An increasing the content of C–N=C groups improves the selectivity for the desired product, while an increasing the content of tertiary nitrogen leads to an increased formation of by-products. Nanocomposite catalysts Mg-Al/AC based on Mg-Al-oxide systems (hydrotalcite derivatives) and activated carbon (AC) as a support reveal high activity in the process of gas-phase condensation of ethanol in flow mode to obtain 1-butanol, due to the redistribution of active sites on the catalyst surface and increase their accessibility for the reagents. Composite catalysts for methanol conversion based on ZSM-5 zeolite, carbon nanotubes and alumina have been obtained. The presence of the antibate dependence between Bronsted acid sites concentration and the catalyst selectivity towards ethylene has been established. A reduced graphene oxide has been developed which exhibits high selectivity towards ethylene in selective acetylene hydrogenation in the excess of ethylene and allows to obtain ethylene with a purity of >99% by hydrogenating of acetylene-ethylene mixture with acetylene content of up to 10%. A number of new composites of 3d metal nanoparticles with carbon nanoparticles on porous supports, which are active in the oxidative amination of cyclic ketone with propargylamine, have been synthesized, the yield of the desired product – substituted pyridine – is 34%.
