<p>The present invention relates to safety catalyst systems and their use in chemical reactions carried out in the gas phase, wherein the safety catalyst system comprises pelleted catalyst held loose in and throughout the holes and folds of a folded or rolled up metal foil net which is inside a container having holes for the inflow and outflow of gases. The safety catalyst system of the invention does not allow the formation of localized hot-spots or allow free catalyst dust to escape from the system, both of which are known disadvantages of prior art systems. …<??>The present invention also relates to a method of catalysing chemical reactions in the gas phase in the presence of such a safety catalyst system.</p> |
