Popis: 1. An investigation has been carried out into the effect of the value of the compression pressure (in the range 2,000–20,000 atm) on the structure of compressed alumina-molybdenum oxide catalyst and on its productivity, specific activity, and stability in the reactions of dehydrocyclization of heptane and dehydrogenation of cyclohexane. 2. It has been shown that increase in compression pressure leads to increase in the productivity and decrease in the specific activity of the catalyst (to an equal extent for both of the investigated reactions). 3. It has been found that the stability of compressed alumina-molybdenum oxide catalyst increases with the compression pressure (also to an equal extent for both of the investigated reactions). 4. X-Ray investigation has not revealed any changes in the priamry (X-ray) structure of the catalyst after it has been subjected to a high hydrostatic pressure.
