Selective reduction of NO by CH4 in the presence of excess O2 has been studied on cobalt-ion-exchanged synthetic clinoptilolite (Co-CLI) zeolite. The catalytic results are compared with those obtained from Co-ZSM-5 and Co-FER, the two most widely studied catalysts for this reaction. At T ≥ 500 ºC, Co-CLI is much more active for NO reduction than Co-ZSM-5, but it is less active than Co-FER. However,...
A pure, highly crystalline clinoptilolite (CLI) zeolite with a Si/Al ratio of 5.8 has been synthesized using a small amount (1%) of seed crystals and tested as a catalyst for the skeletal isomerization of 1‐butene at 623–723 K at atmospheric pressure. The catalytic results are compared to those obtained from a ferrierite (FER) zeolite with a Si/Al ratio of 7.6. It is found that selectivity for isobutene...
