Study on reformulation of fluid catalytic cracking gasoline and increasing production of light olefins
      
The experimental results showed that FCC gasoline was obviously reformulated under appropriate reaction conditions.
      
The olefins (olefins with C atom number above 4) content of FCC gasoline was markedly reduced, and the aromatics content and octane number were increased.
      
The upgraded gasoline met the new standard of gasoline, and meanwhile, higher yields of light olefins were obtained.
      
Furthermore, higher reaction temperature, higher mass ratio of catalyst to oil, higher mass ratio of water to oil, and lower space velocity were found to be beneficial to FCC gasoline reformulation and light olefins production.
      
experimental results show that the spray characteristics of methanol and ethanol had displayed the same trends as that of gasoline.
      
Experiments also showed that methanol had the largest cone angle, while ethanol and gasoline presented almost the same cone angle.
      
Simulation results indicated that methanol and ethanol had a slightly larger Sauter mean diameter (SMD) than that of gasoline with swirl injector.
      
Identifying combustion intermediates in premixed MTBE/gasoline/oxygen flame probed via synchrotron radiation
      
In this paper, the results to identify combustion intermediates in low-pressure premixed gasoline/oxygen flame with the synchrotron radiation were reported.
      
Based on the results obtained, the formation process of five products and the difference between gasoline/oxygen and MTBE/gasoline/oxygen flame were emphatically analyzed.
      
The results achieved provide data basis for the analysis of intermediates and radicals in flame, and are helpful to establish the kinetic modeling of gasoline/oxygen and MTBE/gasoline/oxygen flames.
      
multicycle pulse detonation engine (PDE) model, and liquid fuel (gasoline) was used.
      
Control of homogeneous charge compression ignition combustion in a two-cylinder gasoline direct injection engine with negative v
      
In this paper, HCCI combustion was studied in a two-cylinder gasoline direct injection (GDI) engine with negative valve overlap (NVO).
      
A two-stage gasoline direct injection strategy combined with negative valve overlap was used to control mixture formation and combustion.
      
The gasoline engine could be operated in HCCI combustion mode at a speed range of 800-2 200 r/min and load, indicated mean effective pressure (IMEP) range of 0.1-0.53 MPa.
      
The catalyst performance was tested on a real lean-burn gasoline engine.
      
Other important sources are gasoline evaporation, painting, and solvents.
      
The objective of this study is to carry out an economic, environmental and energy (EEE) life cycle study on natural gas-based automotive fuels with conventional gasoline in an abundant region of China.
