Publication number: 20230416118Abstract: An adsorbent and a method of preparing the adsorbent are described. The adsorbent includes a 2-anthracene ammonium magnetic ionic liquid (MIL), and a [FeCl4]? or a [CoCl3]? ion. The adsorbents, 2-anthracene ammonium tetrachloroferrate (III) ([2AA] FeCl4) and 2-anthracene ammonium trichlorocobaltate (II) ([2AA] CoCl3), are prepared by protonation of 2-aminoanthracene, followed by complexation with FeCl3/CoCl2. The adsorbent of the present disclosure is effective in removing contaminants such as heavy metal ions from an aqueous system in a cost-efficient and selective manner.Type: ApplicationFiled: June 23, 2022Publication date: December 28, 2023Applicant: KING FAHD UNIVERSITY OF PETROLEUM AND MINERALSInventors: Khalid ALHOOSHANI, Ahmed Abdi HASSAN, Abdulkadir TANIMU

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
