  • Publication number: 20230330723
    Abstract: A process for recycling contaminated solid material is provided. The process comprises heating the material yielding a solid phase, an oil phase, and a gas phase. Prior to being heated, the material is subjected to a pre-treatment involving a dehalogenation agent (DHA). The gas phase obtained is further subjected to a purification treatment. The DHA agent used is regenerated using a regeneration agent (RGA) and further re-used in the process.

  • Patent number: 11739273
    Abstract: A process for removing metals in a petroleum oil material. The process comprises causing the petroleum oil material to react with a removing agent which comprises a phosphoric acid ester. A microwave irradiation environment was created during the reaction to provide the required energy essential for separating such contaminations from the oil chemical network. The process of the invention is applied at ambient pressure and low temperature compared to the conventional metal removal processes. The process of the invention can be readily scaled up and integrated into an industrial facility.

  • Patent number: 11479731
    Abstract: The present invention relates to a process for removing sulfur (S)-containing compounds in crude oil material. The process comprises causing the crude oil material to react with a removing agent, which comprises a phosphoric acid ester, and an aqueous phase in the presence of microwaves. The process of the invention is applied at ambient pressure and relatively low temperature compared to the conventional desulfurization processes. The process of the invention can be readily scaled up and integrated into an industrial facility.
