Patent number: 11414350Abstract: Oil ash comprising carbon in an amount in the range of 60% to 89% is an effective set retarder in a cement composition. The oil ash prolonged the initial and final setting time of cement paste and retained the slump flow in concrete for a longer time than concrete without the retarder. Also, the addition of oil ash to cement marginally improved the compressive strength of concrete. The advantage of oil ash is that it can be used as a solid retarder of cement hydration to substitute for the conventional commercial retarding admixtures with a limited shelf-life.Type: GrantFiled: January 25, 2019Date of Patent: August 16, 2022Assignee: King Fahd University of Petroleum and MineralsInventors: Osama Ghanem Rashed Massarweh, Mohammed Maslehuddin, Salah Uthman Al-Dulaijan, Mohammed Shameem

Patent number: 11305995Abstract: A method of producing submicron carbon particles from oil ash. The method comprises pyrolyzing the oil ash to produce a pyrolyzed oil ash and milling the pyrolyzed oil ash to produce carbon particles having a mean particle size in the submicron regime. The method produces submicron carbon particles which have a very high carbon content (90 to 99 atom %) and a very low content of oxygen, the particles having a ratio of carbon to oxygen ratio of 10:1 to 99:1. The size of the particles may be controlled by the duration of the milling. The submicron carbon particles are devoid of functionalities containing carbon-oxygen double bonds as measured by Raman spectroscopy and X-ray photoelectron spectroscopy (XPS).Type: GrantFiled: March 9, 2020Date of Patent: April 19, 2022Assignee: KING FAHD UNIVERSITY OF PETROLEUM AND MINERALSInventors: Md.
