| Abstract: | Ni/silicalite 2 is a desirable catalyst for the syngas production from reforming light alkanes with CO 2. La 2O 3 is an effectual promoter to the Ni/Si 2 catalyst for this process, with the addition of La 2O 3 promoter to the Ni/Si 2 catalyst, both the catalyst activity and the syngas yield increase obviously. Furthermore, K 2O is an another practical promoter to the La Ni/Si 2 catalyst for syngas formation from the reformation of light alkanes with CO 2, resulting in the increments of syngas selectivity and CO 2/CH 4/C 2H 6 conversions. |
