  • Patent number: 11053447
    Abstract: Treatment of hydrocarbon streams, and in one non-limiting embodiment refinery distillates, with reducing agents, such as borohydride and salts thereof, alone or together with at least one co-solvent results in reduction of the sulfur compounds such as disulfides, mercaptans, thiophenes, and thioethers that are present to give easily removed sulfides. In one non-limiting embodiment, the treatment converts the original sulfur compounds into hydrogen sulfide or low molecular weight mercaptans that can be extracted from the distillate with caustic solutions, hydrogen sulfide or mercaptan scavengers, solid absorbents such as clay or activated carbon or liquid absorbents such as amine-aldehyde condensates and/or aqueous aldehydes.

  • Patent number: 11046894
    Abstract: A nanocomposite composition for oxidative desulfurization of liquid hydrocarbon fuels, is disclosed. The nanocomposite composition comprises an amorphous mesoporous titania-silica (TiO2—SiO2) nanocomposite oxidative desulfurization (ODS) catalyst-adsorbent, including, a chelating agent, an alcohol, an alkoxides precursor of silica and titania, water, an organic polymer and a textural agent. The nanocomposite ODS catalyst-adsorbent is prepared with the aid of polyethylene glycol (PEG) as directing agent and citric acid (CA) as chelating agent. The PEG increases the specific surface area and average pore diameter of ODS catalyst-adsorbent, which facilitates the diffusion of bulky sulfur compounds into porosities of catalyst and adsorption of oxidized sulfur compounds on the catalyst surface. The citric acid controls the hydrolysis and condensation of titanium precursor, which improves ODS performance of catalyst-adsorbent.

  • Patent number: 11041128
    Abstract: A catalyst system has been designed that disrupts the sedimentation process. The catalyst system achieves this by saturating key feed components before the feed components are stripped into their incompatible aromatic cores. The efficacy of this disruptive catalyst system is particularly evident in a hydrocracker configuration that runs in two-stage-recycle operation. The catalyst is a self-supported multi-metallic catalyst prepared from a precursor in the hydroxide form, and the catalyst must be toward the top level of the second stage of the two-stage system.

  • Patent number: 11021664
    Abstract: The invention relates to a catalytic hydrocracker with two different catalyst beds within the reactor where each is loaded with a catalyst that has different hydrocracking properties. A first catalyst bed preferably cracks heavy oil more aggressively than the catalyst in the second bed. The catalytic hydrocracker includes further two recycle lines such that one directs unconverted oil through both hydrocracker beds and a bypass inlet is positioned between the first and second catalyst beds to admit unconverted oil to pass only through the second less aggressive hydrocracker catalyst bed. When gasoline prices favor the production of gasoline, less unconverted oil is recycled through the bypass therefore making more gasoline, but when prices favor the production of j et and diesel, more recycle is directed through the bypass recycle thus making less gasoline and more diesel and jet fuel.
