The effect of initial MBY concentration, hydrogen partial pressure, reaction temperature on activity and selectivity to MBE was studied for three microcapillaries coated with different catalysts. The most noticeable impact was observed for the catalyst composition such as Ce-doping and Zn addition to Pd nanoparticles and can be explained by the different strengths of MBY adsorption. The catalyst activity increases in the series: Pd/TiO2 < Pd80Zn20/Ti0.95Ce0.05O2 < Pd/Ti0.95Ce0.05O2, while the adsorption constant of MBY and selectivity to 2-methyl-3-buten-2-ol (MBE) decline. The catalytic performance also depends on test duration and oxidation-reduction treatments. The highest yield of MBE (95.8 %) at 99 % conversion on Ce-doped coatings was obtained on Pd50Zn50/Ti0.95Ce0.05O2 coating after 68 h on stream.",
