Study on catalytic hydrogenation of sulfolene over La/Ni-MoS_2 composite

Effect of ultrasonic waves,premonitory LixMoS2 and La/Ni-MoS2 composite were prepared by n-butyl lithium intercalating in the MoS2 layers,using the single-molecular-layer exfoliated-restacked technology.The effect of catalyst on the performance was investigated with catalytic hydrogenation of sulfolene over La/Ni-MoS2 composite as probe reaction.The catalyst evaluation results show that the optimum atomic ratio,hydrogen pressure and reactive temperature are n(La)/n(Ni)=0.05,2.5MPa and 60℃,respectively.Under such condition,conversion of sulfolene was 99.8%,the yield of sulfolane reached 95.5%.This study could provide experimental data for the technical reform of industry equipment.
