The paper intends for art of running heterogeneous-catalytic chemical reactions with high efficiency using column catalytic reactor with fixed catalyst layer. Described are potential possibilities of this undervalued apparatus to satisfy conditions for selective running of first step in multistep irreversible or reversible reactions in liquid-gas/vapor flow. Minor changes of working regime and construction of the apparatus discussed with the aim to increase the indexes. The idea of these changes is to suppress side reaction steps using due space localization and segregation of reaction participants. As a result, the needed reagents only have possibility for good contact with catalyst and each other. These features may straightly relate to reactionrectification, but realizes much cheaper. The examples chosen for demonstration are Ipatieff’s alkylation of benzene with propylene on “solid acid” and so called “selective hydrogenation” of acetylenes and conjugated dienes.
