Thanks to separation of catalyst layers with Pd and Ni particles, the possibility of minimizing the content of costly metals in bimetallic catalysts was evidenced, and the synergy of two zeolite components in the formation of hexane isomers was shown, which is more effective in the case of their isotropic distribution in the catalyst. The lower efficiency of the bizeolite catalyst with active γ-Al2O3 compared to that containing α-Al2O3 was observed and explained by the formation of surface Brønsted acid sites in the latter, which are not present in γ-Al2O3. A sample was obtained, the catalytic characteristics of which combine a high yield of hexane isomers, comparable to that demonstrated by monozeolite mono- and bimetallic catalysts with a similar content of the metal component, with a significantly higher dimethylbutane yield and a reduced temperature of the maximum iC6-yield. The structure of synthesized biosynthetic surface-active agents was investigated by physico-chemical methods and a high conversion of the substrate and passage of the amidation reaction were confirmed. According to the results of studies of phase transitions, alkanolamides of highly fatty acids based on phosphatide concentrate and technical animal fat have an amorphous structure and don’t show clear crystal ordering. The use of solvents and vacuum made it possible to soften the conditions for the synthesis of bioSAA and reduce the temperature by 10-20 ºС. The use of catalytically active alkaline components in the reactions of the synthesis of surface-active agents reduced the reaction time by 1-2 hours and the temperature by 10-30 ºС. Research on the temperature regularities of the processes of thermal decomposition of synthesized SAA established their temperature limit for use in technical processes up to 180 ºС.
