The present disclosure relates to methods for the production of a renewable crude oil from plant oils and animal fats. The renewable crude is a drop-in renewable crude that can be processed in a petroleum refinery with minimal or no modifications.

The present invention relates to debottleneck solution for delayed Coker unit. More particularly, this invention relates to bottoms of vacuum residuum routed to Coker unit through de-asphalting unit to avoid revamp of existing Coker for the processing of heavier feed stock when there is a change in crude slate. Another object of the invention, in particular, relates to improved delayed coking products, a process used in petroleum refineries to crack petroleum residue, thus converting it into gaseous and liquid product streams and leaving behind solid, carbonaceous petroleum coke.

Method of producing pyrolysis products from mixed plastics along with an associated system for processing mixed plastics. The method includes conducting pyrolysis of a plastic feedstock to produce plastic pyrolysis oil; feeding the plastic pyrolysis oil to a first fractionator to separate the plastic pyrolysis oil into a distillate fraction including naphtha and diesel and a vacuum gas oil fraction; and feeding the distillate fraction to a three step hydrotreating operation. The three step hydrotreating operation includes feeding the distillate fraction to a first hydrotreating unit to remove di-olefins to produce a first product stream, feeding the first product stream to a second hydrotreating unit to remove mono-olefins to produce a second product stream; and feeding the second product stream to a third hydrotreating unit to remove sulfur and nitrogen by hydrodesulfurization and hydrodenitrogenation to produce a third product stream. Such system may be integrated with a conventional refinery.

This disclosure relates to the production of chemicals and plastics using pyrolysis oil from the pyrolysis of plastic waste as a co-feedstock along with a petroleum-based, fossil fuel-based, or bio-based feedstock. In an aspect, the polymers and chemicals produced according to this disclosure can be certified under International Sustainability and Carbon Certification (ISCC) provisions as circular polymers and chemicals at any point along complex chemical reaction pathways. The use of a mass balance approach which attributes the pounds of pyrolyzed plastic products derived from pyrolysis oil to any output stream of a given unit has been developed, which permits ISCC certification agency approval.

A modular crude oil refinery (MCOR) is designed for smaller scale deployment with a capacity to process in the range of 3,000-4,000 barrels of crude oil per day in a single production unit and with the potential to scale to over 100,000 barrels per day with linked production units. More specifically, a MCOR includes a low temperature, low pressure primary separation reactor, condensing system and recirculation systems operating in a closed loop configuration that enable the production of both heavy and light hydrocarbon products with substantially no emissions. The MCOR has the capability to receive and process crude-oil feedstocks of varying API gravity and be controlled to produce a variety of both heavy and light products including cleaner-burning bunker fuels, jet fuels, diesel fuels, gasoline fuels and asphalt binders.

Methods are provided for using a molecular sieve catalyst for dewaxing formed using a synthesis mixture comprising a morphology modifier. The catalyst may be used, for example, for production of a lubricant base stock. For example, ZSM-48 crystals formed using the morphology modifier (and/or formulated catalysts made using such crystals) can have an increased activity and/or can provide an improved yield during catalytic dewaxing of lubricant base stocks.

The present invention provides methods and an apparatuses for converting polymeric material into hydrocarbon products.

Systems and methods are provided for co-processing of plastic waste in a coking environment or other thermal conversion environment. The co-processing of plastic waste in a coking environment can be performed by performing four types of processes on the plastic waste. The plastic waste can be conditioned by classifying and sizing of the plastic waste to improve the suitability of the plastic waste for co-processing. The conditioned plastic waste particles can be entrained and/or dissolved into a solvent and/or the base feed. The solution and/or slurry of plastic waste can be passed into a coking environment, such as a fluidized coking environment or a delayed coking environment. The plastic waste can then be co-processed in the coking environment to generate liquid product.

The present invention describes the coprocessing of a lignocellulosic liquid stream and an intermediate fossil stream in the oil refining process comprising the steps of (a) contacting said intermediate fossil stream and said lignocellulosic liquid stream with a stream of solvent of C.sub.3-C.sub.10 hydrocarbons in an extraction section, obtaining a stream of extract with solvent and a stream of raffinate with solvent; and (b) sending said stream of extract with solvent to a separation section, obtaining a deasphalted oil stream comprising solvent-free carbon of renewable origin and a stream of recovered solvent. The present invention further relates to a process for producing fuels from the deasphalted oil stream comprising carbon of renewable origin, wherein the process comprises sending the deasphalted oil stream to a conversion section of an oil refinery. The conversion section is selected from catalytic hydrocracking unit, thermal cracking, fluidized-bed catalytic cracking, visbreaking, delayed coking and catalytic reforming.

A renewable hydrocarbon composition as disclosed includes monobranched isoparaffins, dibranched isoparaffins, tribranched isoparaffins multibranched isoparaffins, and n-paraffins, having carbon numbers from C8 to C30. Said renewable hydrocarbon composition has high cetane number and excellent cold properties. The renewable hydrocarbon composition can be used as diesel fuel or as a diesel fuel component.
