The present invention relates to automated waste recovering system and method which is not limited to a specific type of waste only. The system comprises a reactor for pyrolysis, a condensing unit connected to a water-cooled chiller to obtain liquid phase products and non-condensable gas, a gas treatment unit, a series of gas filtration unit to obtain clean gas, a storage and a control unit. The system also comprises a gas mixer unit to mix the non-condensable gas with hydrogen to obtain hydrocarbon rich gas, an artificial fuel condensing unit for condensing the hydrocarbon rich gas to obtain artificial fuel and water, which subsequently separated in a phase separator unit. The present invention provides a means to achieve constant yield by controlling conditions in the reactor and further increase the yield by producing artificial fuel.

Methods and systems are provided for the conversion of waste plastics into various useful downstream recycle-content products. More particularly, the present system and method involves integrating a pyrolysis facility with a cracker facility by introducing at least a stream of r-pyrolysis gas into the cracker facility. In the cracker facility, the r-pyrolysis gas may be separated to form one or more recycle content products, and can enhance the operation of the facility.

Systems and methods are provided for separation of particles and/or asphaltenes from heavy hydrocarbon fractions. The heavy hydrocarbon fraction can correspond to a feed including particles or a processing effluent that includes particles. If the heavy hydrocarbon fraction is mixed with lower boiling fractions, a separation can be performed to reduce or minimize the amount of hydrocarbons that are present in the heavy hydrocarbon fraction. The heavy hydrocarbon fraction can then be mixed with a sufficient amount of a separation solvent to cause a phase separation. One phase can correspond to the separation solvent plus a portion of the hydrocarbons. The other phase can correspond to hydrocarbons rejected by the separation solvent plus the particles from the heavy hydrocarbon fraction. The phases can then be separated from each other using a solids-liquid centrifugal separator.

The present embodiment pertains to a technique for removing at least 90% of the chlorine in high Cl content oil by performing a high-temperature treatment using solid acid substances. The oil removed Cl from a waste oil can be incorporated in a refinery process and thereby converted into fuel or a chemical product. Chlorine can be removed through a high-temperature heat treatment after mixing high Cl content oil with a solid acid material. In the process of removing Cl, major impurities, such as S, N, and O, as well as Na, Ca, and Fe, which can act as catalyst poisons in the catalytic reactions of a refinery process, are also removed at the same time.

A method of producing advanced carbon materials can include providing coal to a processing facility, beneficiating the coal to remove impurities from the coal, processing the beneficiated coal to produce a pitch, and treating the pitch to produce an advanced carbon material such as carbon fibers, carbon nanotubes, graphene, resins, polymers, biomaterials, or other carbon materials.

Provided is a continuous process for converting waste plastic into recycle for polyethylene polymerization. In one embodiment, the process comprises selecting waste plastics containing polyethylene and/or polypropylene and passing the waste plastics through a pyrolysis reactor to thermally crack at least a portion of the polyolefin waste and produce a pyrolyzed effluent. The pyrolyzed effluent is separated into offgas, a naphtha/diesel fraction, a heavy fraction, and char. The naphtha/diesel fraction is passed to a crude unit distillation column in a refinery where a straight run naphtha (C.sub.5-C.sub.8) fraction or a propane/butane (C.sub.3-C.sub.4) fraction is recovered. The straight run naphtha fraction (C.sub.5-C.sub.8) or the propane/butane (C.sub.3-C.sub.4) fraction is passed to a steam cracker for ethylene production. The heavy fraction from the pyrolysis unit can also be passed to an isomerization dewaxing unit to produce a base oil.

Systems and methods are provided for co-processing of biomass oil with mineral coker feeds in a coking environment. The coking can correspond to any convenient type of coking, such as delayed coking or fluidized coking. The biomass oil can correspond to biomass oil with a molar ratio of oxygen to carbon of 0.24 or less on a dry basis. Such types of biomass oil can be formed from pyrolysis methods such as hydrothermal pyrolysis, and are in contrast to biomass oils formed from pyrolysis methods such as fast pyrolysis. By using a biomass oil with a molar ratio of oxygen to carbon of 0.24 or less, improved yields of light coker gas oil can be achieved in conjunction with a reduction in the yield of heavy coker gas oil.

Described herein are pyrolysis systems and pyrolysis processes for achieving a lighter yield slate than provided in conventional pyrolysis systems. Aspects include: recycling a gaseous pyrolysis product into the pyrolysis reactor to enhance the mixing of the pyrolysis system reactants; installing a bottoms liquid recycle stream to better mix the pyrolysis system reactants; and/or recycling at least a portion of a heavy fraction of the gaseous pyrolysis reactor effluent from a condenser system into the pyrolysis reactor liquid. These improvements can enhance the economic viability of plastic wastes to liquid and gaseous hydrocarbon products which are used for making circular chemical and polymer products.

A biofuel includes a mixture having a gasoil generated from hydropyrolysis and hydroconversion of a solid biomass containing lignocellulose and an isomerized hydroprocessed ester and fatty acid (HEFA) generated from hydrotreating a renewable resource having fats and oils. The gasoil has a cetane index less than 46 and at least 10 parts per million weight (ppmw) of a heteroatom and a cetane index of the biofuel is greater than 46.
