Processes herein may be used to thermally crack various hydrocarbon feeds, and may eliminate the refinery altogether while making the crude to chemicals process very flexible in terms of crude. In embodiments herein, crude is progressively separated into light and heavy fractions utilizing convection heat from heaters used in steam cracking. Depending on the quality of the light and heavy fractions, these are routed to one of three upgrading operations, including a fixed bed hydroconversion unit, a fluidized catalytic conversion unit, or a residue hydrocracking unit that may utilize either an ebullated bed reactor with extrudate catalysts or a slurry hydrocracking reactor using a homogeneous catalyst system, such as a molybdenum based catalysts which may optionally be promoted with nickel. Products from the upgrading operations can be finished olefins and/or aromatics, or, for heavier products from the upgrading operations, may be used as feed to the steam cracker.

The invention relates to C.sub.5+ hydrocarbon conversion. More particularly, the invention relates to separating a vapor phase product and a liquid phase product from a heated mixture that includes steam and C.sub.5+ hydrocarbons, catalytically cracking the liquid phase product and steam cracking the vapor phase product.

The present disclosure relates to methods for preparing aviation fuel component from a feedstock containing fossil hydrotreating feed and a second feed containing esters of fatty acids and rosins, free fatty acids and resin acids. The method includes subjecting the feedstock to hydrotreatment reaction conditions to produce a hydrotreated stream, separating the hydrotreated stream to three fractions from which at least part the highest boiling fraction is subjected to hydrocracking reaction to produce a hydrocracked stream. At least part of the hydrocracked stream is admixed with at least part of the hydrotreated stream, and their admixture is processed further until desired conversion of the feedstock to the aviation fuel component is obtained.

Disclosed is a method for maximizing ethylene or propene production, the main steps thereof being: taking crude oil and distillate thereof, pre-processing urban mixed-waste plastics as raw material, then entering same into a catalytic cracking reactor, removing via a two-stage pre-wash tower and related separation, then cooling the reacted high-temperature oil and gas and removing impurities to obtain light and heavy distillate oils; performing a hydrogenation reaction operation on the heavy distillate oil; performing light distillate oil separation, performing a recombination operation on its olefins, its alkanes entering a steam cracking apparatus to produce rich ethylene, and its aromatic components being separated as by-products; the product of the described hydrogenation and recombination reaction and the steam-cracked distillate oil is recycled to the catalytic cracking reactor. In the production method of the present invention, the yield of ethylene and propene together is 45-75 m % of the raw material, and the yield of aromatics is 15-30 m % of the raw material; in particular, when using urban mixed-waste plastics as raw material, the ethylene or propene thus produced are used to produce new plastics by way of a conventional polymerization process, achieving the chemical recycling of waste plastics.
