The effect for analyse result exactly was analysed from analysis line,lamp current,combustion controller height and gas/combustion-supporting gas to determine lead in gasolene by atomic absorption spectrometry method,and defined the best operating conditions.
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.
Modern state of the catalytic reforming of petrol fractions.
Diagnostic ratios indicated combustion of wood and coal, emissions from petrol and diesel engines, and dust resuspension as sources that predominantly contributed to the atmospheric PAH concentrations.
Characterization of on-road CO, HC and NO emissions for petrol vehicle fleet in China city
The alkene-rich petrol fraction from refinery fluid catalytic cracking (FCC) has been characterized by GC and GC-MS.
The proposed coating was applied for aromatic hydrocarbons determination in petrol station waste waters.
