Biodiesel is an alternative biodegradable and nontoxic fuel, which is free of sulfur and aromatics. Several non-edible oils such as Madhuca indica, Jatropha curcas, Pongania pinnata and Calophyllum inophyllum L. has been investigated experimentally, are found to be suitable for biodiesel production. In this study, Response Surface Method (RSM) based on Central Composite Design (CCD) was applied to...
Hydrogen is a potential alternative energy source over fossil fuels when produced from biomass via thermal conversion process. This is indeed very attractive as Malaysia is having abundant biomass resources. In this paper, a mathematical model is developed to predict the maximum possible attainable composition of the product gas from a thermal conversion process, i.e. gasification, of palm kernel...
Biomass steam gasification with in-situ carbon dioxide capture using CaO exhibits good prospects for the production of hydrogen rich gas. The present work focused on the determination of reaction rate kinetics for hydrogen production from oil palm waste steam gasification using optimization approach in MATLAB. The kinetics parameters were calculated by fitting experimental data to kinetics model and...
The calorific value (CV) of syngas produced from gasification of solid biomass varies depending on the type of biomass as well as the gasifier type. Moreover, the interdependent operating conditions like reactor temperature, moisture content of biomass, and air fuel ratio play a major role in the composition as well as calorific value of syngas. The gasification of oil-palm fronds (OPF) is not studied...
Renewable energy (RE) has been declared as the fifth fuel of Malaysia in addition to oil, gas, coal and hydropower. One of RE which is hydrogen and has became an alternative fuel for transportation instead of petroleum. For sufficient hydrogen storage, the system requires an inexpensive, safe, low weight tank, comparable in to a gasoline tank with capability of quick loading and unloading hydrogen...
Hydrogen has emerged as one of the sustainable fuels in the next future that can be used in internal-combustion engine. Hydrogen produced from catalytic gasification of biomass generates clean and higher efficiencies automotive fuel. The use of catalyst in the biomass gasification is effective to elevate hydrogen content and to reduce tar formation. This work presents the development of Fe supported...
Thermal decomposition of palm oil wastes i.e. palm kernel shell (PKS) and palm oil fronds (POF) was studied using thermogravimetric analysis (TGA) under non-isothermal conditions. Thermogravimetric (TG) and its first derivative profiles were depicted to show different breakdown regions for PKS and POF. The decomposition region of hemicellulose, cellulose and lignin was identified. Kinetic parameters...
