Abstract: Systems and methods of processing pyoil are disclosed. A pyoil is treated by an adsorbent to trap, and/or adsorb gum and/or gum precursors and other heteroatom containing components, thereby removing the gum and/or gum precursors from the pyoil and producing a purified pyoil. The purified pyoil can then be cracked to produce chemicals including olefins and aromatics.

Abstract: The present invention discloses a rapid evaluation method for quality of lignin-pyrolyzed bio-oil and an application thereof, and particularly relates to a rapid evaluation method for quality of lignin-pyrolyzed bio-oil based on radical detection and an application thereof. The method can be used to evaluate the quality of lignin-pyrolyzed bio-oil by detecting the spin concentration of radicals in lignin char obtained by lignin pyrolysis, thus avoiding the complex processes involved in the evaluation for the quality of conventional pyrolyzed bio-oils such as, extraction, separation and detection and reducing the detection costs substantially. The detection method of the present invention is simple and easy to operate, thus achieving the rapid evaluation for the quality of lignin-pyrolyzed bio-oil. Moreover, the detection method of the present invention is non-contact detection without destructive samples, which is applicable to the rapid detection on the quality of lignin-pyrolyzed bio-oil in the field of industry and scientific research. The present invention further broadens the application fields of radical detection and contributes to the development of radical detection technology in the field of pyrolysis, and provides a reliable method for the detection of lignin-pyrolyzed bio-oil, which has good application prospect.

Abstract: A process is disclosed for removing fluoridated compounds from any organic medium, for example from alkylation (“alkylated”) gasoline, which can be applied at the exit of the alkylation process or inside the distillation column of the alkylation process. The process uses extractant chemical agents based on ionic liquids, of general formula C+A−, where C+ represents an organic or inorganic cation, specifically imidazolium, pyridinium, or ammonium salts, while the anion A− represents the halide-type derivatives, iron (III) salts, aluminum (III) salts, acetate, benzoate-acetates, benzoates, hexafluorophosphate, tetra-chloroborate, triflates, bis-triflates and trifluoroacetates. These ionic liquids act as extractant agents to remove fluoridated compounds from the hydrocarbon streams that are produced in the process of alkylation of isubutane with butenes, through a liquid-liquid extraction process, with a reduction of more than 80% in the content of contaminants like organofluoridated hydrocarbons.

Abstract: Systems and methods involving hydrocatalytic reactions that thermal energy obtained from combustion of coke generated by coking of at least a portion of the hydrocatalytic reaction product. Hydrocatalytic reactions can require substantial amounts of thermal energy. The present disclosure provides systems and methods that can allow for reducing the carbon footprint of the fuels formed from the hydrocatalytic reaction because at least a portion of the thermal energy used in the hydrocatalytic reaction has low carbon footprint. A fuel with low carbon footprint can qualify for certain governmental status that provides certain benefits.

Abstract: Nowadays, one of the major problems of the oil industry is the presence of large amounts of water and salts, which cannot be efficiently removed by conventional dehydrating polymers. In addition, the acid stimulation operations of petroleum wells cause the chemical degradation of demulsifiers such as polyethers and phenolic resins, reducing drastically their efficiency as water and salt removers. Based on aforementioned, a series of new copolymers has been developed; these copolymers are combinations of an acrylic and an aminoacrylic monomer and they are synthesized by semi-continuous emulsion polymerization (under starved feed conditions), which ensures both the homogeneity of the different chains as well as the randomness of the monomers distribution. The solutions of one of these random copolymers have shown an efficiency similar or superior to combinations of two or three block copolymers (formulations), when they are applied in light or heavy crude oils. The acrylic-aminoacrylic copolymers show good performance as water/oil emulsion breaker initiators, coalescence agents of water droplets and clarifiers of the remaining aqueous phase. In addition, the chemical structure of the acrylic copolymers confers resistance to degradation induced by abrupt pH changes when acid stimulation operations of wells are performed.

Abstract: Steam pyrolysis and hydroprocessing are integrated including hydrogen redistribution to permit direct processing of crude oil feedstocks to produce petrochemicals including olefins and aromatics. A feed is initially split into a light portion and a heavy portion, and the heavy portion is hydroprocessed. A hydroprocessed effluent is charged, along with steam, to a convection section of a steam pyrolysis zone. The mixture is heated and passed to a vapor-liquid separation section. A residual portion is removed and light components are charged to a pyrolysis section of the steam pyrolysis zone. A mixed product stream is recovered from the steam pyrolysis zone and it is separated into product including olefins and aromatics.
