The preparation of activated carbon from palm kernel shell for methane adsorption was studied. Taguchi orthogonal array design was employed to optimize the preparation of activated carbon. The statistical results show that the optimized conditions are the impregnation ratio of 0.55, the activation temperature of 900 oC and the activation time of 150min. The impregnation ratio has the most influence on methane adsorption based on S/N ratio analysis. The mathematical model was developed using regression analysis as a function of independent variables. The results of experiment using optimum conditions fall within the predicted value obtained from the developed model. Activated carbon prepared at optimum conditions which have the highest BET surface area of 1,548.0m2/g and the total pore volume of 1.0 cm3/g recorded the highest methane uptake compared to other conditions. The equilibrium data of the adsorption characteristic fitted favourably to the Freundlich isotherm.

The objective of this study is to assess the green house gas (GHG) emission for the production of bio-oil from oil palm biomass and its utilization for 10 MW power generation by evaluating the life cycle carbon footprint analysis. The life cycle GHG emission assessment includes four main stages, which cover the oil-palm cultivation,palm oil mill operation, biomass transportation and pyrolysis process for the production of bio-oil and its utilization for 10MW power generation. The results obtained suggest that the palm bio-oil has potential as a carbon neutral renewable energy source in the future. More importantly, it has no negative impact on the environment as the amount of CO2 emitted to the atmosphere during combustion of this fuel is lower than that of the CO2 absorbed from the atmosphere during cultivation stage.
