Hydrogenation of crotonaldehyde in a gas phase at atmospheric pressure over Ru/support catalysts was studied. Ruthenium nitrozyloazotane Ru(NO)(NO3)3 and three supports: alfa-Ga2O3 (60.4 m2/g), beta-Ga2O3 (2.2 m2/g) and alfa-GeO2 (3.8 m2/g) were used for catalyst preparation with the nominal ruthenium content 5 wt. % and for the catalysts supported on alfa-Ga2O3 also 2 and 1 wt. %. The row of the catalytic performance of catalysts is as follows: 5 wt.%Ru/alfa-Ga2O3>5wt.%Ru/alfa-Ga2O3>5wt.%Ru/alfa-GeO2. The best catalyst, 5 wt. % Ru/alfa-Ga2O3, shows high selectivity to desired product-crotyl alcohol (above 85%) with the activity ca. 300 mi mol s–1 gRu
