摘要： A process for upgrading a naphtha feed includes separating the naphtha feed into at least a light naphtha fraction, contacting the light naphtha fraction with hydrogen in the presence of at least one cyclization catalyst, and contacting the cyclization effluent with at least one cracking catalyst. Contacting the light naphtha fraction with hydrogen in the presence of at least one cyclization catalyst may produce a cyclization effluent comprising a greater concentration of naphthenes compared to the light naphtha fraction. Contacting the cyclization effluent with at least one cracking catalyst under conditions sufficient crack at least a portion of the cyclization effluent may produce a fluid catalytic cracking effluent comprising light olefins, gasoline blending components, or both. A system for upgrading a naphtha feed includes a naphtha separation unit, a cyclization unit disposed downstream of the naphtha separation unit, and a fluid catalytic cracking unit disposed downstream of the cyclization unit.

摘要： Provided is a technology of converting an oil having a high content of Cl into a solvent. Impurities such as Cl, S, N, and metals are removed from an oil having a boiling point of 180 to 340° C. in a waste oil having a high content of Cl, and hydroisomerization is carried out, thereby applying an oil having a high isoparaffin ratio as a solvent. After a separation by boiling points according to the properties of the solvent product, a solid acid material and an oil having a high Cl content are mixed, impurities are removed by a heat treatment at a high temperature, and hydroisomerization is carried out by a noble metal/1-D zeolite catalyst, thereby, manufacturing a solvent product.

摘要： Processes and systems for hydrocarbon pyrolysis. In some embodiments, a hydrocarbon can be heated within a convection section of a steam cracking furnace and combined with an aqueous fluid to produce a heated mixture. A heavy feed that includes a plastic material can be introduced into a vessel and a portion of the plastic material can be cracked therein. Liquid and vapor effluents exiting the vessel can be obtained. At least a portion of the liquid effluent can be heated to produce a heated fluid stream that can be recycled to the vessel. The vapor effluent can be combined with the heated mixture to produce a combined mixture that can be heated within the convection section to produce a heated combined mixture. At least a portion of the heated combined mixture can be cracked within a radiant section of the steam cracking furnace to produce a steam cracker effluent.

摘要： A system is disclosed for desulfurizing liquid fossil fuel comprising: liquid fossil fuel supply; a first mixer; a second mixer; an oxidizer supply; a catalyst supply; an extractant supply; a centrifuge; and an ultrasoncially induced cavitation reactor comprising: a vessel configured to receiving the liquid fossil fuel, oxidizer and catalyst as a multiphase reaction medium; and a vibrating probe disposed within walls of the vessel. The multiphase reaction medium is configured to flow generally parallel to the probe. The probe is configured to produce pressure waves to induce formation of nano-sized bubbles in the multiphase reaction medium along one or more cavitation zones along a length of the probe. The vessel walls are at a distance of approximately 0.5 to 5 times the diameter of a smallest diameter of the probe. The first mixer is configured to receive and mix the liquid fossil fuel supply with the catalyst supply. The reactor is configured to receive the mix of liquid fossil fuel supply and the catalyst supply from the first mixer and the oxidizer supply. The second mixer is configured to receive the multiphase reaction medium and extractant supply to form processed fuel. The centrifuge is configured to receive the processed fuel from the second mixer to extract sulfones to yield an organic phase and aqueous phase. The organic phase substantially consists of desulfurized fuel.

摘要： Systems and methods are provided for expanding the operating envelope for an FCC reaction system while also reducing or minimizing the net environmental CO2 emissions associated with the FCC reaction system and/or the resulting FCC products. In some aspects, reducing or minimizing net environmental CO2 emissions can be achieved during processing of unconventional feeds, such as feeds that are traditionally viewed as having insufficient tendency to coke in order to maintain heat balance within an FCC reaction system. In other aspects, this can correspond to expanding the production of diesel within an FCC reaction system by modifying the reaction conditions in a manner that can cause a reaction system to fall out of heat balance (relative to the heat needed to maintain a target operating temperature) even when using conventional feeds

摘要： An isomerization catalyst is provided, along with corresponding systems and methods, which provides improved isomerization for bio-derived feeds in reaction environments where by-products from deoxygenation are present. The catalyst provides unexpectedly increased activity and/or selectivity in situations where, for example, a deoxygenation effluent is cascaded to the isomerization catalyst. Additionally, the isomerization catalyst can assist with reducing or minimizing hydrogen consumption during isomerization. The increased activity, stability, and/or reduced hydrogen consumption is achieved in part based on using a dispersion agent when adding base metals to the catalyst. In addition to the base metals, the catalyst includes a zeolitic framework structure suitable for isomerization.

摘要： Systems and methods are provided for reducing hydrogen consumption during deoxygenation of bio-derived (or at least partially bio-derived) feedstocks. The reduced hydrogen consumption is achieved by performing the deoxygenation in the presence of a bulk multimetallic catalyst and/or in the presence of a base metal dewaxing catalyst having reduced metal stack heights. Additionally, due in part to being able to reduce or minimize hydrogen consumption, the heat release during deoxygenation can also be reduced, thus allowing a smaller catalyst volume to perform deoxygenation.
