  • Patent number: 10751710
    Abstract: A method of making a multifunctional catalyst for upgrading pyrolysis oil includes contacting a zeolite support with a solution including at least a first metal catalyst precursor and a second metal catalyst precursor, the first metal catalyst precursor, the second metal catalyst precursor, or both, including a heteropolyacid. Contacting the zeolite support with the solution deposits or adsorbs the first metal catalyst precursor and the second catalyst precursor onto outer surfaces and pore surfaces of the zeolite support to produce a multifunctional catalyst precursor. The method further includes removing excess solution from the multifunctional catalyst precursor and calcining the multifunctional catalyst precursor to produce the multifunctional catalyst comprising at least a first metal catalyst and a second metal catalyst deposited on the outer surfaces and pore surfaces of the zeolite support.

  • Patent number: 10647925
    Abstract: Fuels and/or fuel blending components can be formed from hydroprocessing of high lift deasphalted oil. The high lift deasphalting can correspond to solvent deasphalting to produce a yield of deasphalted oil of at least 50 wt %, or at least 65 wt %, or at least 75 wt %. The resulting fuels and/or fuel blending components formed by hydroprocessing of the deasphalted oil can have unexpectedly high naphthene content and/or density. Additionally or alternately, deasphalted oil generated from high lift deasphalting represents a disadvantaged feed that can be converted into a fuel and/or fuel blending components with unexpected compositions. Additionally or alternately, the resulting fuels and/or fuel blending components can have unexpectedly beneficial cold flow properties, such as cloud point, pour point, and/or freeze point.
