| 英文摘要 | selective synthesis of gasoline-range hydrocarbons (c-5-c-12) was investigated in a fixed-bed micro reactor using two series of co2-containing syngas with various mole co2/(co + co2) and h-2/(co + co2) ratios, where fischer-tropsch synthesis(fts) and in situ hydrocracking/hydroisomerization were performed over bifunctional co/sio2/hzsm-5 catalyst. co2 was converted at 0.15-0.55 of co2/(co + co2) ratio under h-2-rich condition (h-2/(co + co2) = 2.0), highest conversion of 20.3% at 0.42. further increasing co2 content decreased co2 conversion and quite amount of co2 acted as diluting component. for the syngas with low h-2 content or h-2/(co + co2) ratio (<1.85, h-2/co = 2.0), the competitive adsorption of co, h-2 and co2 resulted in low co, co2 and total carbon conversion, which was 57.9%, 12.7% and 31.4% respectively at 0.74 of h-2/(co +co2) ratio(h-2/co/co2/ n-2=40.8/20.4/34.8/4). fts results indicated that high h-2 content and proper h-2/(co + co2) ratio were favorable for the conversion of co2-containing syngas. more than 45% selectivity to gasoline-range hydrocarbons including isoparaffins was obtained under the two series of syngas. it was also tested that the catalytic activity of co/sio2/hzsm-5 kept stable under co2-containing syngas(< 7.5%). and the quick catalytic deactivation under high co2 containing syngas(h-2/co/co2/n-2= 45.3/23.2/27.1/3.06) was due to carbon deposition and pore blockage by heavy hydrocarbon, tested by thermal gravimetry, n-2 physisorption and scanning electron microscopy(sem).
