  • Patent number: 11767477
    Abstract: Systems and methods are provided for partial upgrading of heavy hydrocarbon feeds to meet transport specifications, such as pipeline transport specifications. The systems and methods can allow for one or more types of improvement in heavy hydrocarbon processing prior to transport. In some aspects, the systems and methods can produce a partially upgraded heavy hydrocarbon product that satisfies one or more transport specifications while incorporating an increased amount of vacuum gas oil and a reduced amount of pitch into the partially upgraded heavy hydrocarbon product. In other aspects, the systems and methods can allow for increased incorporation of hydrocarbons into the fraction upgraded for transport, thereby reducing or minimizing the amount of hydrocarbons requiring an alternative method of disposal or transport.

  • Publication number: 20230109160
    Abstract: Systems and methods are provided for integrated pyrolysis and gasification of a biomass feed, either as a separate feed or under co-processing conditions. The integrated pyrolysis and gasification can be performed using any convenient reactor configuration, such as fluidized coking reactor configuration or a fluid catalytic cracking reactor configuration. The biomass feed can initially by pyrolyzed to form liquid products, gas phase products, and char. The char can then be used as the input feed to gasification. In aspects where the biomass feed is co-processed, the biomass can be co-processed with a co-feed that is suitable for processing under fluidized coking conditions or other pyrolysis conditions, such as a conventional fluidized coking feedstock.

  • Patent number: 11591531
    Abstract: Provided is a process capable of converting the cokes on spent catalysts in a fluid catalytic cracking (FCC) process into synthesis gas. The produced synthesis gas contains high concentrations of CO and H2 and may be utilized in many downstream applications such as syngas fermentation for alcohol production, hydrogen production and synthesis of chemical intermediates. A reducer/regenerator reactor for a fluid catalytic process comprising a chemical looping system to produce synthesis gas is also described.
