thylene is generally produced by thermal cracking of naphtha in the
process involving a complex network of radical reactions resulting
in a broad product distribution. The 1,3-butadiene, needed to rubber
manufacturing, is obtained as by-product of the process. As a recent
development, the oxidative dehydrogenation of ethane is getting
to become the prevailing ethylene production technology, resulting
in shortage on the butadiene market. Alternative, environmentally
friendly butadiene production technologies are sought for the
production of 1,3-butadiene from biomass-derived feedstock, such
as bioethanol, attracts increasing academic and industrial interest.
The transformation, leading from ethanol to butadiene must involve
consecutive reactions, such as, dehydrogenation, hydrogenation, C-C
coupling, and dehydration. Our research is focused on the catalytic
mechanism of this complex transformation. The reaction was tested
over three MgO-SiO
2
catalysts, such as, natural and synthetic talc and
a preparation, obtained by wet-kneading MgO precipitate and SiO
2
nanopowder. The MgO-SiO

material was doped by ZnO, In

and the effect of doping on the product selectivity was investigated.
The oxide catalysts were characterized by NMR and XPS methods.
The surface basicity of the catalysts was probed by CO
2
adsorption,
determined by temperature-programmed CO
2
desorption method. Our
presentation will discuss the effect of catalyst structure and basicity
on the reaction pathway and product yield in the ethanol-to-butadiene
reaction.
