Patent number: 11629235Abstract: Urea and amine comprising sol-gel hybrid coatings have been developed for numerous applications, including capillary microextraction-high performance liquid chromatographic analysis from aqueous samples. A fused silica capillary may be coated from the inside with surface bonded coating material and may be created by in-situ sol-gel reaction(s). Urea-functionalized coatings can be immobilized on the inner surface of a capillary by condensing silanol groups of capillary and sol-solution. Urea functionalized, sol-gel coated capillaries may be installed, e.g., in HPLC manual injection ports, and optionally pre-concentrated analytes including phenols, ketones, aldehydes, and/or polyaromatic hydrocarbons, from highly polar to non-polar, maybe analyzed by online extraction and high-performance liquid chromatographic. Such coatings may achieve sensitivities with lower detection limits (S/N=3) of 0.10 ng/mL to 14.29 ng/mL, with reproducibilities of <12.0% RSD (n=3), or <10.Type: GrantFiled: January 4, 2019Date of Patent: April 18, 2023Assignee: King Fahd University of Petroleum and MineralsInventors: Khalid R.

Patent number: 11613709Abstract: A method of preparing hydrodesulfurization catalysts having cobalt and molybdenum sulfide deposited on a support material containing mesoporous silica. The method utilizes a sulfur-containing silane that dually functions as a silica source and a sulfur precursor. The method involves an one-pot strategy for hydrothermal treatment and a single-step calcination and sulfidation procedure. The application of the hydrodesulfurization catalysts in treating a hydrocarbon feedstock containing sulfur compounds to produce a desulfurized hydrocarbon stream is also specified.Type: GrantFiled: August 16, 2021Date of Patent: March 28, 2023Assignee: KING FAHD UNIVERSITY OF PETROLEUM AND MINERALSInventors: Khalid R. Alhooshani, Saheed Adewale Ganiyu, Abdulkadir Tanimu
