A process for prolonging catalyst activity may comprise contacting heavy hydrocarbon feedstock, wherein the heavy hydrocarbon feedstock is essentially free of residue, and hydrogen with catalyst in a hydroprocessing unit operating at a pressure of greater than or equal to 100 bars. The process may further comprise performing hydrocracking, hydrodesulfurization, and hydrodenitrogenation in a single stage of the hydroprocessing unit to create a hydroprocessed effluent. The process may further comprise regenerating spent catalyst in a catalyst regeneration unit. Additionally, the process may further comprise passing regenerated catalyst back to the hydroprocessing unit without rejuvenating the spent catalyst.

A process for hydroconversion-distillation of heavy and/or extra-heavy crude oils, which comprises four stages: 1) desalting and separation of the feedstock; 2) catalytic hydrotreating of light fraction (optional); 3) catalytic hydroconversion of heavy fraction, and 4) distillation of hydrotreated products
to provide products that can be processed in conventional refining schemes designed to operate with light and intermediate crude oils.

Aromatic extraction and hydrocracking processes are integrated to optimize the hydrocracking units design and/or performance. By processing aromatics-rich and aromatic-lean fractions separately, the hydrocracking operating severity and or catalyst reactor volume requirement decreases.

Processes for upgrading resid hydrocarbon feeds are disclosed. The upgrading processes may include: hydrocracking a resid in a first reaction stage to form a first stage effluent; hydrocracking a deasphalted oil fraction in a second reaction stage to form a second stage effluent; fractionating the first stage effluent and the second stage effluent to recover at least one distillate hydrocarbon fraction and a resid hydrocarbon fraction; feeding the resid hydrocarbon fraction to a solvent deasphalting unit to provide an asphaltene fraction and the deasphalted oil fraction.

The present disclosure provides a versatile process for producing valuable renewable hydrocarbons from triglyceride containing feedstock. The triglyceride containing feedstock is first split to provide a mixture containing fatty acids, glycerol and water, from which a phase separation provides an oily phase, and an aqueous phase. The oily phase containing fatty acids is subjected to fractionation, whereby specific fractions may be refined to products with controlled hydroprocessing. Products may contain paraffinic renewable aviation fuel components, paraffinic renewable base oil, renewable paraffinic diesel fuel components, renewable paraffinic technical fluid, or any combination thereof.
