Distillates are prepared from asphaltenes-rich feeds by a process comprising subjecting the feed to thermal cracking, and subjecting the distillation residue of the cracked product to a combination of solvent deasphalting and catalytic hydroconversion.

Process for the preparation of hydrocarbon oil distillates

A process is disclosed for the conversion of asphaltines-containing mineral hydrocarbon oil to distillate gas oil by a processing sequence comprising thermal cracking, flashing, atmospheric fractionation, vacuum fractionation, thermal cracking, catalytic cracking or hydrocracking, and atmospheric fractionation with certain recycle of intermediate streams to achieve efficient, economic operations.

Process for the preparation of gas oil

A process for the preparation of gas oil from residual oils by combination of two stages of thermal cracking, cyclone separation, vacuum distillation, deasphalting, atmospheric distillation, and recycling of certain streams.

A process for preparing light distillate fractions and medicinal oil from heavy hydrocarbon oils comprises two-stage hydrocracking, fractionation distillation and catalytic hydrotreatment of at least part of the fractionation residue.

Process for preparing hydrocarbons

Process for treatment of tars and oil, the process being characterized by distillation of the oil to form a vacuum distillate and vacuum residue, hydrocracking of the distillate, deasphalting of the residue, and hydrodemetallizing and hydrodesulphurizing the deasphalted residue.

Process for the preparation of synthetic crude oil

A process is disclosed for 'in-situ' fluoriding of catalyst in a fixed bed wherein an amount of a fluorine is provided which is in excess by at least an average of 10%w of the amount of fluorine absorbed by the catalyst resulting in more efficient, uniform catalyst.
