Studies on the Influence of Various Metabolic Uncouplers on the Biodegradation Rate of Toluene in a Biofilm Bio-Filter Reactor
Biological inhibition of air pollution has vast advantages over physicochemical methods. One of the biggest challenges faced by researchers with traditional bio-filter in controlling Volatile Organic Compounds (VOCs) such as Benzene, Toluene, Ethylbenzene, and Xylene (BTEX) is, low degradation rate (elimination capacity) and accumulation of very high biomass. The use of metabolic uncouplers...
متن کاملZeolite catalyzed alkylation of toluene by alcohol
Vapor-phase methylation of toluene using methanol and its isopropylation with 2-propanol has been investigated ina down flow reactor under atmospheric conditions using N2 carrier over a series of surface modified andunmodified ZSM-5 (Si/Al= 60-170) loaded with H3PO4, differing in the external surface treatment of the zeolites.The feed molar ratios of toluene/methanol and toluene/2-propanol were...
متن کاملThe effect of respiratory exposure to benzene, toluene, xylene and ethyl benzene on the spirometric indices among the petroleum products loading workers
Abstract Background and Aim: Benzene, toluene, xylene and ethyl benzene (BTEX) are the most important aromatic compounds in petroleum products. BTEX compounds due to their high vapor pressure, easily change to gas form and mixed with ambient air. Petroleum products loading workers are exposed to these compounds by the inhalation of BTEX compounds. The aim of this study was to evaluate the ef...
متن کاملCancer Risk Assessment Benzene, Toluene, Ethylbenzene and Xylene (BTEX) in the Production of Insulation Bituminous
Benzene, Toluene, Ethyl Benzene and Xylene are volatile organic compounds (VOCs) with approximately similar physical and chemical characteristics. Benzene and Ethyl-benzene are known carcinogen as well as they affect the circulatory, nervous, and reproductive and respiratory systems. Toluene and Xylene also damage the nervous and reproductive systems. The main purpose of this study is to determ...
متن کاملThe effect of high power ultrasound on an aqueous suspension of graphite.
Ultrasound treatment was used to study the decrease of the granulometry of graphite, due to the cavitation, which allows the erosion by separating grains. At a smaller scale, cavitation bubble implosion tears apart graphite sheets as shown by HRTEM, while HO(*) and H(*) radicals produced from water sonolysis, generate oxidative and reductive reactions on these sheet fragments. Such reactions fo...
