  • Patent number: 11597882
    Abstract: Systems and methods are provided for co-processing of biomass oil with mineral coker feeds in a coking environment. The coking can correspond to any convenient type of coking, such as delayed coking or fluidized coking. The biomass oil can correspond to biomass oil with a molar ratio of oxygen to carbon of 0.24 or less on a dry basis. Such types of biomass oil can be formed from pyrolysis methods such as hydrothermal pyrolysis, and are in contrast to biomass oils formed from pyrolysis methods such as fast pyrolysis. By using a biomass oil with a molar ratio of oxygen to carbon of 0.24 or less, improved yields of light coker gas oil can be achieved in conjunction with a reduction in the yield of heavy coker gas oil.

  • Publication number: 20200095510
    Abstract: The present disclosure relates to processes for producing biofuel compositions by processing hydrocarbon co-feed and a bio-oil obtained via hydrothermal liquifaction (HTL) of a cellulosic biomass to form an HTL oil. The cellulosic mass can be processed at an operating temperature of about 425° C. or less and an operating pressure of about 200 atm or less. The HTL oil is co-processed with a hydrocarbon co-feed (e.g., petroleum fraction) in a cracking unit, such as an FCC unit, a coker unit or a visbreaking unit, in the presence of a catalyst to produce a cracked product (biofuel). The bio content of the cracked product provides RIN credits for the cracked product.
