| Abstract | This work aims to prepare activated carbon from charcoal of the wood of M. calabura and employ as a support for nickel catalyst. The charcoal was obtained from an Iwasaki kiln and activated by CO2. Then, the surface of activated carbon was modified by air zero to create acid functional groups. The polyaromatic-like structure and their functional groups of the activated carbon were characterized by FTIR and CHNO analysis. The thermal stability was carried out by TGA analysis. The surface area of sample was estimated by BET from N2 adsorption-desorption analysis. The activated carbon after modification had higher acid functional groups than the parent charcoal. The BET surface area decreased after modification but the thermal stability did not change after CO2 treatment. After impregnated with nickel precursor, the structure, acidity and basicity of the catalyst were analyzed by XRD, NH3-TPD and CO2-TPD, respectively. Nickel nanoparticles were produced on activated carbon. The catalytic screening of Guerbet reaction to produce n-butanol from ethanol conversion was performed under autogeneous pressure at 240 ?C for 6 h. The nickel supported on activated carbon showed higher ethanol conversion than the unsupported nickel nanoparticles. |
