RESEARCH OF COKE FORMATION ON HZSM-5 ZEOLITE USED FOR TWO-STAGE GASOLINE SYNTHESIS FROM SYNGAS
IntroductionThe catalytic conversion of syngas into high-quality clean fuels and chemicals is an effective and green process to release the shortage of crude oil. Fischer-Tropsch synthesis (FTS) has been widely used for this conversion, but the product distributions of FTS on iron or cobalt based catalysts obey the Anderson-Schulz-Flory (ASF) polymerization kinetics, resulting in a statistical distribution of hydrocarbons. Therefore, it is necessary to make further transformation of a part of FTS product into the desired fraction. In 1984, the TopsOe integrated gasoline synthesis (TIGAS) process developed by Haldor Tops0e can convert syngas into gasoline via two catalytic stages 1, including oxygenates synthesis and gasoline synthesis. In oxygenate synthesis, one-step conversion of syngas to dimethyl ether (DME) based on a hybrid catalyst which composed of Cu/Zn/Al2O3 and γ-Al2O3 improves the per-pass conversion and reactor productivity, due to the conversion is not limited by thermaldynamic equilibrium as it for syngas conversion to methanol 2,3.
