Abstract: Systems and methods for upgrading a hydrocarbon stream to a lower boiling point hydrocarbon feed material are disclosed. The system includes a feeding device to transport a hydrocarbon stream that includes an alternative feedstock. The hydrocarbon stream is partially cracked in a first cracking unit producing a lower boiling point hydrocarbon feed material, a catalyst rich heavy hydrocarbon stream, and coke. A slurry settler receives the catalyst rich heavy hydrocarbon stream and coke and separates the catalyst from the catalyst rich heavy hydrocarbon stream thereby defining a catalyst rich stream and a heavy hydrocarbon stream. A coking vessel receives the heavy hydrocarbon stream and coke and separates the heavy hydrocarbons from the coke thereby defining a heavy hydrocarbon stream. Finally, a second cracking unit that receives the lower boiling point feed material from the first cracking unit and produces olefins and aromatics.

Abstract: Disclosed is a process in which the jump in hydrogenation capacity, necessary to hydroconvert heavy oils totally to light hydrocarbons (350° C.−), is obtained by using an upflow reactor equipped with a gas distributor having a high density of orifices, which is capable of causing the packing of the gas bubbles, this being the most advantageous fluid dynamic condition. The resulting conversion products are suitable as petrochemical feedstocks.

Abstract: Embodiments of the disclosure include processes for hydroconversion of hydrocarbon feedstocks in ebullated bed reactor systems. In particular, the systems comprise two or more ebullated bed reactors comprising catalyst particles, one or more inter-stage separation vessels, which are in fluid communication, and allow for the introduction of an additional solvent into the system between the final inter-stage separation vessel and the final ebullated bed reactor in the flow path. The processes include the addition of a solvent comprising water to an inter-stage liquid product prior to contact with the final ebullated bed reactor, which improves catalytic performance.

Abstract: A catalytic membrane composite that includes porous supported catalyst particles durably enmeshed in a porous fibrillated polymer membrane is provided. The porous fibrillated polymer membrane may be manipulated to take the form of a tube, disc, or diced tape and used in multiphase reaction systems. The supported catalyst particles are composed of at least one finely divided metal catalyst dispersed on a porous support substrate. High catalytic activity is gained by the effective fine dispersion of the finely divided metal catalyst such that the metal catalyst covers the support substrate and/or is interspersed in the pores of the support substrate. In some embodiments, the catalytic membrane composite may be introduced to a stirred tank autoclave reactor system, a continuous flow reactor system, or a Parr Shaker reaction system and used to effect the catalytic reaction.

Abstract: A raw material composition for producing oxygen carriers includes a first component which is one or more of nickel oxide and nickel hydroxide and a second component which is one or more of boehmite, cerium oxide, cerium hydroxide, magnesium oxide, magnesium hydroxide, and titanium oxide, wherein, when the first component is nickel oxide, the second component includes cerium hydroxide. Such a raw material composition for producing oxygen carriers of the present invention is formed into oxygen carriers according to an oxygen carrier producing method, which will be described below, by adjusting the composition, formulation of raw materials, and degree of homogenization. Then, it is possible to produce oxygen carriers having physical properties such as a shape, a particle size, and a particle distribution suitable for a fluidized bed process or a high speed fluidized bed process and having improved wear-resistance, long-term durability, and oxygen transfer performance.

Abstract: A pyrolysis process comprises introducing one or more chemical reactants into a reactor containing a liquid maintained at a high temperature, producing chemical products in the liquid based on the high temperature, allowing the solid product to grow in particle size, accumulating the solid product in the liquid, and removing the solid product from the reactor while retaining a substantial portion of the liquid within the reactor. The chemical products comprise a solid chemical product that is mixed with the liquid.
