stage (1) for hydroconversion of the feedstock in at least one reactor that contains a boiling-bed catalyst and then a stage (2) for hydroconversion of at least a portion of the effluent that is obtained in at least one reactor that contains a slurry catalyst.
摘要:
The present invention describes a reaction zone comprising at least two fluidized reactors, a principal reactor for cracking a heavy hydrocarbon cut, the other, additional, reactor for cracking one or more light cuts, the effluents from the two reactors being treated in a common gas-solid separation and quench zone. Performance is enhanced because the thermal degradation reactions in the reaction zone are controlled in an optimum manner.

Conversion of a heavy hydrocarbon fraction that is obtained either from a crude oil or from the distillation of a crude oil and that has an initial boiling point of at least 300° C. by hydroconversion of at least one portion of heavy hydrocarbon fraction in the presence of hydrogen in at least one three-phase reactor containing at least one hydroconversion catalyst, separation of the effluent to obtain a light liquid fraction that boils at a temperature that is less than 300° C. and a heavy liquid fraction that boils at a temperature that is greater than 300° C., and a deasphalting of at least one portion of the heavy liquid fraction that boils at a temperature that is greater than 300° C.

For conversion of crude oil or a heavy hydrocarbon fraction having an initial boiling point of at least 300° C., conducting a catalytic hydroconversion in a three-phase reactor operating in a boiling bed with an upward flow of liquid and gas, separating resultant effluent into a light liquid fraction boiling at less than 300° C. and a heavy liquid fraction boiling above 300° C., deasphalting the heavy liquid fraction to obtain a deasphalted hydrocarbon fraction and residual asphalt, and recycling at least one portion of the deasphalted hydrocarbon fraction upstream of the hydroconversion stage.
摘要:
The invention relates to a method for treating a hydrocarbons charge comprising the following stages, in which: a) the charge is brought into contact with a solvent in order to obtain a deasphalted effluent having a content of asphaltenes below 3000 ppm by weight, b) the deasphalted effluent is cracked in the presence of hydrogen and a hydrocracking catalyst, in a bubbling-bed reactor, so as to convert at least 50 wt. % of the fraction of the deasphalted effluent boiling above 500° C. to compounds having a boiling point below 500° C., c) the effluent from stage b) is fractionated to recover gasolines, kerosene, gas oils and a first residue, and d) at least a portion of this first residue is cracked so as to obtain an effluent comprising gasolines, kerosene, gas oils and a second residue.
摘要:
Process for hydrotreating a heavy hydrocarbon fraction using a system of switchable fixed bed guard zones each containing at least one catalyst bed including at least one step during which the flow of feed supplied to the first guard zone brought into contact with the feed is partly displaced to the next guard zone downstream, preferably progressively.

摘要:
The invention relates to a method of hydroconverting in ebullated bed mode a petroleum feed containing a significant amount of light fractions and, among other things, asphaltenes, sulfur-containing and metallic impurities.More precisely, the object of the invention is a hydroconversion method using at least one ebullated-bed reactor for which injection of the feed is carried out at the top of said reactor, in the gas overhead, and involving separation within said feed inside the reactor into a vaporized fraction and a liquid fraction.The invention also relates to the reactor allowing said method to be implemented.
