| 英文摘要 | the catalytic activity, thermal stability and carbon deposition of various modified nio/gamma-al2o3 and unmodified nio/gamma-al2o3 catalysts were investigated with a flow reactor, xrd, tg and uvrrs analysis. the activity and selectivity of the nio/gamma-al2o3 catalyst showed little difference from those of the modified nickel-based catalysts. however, modification with alkali metal oxide (li, na, k) and rare earth metal oxide (la, ce, y, sm) can improve the thermal stability of the nio/gamma-al2o3 and enhance its ability to suppress carbon deposition during the partial oxidation of ethane (poe). the carbon deposition contains graphite-like species that were detected by uvrrs. the nickel-based catalysts modified by alkali metal oxide and rare earth metal oxide have excellent catalytic activities (c2h6 conversion of similar to 100%, co selectivity of similar to 94%, 7x 10(4) l/(kg h), 1123 k), good thermal stability and carbon-deposition resistance. |
