A slurry hydrocracking, hydrotreating, and hydroisomerization route balances aromatic and n-paraffin content for renewable jet fuel.

Hydrogenation reforming upgrades pyrolysis gas from biomass or waste, cutting oxygen, water, and acids before condensation to recover cleaner oil.

Upstream fractionation separates renewable diesel cuts before isomerization and hydrocracking, boosting jet fuel yield while limiting over-cracking.

Adding an aromatic stream into the MTG catalyst bed boosts transalkylation, raises gasoline yield and octane, and lowers durene levels.

Diluting highly olefinic pyrolysis oil with recycled saturated effluent tempers reactor exotherm, improving control and catalyst life.

Heavy-fraction recycle to hydrocracking raises renewable kerosene and diesel yield while keeping cold-flow and boiling-range specifications in check.

Hydrotreating the full Fischer-Tropsch tail gas converts alkenes to alkanes without gas separation, cutting alkene content below 1%.

Separating impurities by centrifugation, distillation, and solvent extraction prepares waste lubricant for hydrocracking into high-grade base oil.

Converting iso-paraffins to normal paraffins in hydrogen-enriched liquid feed improves ethylene and propylene yield.

A fractionator routes C8–18 material to isomerization and C18+ material to hydrocracking, then recycles product to limit drag loss.
