Patent number: 8252256Abstract: A simple, room-temperature method of producing zinc oxide nanoparticles was established by reacting zinc nitrate hexahydrate and cyclohexylamine (CHA) in either aqueous or EtOHic medium. Particles of polyhedra morphology were obtained for zinc oxide, prepared in EtOH (ZnOE), while an irregular spherical morphology, mixed with some chunky particles forzinc oxide prepared in water (ZnOW). The results indicate that there are significant morphological differences between ZnOE and ZnOW. ZnOE showed a regular polyhedral shape, while spherical and chunky particles were observed for ZnOW. The morphology was crucial in enhancing the cyanide ion photocatalytic degradation efficiency of ZnOE by a factor of 1.5 in comparison to the efficiency of ZnOW at equivalent loading of 0.02 ZnO nanoparticles wt %. Increasing the loading wt % of ZnOE from 0.01 to 0.07 led to an increase in the photocatalytic degradation efficiency from 67% to 90% after 45 minutes and a doubling of the first-order rate constant (k).Type: GrantFiled: January 1, 2012Date of Patent: August 28, 2012Assignee: King Abdulaziz City for Science and Technology (KACST)Inventors: Abdulaziz A Bagabas, Reda M.

Publication number: 20120138449Abstract: The present disclosure relates to a method and process to remove the remaining sulfur in four types of Arabian crude oils (Arabian Heavy) (AH) and straight-run diesel (SRD) by ionizing radiation. Radiation-induced desulfurization is not feasible for absorbed doses up to 200 kGy. Most of the organically bound sulfur and/or elemental sulfur and hydrogen sulfide still exist in the irradiated samples. Sulfur removal from crude oil and straight-run diesel was achieved by combining gamma-irradiation with other physical/chemical processes (i.e. liquid/liquid extraction and oxidation) which provided a considerable levels of total sulfur reduction in the investigated products (AH and SRD). The best removal processes for Arabian heavy crude oil and straight-run diesel resulted in reducing total sulfur content up to 36% (AH) and 78% (SRD) corresponding to (liquid process/200 kGy) and (liquid process/200 kGy) for AH and SRD, respectively.Type: ApplicationFiled: February 12, 2012Publication date: June 7, 2012Applicant: King Abdulaziz City for Science and Technology (KACST)Inventors: Ahmed Ali Basfar, Khaled Abdel-Aziz Mohamed

Patent number: 8110708Abstract: Ruthenium/activated charcoal (Ru/AC) treated with synthesized nano-ZnO (n-ZnO) is used for the first time as a novel composite catalyst in one-step self-condensation of acetone (DMK) to methyl isobutyl ketone in the gas phase. The DMK self-condensation was performed under atmospheric pressure, in a tubular glass fixed-bed microreactor, under DMK and H2 continuous flow at temperature in the range of 523 to 648 K. Addition of n-ZnO to Ru/AC resulted in a pronounced increase in the degree of dispersion of Ru and in the acidic/basic sites concentration ratio. For the one-step synthesis of MIBK at 623 K, the composite catalyst with 2.5 wt % Ru loading was an active and selective bi-functional composite catalyst with balanced acid/base and hydrogenation properties. At 523 K, isopropyl alcohol, product of DMK-direct hydrogenation, was produced in high selectivity for instantly investigated composite catalyst.Type: GrantFiled: April 27, 2011Date of Patent: February 7, 2012Assignee: King Abdulaziz City for Science and Technology (KACST)Inventors: Abdulaziz A Bagabas, Mohamed Mokhtar Mohamed Mostafa, Abdulrahman A Al-Rabiah, Vagif Melik Akhmedov

Patent number: 8101805Abstract: A low-pressure one-step gas-phase process for the production and recovery of methyl isobutyl ketone (MIBK) is disclosed. One-step gas-phase synthesis of MIBK from acetone and hydrogen over nano-Pd/nano-ZnCr2O4 catalyst at atmospheric pressure is used as an example. The said process is designed to recover the additional heat associated with the reactor effluent via heating acetone feed and recycle (mixed acetone) before entering the reactor. A compressor is introduced to the gas-phase process to increase slightly the reactor effluent pressure before this effluent is cooled and fed to a flash drum. The compressed reactor effluent is used to preheat hydrogen feed and recycle (mixed hydrogen) before entering the reactor. The separation scheme of low-pressure one-step gas-phase process comprises of several distillation columns used for MIBK separation and purification.Type: GrantFiled: June 7, 2011Date of Patent: January 24, 2012Assignee: King Abdulaziz City for Science and Technology (KACST)Inventors: Abdulrahman A Al-Rabiah, Abdulaziz A Bagabas, Akhmedov Vagif Malik

Publication number: 20110278039Abstract: An eco friendly radiation cross-linked composition is described that demonstrates excellent resistance to fire and high temperature along with good mechanical properties. The composition which is based on a blend of EVA with a LLDPE, is free of monomer such as vinyl co-agent for radiation cross-linking. The halogen free flame retardant composition is a mixture of 20 to 90% by weight of magnesium hydroxide (powder A) and 90% to 20% of powder B. Preferably the powder B is a double salt of magnesium carbonate and calcium carbonate and the magnesium hydroxide has a specific surface treatment. In addition, 0.5 to 5 parts of flame retardancy auxiliary agents are selected from talc, zinc borate or molybdate derivative. The chemicals used here reduce toxicity in the environment and do not release toxic chemicals to air and soil during fire. The flame retardant cross-linked polyolefin composition is particularly useful for insulating wires and cables.Type: ApplicationFiled: July 25, 2011Publication date: November 17, 2011Applicant: King Abdulaziz City for Science and Technology (KACST)Inventors: Ahmed Ali Basfar, Patrick Noireaux, Arnaud Coudreuse, Roxane Noblat
