ИСТИНА

Unsaturated hydrocarbons are the main feedstock for a wide range of polymer materials. One of the most promising methods for their production is the catalytic dehydrogenation of light paraffins, including propane. The industrial catalysts usually contain Pt or CrOx particle supported on Al2O3. Platinum-based catalysts are expensive and easily deactivated, while high chromium content is hazardous due to possible presence of toxic Cr+6 compounds. ZrO2-based catalysts modified with silica and small amount of CrOx as an active component are promising for non-oxidative propane dehydrogenation.
