چکیده انگلیسی
As an effective promoter for K/MoS2 catalyst, the addition of nickel would result in a higher selectivity of hydrocarbons due to the presence of separated NiSx phase. In the present paper, a highly homogeneous and dispersed US-Ni/K/MoS2 catalyst was prepared by ultrasonic technology under non-water environment. Compared with conversional Ni/K/MoS2 catalyst prepared by co-precipitation method, US-Ni/K/MoS2 catalyst showed higher productivity of alcohols with the lower selectivity of hydrocarbons. The inhibition of methanation of Ni promoter should be ascribed to the high homogeneity of US-Ni/K/MoS2 catalyst, in which the formation of separated nickel sulfides was impressed remarkably.
