The catalytic properties of rock from fumarole mouth and condensates of gases of the Kudryavyi volcano

A sample of volcanic rock was shown to catalyze dehydrogenation and dehydra tion of isopropanol. Condensates of volcanic gases of different temperature s were obtained on three carriers, namely, zeolite, gamma -Al2O3, and cybun ite. The largest amount of Re and rare elements was observed on zeolite. Th is catalyst, like that prepared on gamma -Al2O3 and Like the carriers thems elves, was found to possess predominantly dehydrating properties. Catalysts on cybunite dehydrogenated isopropanol to acetone.
