  • Patent number: 10703983
    Abstract: A method of processing of shredded rubber-containing waste involves its preliminary preparation, thermal decomposition in a furnace, separation of decomposition products into vapor-gas mixture and solid residue, and separation of a heavy hydrocarbon fraction from the vapor-gas mixture. Preliminary preparation of the waste is carried out by its blowing with water vapor until a waste temperature reaches 100° C., and thermal decomposition is carried out in residual oil in the starting phase, and afterwards in the atomized generated heavy hydrocarbon fraction and superheated water vapor, their weight ratio being (0.1-0.5):1. The heavy hydrocarbon fraction is separated from the vapor-gas mixture with water by atomizing it into the vapor-gas mixture flow at the rate of 5-15% of the mass flow rate of the mixture, while metal is extracted from the solid residue by magnetic separation, after which a product containing zinc oxide is separated by dielectric separation.

  • Patent number: 10549455
    Abstract: The disclosed invention describes a novel approach to the utilization of the fine mineral matter derived from coal and/or coal refuse (a by-product of coal refining) to convert a non-biodegradable plastic into a biodegradable plastic. The fine mineral matter could also be based on volcanic basalt, glacial rock dust deposits, iron potassium silicate and other sea shore mined deposits. The conversion of the non-biodegradable plastic into biodegradable plastic in soil further increases nutrients availability in soil with the transition metals released as a result of biodegradation of the biodegradable plastic.

    Abstract: A new family of coherently grown composites of TUN and IMF zeotypes has been synthesized and shown to be effective catalysts for catalytic pyrolysis of biomass. These zeolites are represented by the empirical formula. NanMmn+RrQqAl1-xExSiyOz where M represents zinc or a metal or metals from Group 1, Group 2, Group 3 or the lanthanide series of the periodic table, R is an A,?-dihalosubstituted paraffin such as 1,4-dibromobutane, Q is a neutral amine containing 5 or fewer carbon atoms such as 1-methylpyrrolidine and E is a framework element such as gallium. The process involves contacting a carbonaceous biomass feedstock with UZM-39 at pyrolysis conditions to produce pyrolysis gases comprising hydrocarbons. The catalyst catalyzes a deoxygenation reaction converting oxygenated hydrocarbons into hydrocarbons and removing the oxygen as carbon oxides and water. A portion of the pyrolysis gases is condensed to produce low oxygen biomass-derived pyrolysis oil.
