  • Patent number: 12270009
    Abstract: A process for converting plastic feedstock into a lubricant on an industrial scale can include a reactor having a filter integrated therein to allow for separation and recovery of catalyst so it can be washed and reused in subsequent conversion processes. Such recycling of the catalyst can allow for an industrial scale conversion process.

  • Publication number: 20230405557
    Abstract: A method of upcycling polymers to useful hydrocarbon materials. A catalyst with nanoparticles on a substrate selectively docks and cleaves hydrocarbon chains forming shorter hydrocarbon chains. The catalyst includes metal nanoparticles, such as monometallic nickel or ruthenium nanoparticles or a plurality of nanoparticles of two or more metals, on a metal oxide substrate.

  • Publication number: 20230096521
    Abstract: A method for conversion of food waste to biofuel can include a first fermentation in which food waste is converted C2-C4 short-chain carboxylic acids, and a second fermentation in which the C2-C4 short-chain carboxylic acid are elongated into C5-C8 medium-chain carboxylic acids. Medium-chain carboxylic acids can undergo hydrogenation-dehydration of the medium-chain carboxylic acids into C5-C8 linear olefins. The C5-C8 linear olefins are then oligomerized to a C10-C25 mixture comprising olefins, paraffin, cycloparaffins, and aromatics through dimerization; and saturated to C10-C25 mixture by hydrogenation to produce the biofuel.

  • Patent number: 8440867
    Abstract: The invention provides a method for producing ethanol, the method comprising establishing an atmosphere containing methanol forming catalyst and ethanol forming catalyst; injecting syngas into the atmosphere at a temperature and for a time sufficient to produce methanol; and contacting the produced methanol with additional syngas at a temperature and for a time sufficient to produce ethanol. The invention also provides an integrated system for producing methanol and ethanol from syngas, the system comprising an atmosphere isolated from the ambient environment; a first catalyst to produce methanol from syngas wherein the first catalyst resides in the atmosphere; a second catalyst to product ethanol from methanol and syngas, wherein the second catalyst resides in the atmosphere; a conduit for introducing syngas to the atmosphere; and a device for removing ethanol from the atmosphere. The exothermicity of the method and system obviates the need for input of additional heat from outside the atmosphere.

  • Patent number: 5306683
    Abstract: A zeolite based catalyst for activation and conversion of methane. A zeolite support includes a transition metal (Mo, Cr or W) sulfide disposed within the micropores of the zeolite. The catalyst allows activation and conversion of methane to C.sub.2 + hydrocarbons in a reducing atmosphere, thereby avoiding formation of oxides of carbon.
