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.
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.
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.
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.
The acid and catalytic properties of high-silica zeolites of ZSM-5 type, modified with alkalineearth metal cations in pyrolysis of straight-run naphtha, were studied.
A comparative study was performed of changes in the composition, structure, and catalytic activity of catalysts in selective hydrogenation of C5-C9 fraction of pyrolysis naphtha.
Three cases are reported, one of agranulocytosis with monocytosis and two of acute leukaemia of which the first was caused by radioactive iodine and the second by gasolene.
