The invention discloses a clean fuel, containing organic chemical components, for a gasoline engine. The clean fuel consists of methanol, gasoline and a cosolvent, wherein the methanol and the cosolvent respectively account for 5-30 percent and 0.5-4 percent by volume of the total volume of ...
Experimental results indicated that conjugated dienes in spite of its very small content in naphtha played the most important effect on the stability of naphtha. After the conjugated dienes have been removed, the stability would increase significantly. A high amount of mono-olefins is another ...
Second, we use a fuel composition-based approach to quantify uncombusted fuel components in exhaust using the emission factor for total uncombusted fuel in exhaust together with detailed chemical characterization of liquid fuel samples. There is good agreement between the two methods except for ...

An example is the platinum dispersed on alumina used in the gasoline reforming. The active agent is the component(s) that causes the main catalytic action. Without it, the catalyst will have no effect. A promoter is a substance added into the catalyst to improve either of the activity, ...
Simon:Last year there were some tremendous repercussions. Europe exports a lot of finished gasoline and components to the U.S., particularly the U.S. East Coast. And the extreme values that we saw last year were reflected in pooling up the values of both gasoline and blending component...

Not only can OH· form carboxyl groups by reacting with oxygen in air or solution, but also further dissociate with other components to form epoxy groups. The gas-phase oxidants mainly include ozone, oxygen, air, water vapor, carbon dioxide, etc. Due to differences in the thermal stability ...
(OC) were determined in the filter samples.The mean PM1.0 mass concentration was 149.7 μg m-3.The total concentrations of 11 ions were 46% of PM1.0 mass concentration,indicating that water-soluble ions were the major components of submicron particles.The average OC and EC concentrations were...
In general, the overall chemical equation for complete combustion of hydrocarbons with air can be written as CxHy+x+y4O2+3.76N2→xCO2+y2H2O+3.76x+y4N2 Typical fuels include hydrogen, propane, and gasoline. Choice of fuel often depends on fuel storage constraints, reaction rates, and ...
