CO-PROCESSING ROUTE FOR HYDROTREATING POLYMER WASTE-BASED MATERIAL
Provided is a method for upgrading polymer waste-based material. The method includes providing a polymer waste-based feedstock, providing a crude oil-derived feedstock, mixing the polymer waste-based feedstock, the crude oil-derived feedstock, and optionally a further feed material, to provide a feed mixture, hydrotreating the feed mixture in a FCC feed hydrotreater to provide a hydrocarbonaceous material, and recovering at least a distillate product and a distillation bottoms product from the hydrocarbonaceous material (step E).
Process and plant for producing hydrocarbons with reduced CO.SUB.2.-footprint and improved hydrogen integration
Process and plant for producing hydrocarbon products from a feedstock originating from a renewable source, where a hydrogen-rich stream and on off-gas stream comprising hydrocarbons is formed. A portion of the hydrogen-rich stream is used as a recycle gas stream in a hydroprocessing stage for the production of said hydrocarbon products, and another portion may be used for hydrogen production, while the off-gas stream is treated to remove its H.sub.2S content and used as a recycle gas stream in the hydrogen producing unit, from which the hydrogen produced i.e. make-up hydrogen, is used in the hydroprocessing stage. The invention enables minimizing natural gas consumption in the hydrogen producing unit as well as steam reformer size.

PURIFICATION OF RECYCLED AND RENEWABLE ORGANIC MATERIAL
A method is disclosed of purifying a recycled or renewable organic material, wherein the recycled or renewable organic material includes more than 1 ppm silicon as silicon compounds and/or more than 10 ppm phosphorous as phosphorous compounds. The method can include providing a feed of the lipid material; heat treating the organic material in presence of an adsorbent and the filtering organic material and hydrotreating the lipid material in a presence of a hydrotreating catalyst to obtain purified hydrotreated organic material having less than 20% organic material and/or less than 30% of the original phosphorous content of the organic material.
SIMULTANEOUS PROCESSING OF CATALYTIC AND THERMALLY CRACKED MIDDLE DISTILLATE FOR PETROCHEMICAL FEEDSTOCK
The present invention discloses an integrated process scheme for producing (i) high-octane gasoline blending stream (ii) high aromatic heavy naphtha stream which is a suitable feedstock for benzene, toluene, and xylene (BTX) production and (iii) high cetane ultra-low sulphur diesel (ULSD) stream suitable for blending in refinery diesel pool.
Method to prepare an aviation fuel component
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.
PROCESSES AND SYSTEMS FOR PRODUCING FUELS AND PETROCHEMICAL FEEDSTOCKS FROM A MIXED PLASTICS STREAM
Methods and systems for producing pyrolysis products from a mixed plastics stream are described herein. The method may include conducting pyrolysis of a plastic feedstock to produce a stream of plastic pyrolysis oil; feeding a catalytic cracking feed stream and a catalyst from a catalyst regenerator into a fluidized bed reactor, where the catalytic cracking feed stream comprises the plastic pyrolysis oil; cracking the catalytic cracking feed stream in the fluidized bed reactor to produce a product stream and a spent catalyst; and transporting the spent catalyst to the catalyst regenerator and regenerating the catalyst in the catalyst regenerator. The product stream comprises olefins having a carbon number of C.sub.2-C.sub.4 and distillate fuel.
BIOMASS PROCESSING DEVICES, SYSTEMS, AND METHODS
Biomass processing devices, systems and methods used to convert biomass to, for example, liquid hydrocarbons, renewable chemicals, and/or composites are described. The biomass processing system can include a pyrolysis device, a hydroprocessor and a gasifier. Biomass, such as wood chips, is fed into the pyrolysis device to produce char and pyrolysis vapors. Pyrolysis vapors are processed in the hydroprocessor, such as a deoxygenation device, to produce hydrocarbons, light gas, and water. Water and char produced by the system can be used in the gasifier to produce carbon monoxide and hydrogen, which may be recycled back to the pyrolysis device and/or hydroprocessor.
