  • Patent number: 11926549
    Abstract: The present disclosure discloses a treatment process and treatment system of enhanced up-flow multiphase wastewater oxidation. The treatment process includes the following steps: 1) the wastewater is fed into the up-flow multiphase wastewater oxidation system for oxidation treatment; 2) the wastewater is fed to the solid-liquid separation system for solid-liquid separation, the separated heterogeneous catalytic carrier (5) is fed back to the up-flow multiphase wastewater oxidation system, and the wastewater is fed to the neutralization and degassing system; 3) the wastewater is fed to the neutralization and degassing system to adjust a pH of the wastewater to 5.5-7.5, and then is degassed by stirring; 4) the wastewater is fed to the flocculation and sedimentation system for sludge-water separation, a supernatant is discharged, and an outward harmless treatment is performed after a pressure filtration of a sedimentary iron sludge.

  • Publication number: 20240025085
    Abstract: The present disclosure describes a sequential continuous catalytic solvolysis process and system for deconstructing co-mingled plastics containing polyesters, polyamides, and polyolefins into polyester monomers, polyamide monomers, and low molecular weight hydrocarbons, respectively. The catalysts and solvents used in the process can be recycled, and the monomers can undergo polymerization to fresh polyesters and polyamides for everyday use. The low molecular weight hydrocarbons can be used as liquefied gas.

  • Patent number: 10252251
    Abstract: The present disclosure provides a method for producing organic compounds, such as esters, from an organic feedstock that includes at least one of a biopolymer or a lipid. The method includes heating the feedstock in the presence of a solid catalyst, such as a solid, inorganic Lewis acid catalyst, and reaction medium that includes an alcohol. At least certain ester products have an ester group corresponding to a substituent of the alcohol.

  • Patent number: 10113122
    Abstract: The present disclosure provides a process that employs glycerol and a catalyst for partial transformation of heavy petroleum oils to lighter hydrocarbon liquids under mild conditions without the need of external hydrogen gas. The process uses industrially produced glycerol to upgrade heavy crudes; hydrogenates aromatics to paraffin and/or olefins without the use of external hydrogen gas; operates at mild operating conditions; and employs inexpensive catalysts. This process is completely different from the hydroconversion process where high pressurized hydrogen gas is essential. The present process requires no pressurized hydrogen gas and can significantly reduce both operating and capital costs of the traditional hydrotreating process.
