摘要：
The effect of hydrogen during the pre-treatment stage of CoAPO-5 and CoAPSO-5 molecular sieves on the status of cobalt ions has been studied. Cobalt migration from framework to extra framework positions and formation of metal cobalt is observed. The conversion of methanol is used as a model reaction for characterization the changes in the CoAPO-5 and CoAPSO-5 molecular sieves. The role of hydrogen upon the different pathways of methanol conversion is also tested. (C) 1998 Elsevier Science B.V.
