Patent number: 11613712Abstract: For the shipping industry, these fuels provide solutions to long outstanding technical problems that heretofore hindered supply of low sulfur marine fuels in quantities needed to meet worldwide sulfur reduction goals. When ships on the open seas burn cheap low grade heavy bunker oils high in sulfur, nitrogen and metals, the SOx, NOx, and metal oxides go to the environment. This invention converts essentially all of each barrel of crude feed to a single ultraclean fuel versus conventional refining where crude feed is cut into many pieces, and each piece is sent down a separate market path meeting various different product specifications. When in port, ships can generate and sell electricity to land based electrical grids to offset fuel cost in an environment-friendly manner.Type: GrantFiled: May 31, 2022Date of Patent: March 28, 2023Assignee: Mawetal LLCInventors: Mohammed Wohaibi, Tom F.

Patent number: 11603503Abstract: This invention is related to an additive composition comprising metal-based quantum clusters (QCs) dispersed in a hydrocarbon medium. The additive composition is useful as a fuel additive, as it acts as a combustion improver for liquid and gaseous fuels. The invention describes a process for the synthesis of the additive composition comprising metal-based materials in atomic cluster form in hydrocarbon dispersible medium. The stable liquid dispersion of the QC has been doped into the hydrocarbon fuels at required concentrations. The measurable flame temperature of the fuels, e.g., commercial LPG on burner has been observed to increase by at least 60-80° C. The flame with high heat through put can be used for efficient cooking, heating, annealing and other high thermal applications. The additive composition may also be used to improve the fuel economy of the liquid hydrocarbon fuels.Type: GrantFiled: May 19, 2022Date of Patent: March 14, 2023Assignee: INDIAN OIL CORPORATION LIMITEDInventors: Koushik Bhowmik, Mukesh Kumar Vyas, Jyoti Ota, Samik Kumar Hait, Vivekanand Kagdiyal, Deepak Saxena, Sankara Sri Venkata Ramakumar
