Mesostructured cellular foam (MCF) silica materials with different pore topology prepared at various amounts of TEOS (9.2; 25; 32 ml) were used as supports for incorporation of nickel. Nickel incorporated MCF catalysts were prepared using deposition-precipitation at 90 oC and followed by reduction process at 550 oC. The influence of different pore topology of MCF on characteristics of the nickel incorporated MCF catalysts was studied using nitrogen physisorption, TEM, and SEM-EDX techniques. Activities of the catalysts were tested for decarboxylation of palmitic acid in solvent free condition at reaction temperature of 300 oC under nitrogen flow for production of n-pentadecane hydrocarbon fuel. The results show that NiMCF-9.2T(R) catalyst using MCF-9.2T support prepared at TEOS amount of 9.2 ml achieved the highest palmitic acid conversion and n-pentadecane yield. The highest activity was mainly attributed to the high nickel composition and a fine nickel particle dispersed in the NiMCF-9.2T(R) catalyst.
