A method for producing a low-viscosity high-aromatic non-carcinogenic petroleum-based process oil which can be used as a plasticizer oil or an extender oil in the manufacture of synthetic rubber and tyres is described. The oil is obtained from by-product fractions of secondary petrochemical processes by fractional distillation, wherein the used by-product fractions of secondary petrochemical processes are products of catalytic cracking, or products of catalytic reforming, or aromatic extracts, or mixtures thereof, which have an initial boiling point of no less than 200° C. and above and a final boiling point of no less than 360° C. at atmospheric pressure, and contain no less than 85% of aromatic constituents and no more than 10.0 mg/kg of the sum of the following polycyclic aromatic hydrocarbons: benz[a]anthracene; chrysene; benzo[b]fluoranthene; benzo[i]fluoranthene; benzo[k]fluoranthene; benzo[e]pyrene; benzo[a]pyrene; and dibenzo[a,h]anthracene.

The present disclosure is directed to methods of producing zincoaluminosilicate structures with AEI, CHA, and GME topologies using organic structure directing agents (OSDAs), and the compositions and structures resulting from these methods.

A two-step process that includes a pyrolytic first step carried out in a mechanically or gravitationally impelled reactor and a catalytic fluid bed second step that upgrades the resulting vapor, for the conversion of waste plastics, polymers, and other waste materials to useful chemical and fuel products such as paraffins, olefins, and aromatics such as BTX is described.

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 present invention pertains to improved processes and catalysts for aromatization. The processes generally contacting a feed stream comprising a naphtha fraction having a C.sub.6 to C.sub.8 content with a catalyst pellet composition to form aromatic hydrocarbons. The catalyst pellet composition generally comprises a plurality of cylindrical pellets each pellet comprising a Group VIII metal on a zeolite. The pellets may have (a) a plurality of holes passing through the length of the cylindrical pellets, (b) a dome-shaped top and bottom, and (c) a plurality of semi-circular grooves along the length of the exterior of the cylinder.

Methods for catalytic cracking hydrocarbon mixture have been disclosed. A hydrocarbon mixture having an initial boiling temperature of 30° C. to 70° C. is catalytically cracked in the presence of a catalyst to produce one or more olefins and/or one or more aromatics. The catalytic cracking is conducted such that the amount of coke formed on the catalyst is at least 5 wt. % (based on total weight of spent catalyst). The catalyst from the catalytic cracking step is then regenerated to produce regenerated catalyst.

A processing facility is provided that includes a feedstock separation system configured to separate a feed stream into a lights stream and a heavies stream, a hydrogen production system configured to produce hydrogen and carbon dioxide from the lights stream, and a carbon dioxide conversion system configured to produce synthetic hydrocarbons or the carbon dioxide. The processing facility also includes a hydroprocessing system configured to process the heavies stream, and a hydroprocessor separation system configured to separate a hydroprocessing system effluent into a separator tops stream and a separator bottoms stream, wherein the separator bottoms stream is fed to the hydrogen production system.

A process for converting pyrolysis effluent stream into hydrocarbon products. Waste plastics are pyrolyzed at high temperature in a pyrolysis reactor to obtain a plastic pyrolysis effluent stream. The plastic pyrolysis effluent stream is further sent to a steam cracking unit for the separation of plastic pyrolysis effluent stream into a C5+ hydrocarbon stream and a C4 hydrocarbon stream. The pyrolysis reactor is operated at a to obtain hydrocarbon products of high value.
