  • Patent number: 12012376
    Abstract: Systems and methods of producing olefins via catalytic cracking are disclosed. Hydrocarbons of a naphtha stream are isomerized by converting straight chain Cn hydrocarbons to branched Cn hydrocarbons, thereby forming an isomerized naphtha stream. The isomerized naphtha stream is subsequently fed to a catalytic cracking unit such that the hydrocarbons of the isomerized naphtha stream form olefins. In the catalytic cracking process, the reaction temperature can be kept lower than 680° C., thereby increasing the reactivity and minimizing catalyst deactivation in the catalytic cracking process.

  • Publication number: 20240182796
    Abstract: A process for converting a feedstock including dicyclopentadiene to monoaromatic hydrocarbons, the process including providing a hydrocracking catalyst including a zeolite support having an average pore diameter of 5 to 13 nanometers, such as 9 to 12 nanometers, and greater than 3 to 15 weight percent, such as 5 to 15 weight percent of molybdenum tungsten, nickel, cobalt, platinum, palladium, or a combination comprising at least one of the foregoing impregnated on the zeolite support based on a total weight of the hydrocracking catalyst: and contacting the feedstock with the hydrocracking catalyst in the presence of hydrogen to provide a reaction product stream including the monoaromatic hydrocarbons converted from the dicyclopentadiene.

  • Patent number: 11396630
    Abstract: A method of producing olefins by catalytic cracking of hydrocarbons is disclosed. The method may include catalytic cracking hydrocarbons in a feed stream that includes the hydrocarbons and the dry gas diluent. The catalytic cracking may be carried out in a process using a train of fixed bed reactors while one or more other trains of fixed bed reactors are being regenerated or are on standby after being regenerated. When the train of fixed bed reactors being used needs regenerating, it is taken out of service and the one or more other trains of fixed bed reactors put in service to carry out the catalytic cracking process. Dry gas instead of steam may be used to reduce the partial pressure of hydrocarbons.

  • Patent number: 11390572
    Abstract: Systems and methods for producing light olefins and BTX are disclosed. A feed stream comprising mixed C4 paraffins is first separated into a first stream comprising primarily isobutane, and a second stream comprising primarily n-butane. The first stream is processed in a catalytic cracking unit and the second stream is processed in a steam cracking unit. The resulting streams from the catalytic cracking unit and the steam cracking unit are separated to form product streams including an ethylene stream, a propylene stream, and a BTX stream.
