Study result suggest: The change of stock in RFCCU directly affect gasoline content. Gasoline content can be reduced through increasing the equilibrium activity of catalyst, controlling reaction level, increasing recirculating rate of gasoline and stability of gasoline level. Conclusions drawn from experiment is that optimization of operating condition has great effect on lowering olefine content of gasoline which can be reduced from 60% to 50%.Reducing reaction temperature is useful for lowering olefine content of gasoline, when the reaction temperature is raised, thermal cracking rate is higher than catalytic cracking rate, so that olefine content is increased. Raising catalyst-to-oil ratio is good for lowering olefine content. With conversion rate increased, the yield of LPG and coke is raised, the yield of gasoline is increased firstly and then decreased slightly, hydrogen transfer index is increased, so the olefine content is decreased.

There are a few defects in existing processes of biomass gasification, for example using air as gasifying medium, N2 and tar content of the gas is high, and the calorific value is as low as 5000kJ/N in3. The technology of a circulating fluidized bed is still tentative at laboratory level. Through direct pyrolyze biomass, we can get product gas with high heating value (l4000kJINm3), but gas yield ratio is low (O.35m3/kg).

The thermal property studies indicate that the mass loss of compound B was 54.39% at 242.2~750℃, and when the temperature was 1000℃, there was 25.11% char residue left, which showed that the title compound has a good thermal stability and char forming capability. Using acetonitrile as the solvent instead of trichloromethane or 1, 2-dichloethane gave higher yield. During the synthesis, the yield was very low when triethylamine was used as acid acceptor alone, and when a little amount of 4-dimethylaminopyridine was added at the same time, the yield could be 81%.
