Two-stage riser catalytic cracking of heavy oil for maximizing propylene yield (TMP) process proposed by State Key Laboratory of Heavy oil Processing, China University of Petroleum, can remarkably enhance the propylene yield and minimize the dry gas and coke yields, and obtain high-quality light oils (gasoline and diesel). It has been commercialized since 2006. Up to now, three TMP commercial u...
zno and zno: mn nanocrystals were synthesized via reverse micelle method. the structural properties of nanocrystals were investigated by xrd. the xrd results indicated that the synthesized nanocrystals had a pure wurtzite (hexagonal phase) structure. resistive gas sensors were fabricated by providing ohmic contacts on the tablet obtained from compressed nanocrystals powder and the installation ...
consumption of leaded gasoline in iran cause to emit lead compounds in ambient air of gasoline stations and is known to effect on workers health in these locations. the objectives of this study were assessment of ambient lead levels and blood lead levels of gasoline station workers in hamadan city, iran. for this purpose, 82 samples were obtained in ambient air of gasoline station locations. se...
Di methyl carbonate (DMC) has a lot of good properties to be used as a blend with gasoline. In order to improve the efficiency, combustion stability and emission performance of a spark ignition engine, oxygenated fuel (DMC) is added to a gasoline. In this experimental work, the effect of using 100% gasoline and gasoline-DMC blends (D5, D10, D15 and D20) on four cylinder engine performance and e...
Introduction Gasoline is a complex solution of different hydrocarbons. Naturally occurring petroleum contains aromatic hydrocarbons, a class of unsaturated hydrocarbons that includes benzene, toluene, ethylenzene, and xylene (collectively known as BTEX). Since the EPA banned lead additions to gas in 1973, aromatic hydrocarbons were added to increase the octane concentration, thereby maximizing ...
Methane in soil gas may have undesirable consequences. The soil gas may be able to form a flammable mixture with air and present an explosion hazard. Aerobic biodegradation of the methane in soil gas may consume oxygen that would otherwise be available for biodegradation of gasoline hydrocarbons. The consumption of oxygen by methane may increase the chance of completing a vapor intrusion pathwa...
BACKGROUND Gasoline station workers are exposed to volatile organic compounds such as benzene, toluene, ethylbenzene and xylene (BTEX). OBJECTIVE To determine the level of exposure to BTEX compounds among gasoline station workers and measure the roadside concentrations of these compounds in the inner and outer areas of Bangkok, Thailand. METHODS 49 workers at 6 gasoline stations in the inne...
The influences of gasoline on the emission of polycyclic aromatic hydrocarbons (PAHs) from gasoline engine are investigated. These fuels included C92-Leadfree Gasoline (C92-LFG), C95-Leadfree Gasoline (C95-LFG), C98-Leadfree Gasoline (C98-LFG), these are Reforming Gasoline, T92-Leadfree Gasoline (T92-LFG), T95-Leadfree Gasoline (T95-LFG), T98-Leadfree Gasoline (T98-LFG), these are total-PAHs co...
Exhaust gases from an internal combustion engine, alternatively powered by gasoline or by liquefied petroleum gas, were analysed for polynuclear aromatic hydrocarbons. The engine operated a lift truck for the handling of warehouse goods. A combined condensation-filtration apparatus was constructed for sampling of the exhausts. The basic steps of the analytical procedure are summarized here. Sev...
The addition of ethanol into gasoline has long been a method to help the hydrocarbons of gasoline burn smoother in an internal combustion engine by adding oxygen into the fuel. Gas stations list ethanol content in gasoline can be up to 10% ethanol but no more than 10% ethanol. By using the methods of standard addition, using known concentrations and volumes of spikes of ethanol into the gasolin...
