最近在新西兰召开的从天然气制燃料和化学品的国际会议上,引人注目的工艺如下。(1)美国马萨诸塞理工学院的赛耶教授研究了甲烷催化反应的机理,在试验中,使Ni(Ⅲ)结晶表面于10~(-6)mmHg 的压力和46K 的温度下保持在甲烷气流中,在此条件下镍的表面蒙上了甲烷单分子膜,如使其瞬间接触氩气流,则甲烷从镍的表面脱落,Ni(Ⅲ)的结晶温度上升到74 K。这种甲烷分子的
At the recent international conference on natural gas-based fuels and chemicals held in New Zealand, the compelling process was as follows. (1) Professor Saier of Massachusetts Institute of Technology studied the mechanism of methane catalytic reaction. In the experiment, the Ni (Ⅲ) crystal surface was kept in the methane gas stream under the pressure of 10 ~ (-6) mmHg and temperature of 46K Under this condition, the surface of nickel is covered with a monolayer of methane. If argon gas is instantaneously contacted with methane, the methane will fall off from the surface of nickel and the crystallization temperature of Ni (Ⅲ) will increase to 74K. This kind of methane molecule
