REACTOR OF CATALYTIC METHANE OXIDATION FROM VENTILATION AIR — FROM LABORATORY TO QUARTER-TECHNICAL SCALE PROTOTYPE

Abstract

The most research efforts in heterogeneous catalysis are directed at understanding the correlations between the catalytic activity of studied contact and its physical-structural properties. One way to address this issue is through examination of specific reaction mechanism which has been of particular interest to many researchers. The most important from these basic studies focus on the effect of variables such as temperature and/or concentration of substrate or product on the reaction rate. In many cases, significant differences in mechanisms may lead to similar microscopic observations, and thus, to similar expressions for the reaction rate. This means that the experimentally determined kinetic parameters usually do not allow firm conclusions on microkinetic mechanism. This problem is especially important for multi-step processes such as the transformation reactions of hydrocarbons, in particular catalytic oxidation. However, it should be noted that any proposed mechanism must be compatible with the evaluated kinetics.
