- Description
- In moving towards green energy and technology, many efforts had been carried out to make use of renewable sources to generate energy. Oil palm residual is one of the sustainable biomass for bioenergy in Malaysia. As the amount the residual specifically oil palm fronds (OPF) left in the plantation after harvesting is tremendous and their decomposition takes time, researches have been done to make use of the OPF as source of biomass. Meanwhile, gasification of biomass is becoming more popular in generating energy as it leaves less environmental concerns compared to combustion. This work proposes an alternative model of biomass gasification system using OPF as biomass material and also the analysis of the effect of different operating conditions on the syngas performance. The main advantage of this work is the estimation of the system’s performance such that it can be computed without developing the prototype system; which involves spending a certain amount of cost. The chemical properties of the OPF were initially studied before the gasification system can be modelled. The gasification system was modelled based on four zones in a downdraft gasifier which are drying zone, pyrolysis zone, oxidation zone, and lastly reduction zone. In specific, the chemical reactions occur in each zone were balanced using inspection method and were used to model each zone. Then, proper percentages of elements involved were determined through trial and error method after the system was modelled in MATLAB Simulink. The model also takes into consideration the moisture content in the OPF as well as the air fuel ratio. It is found that the performance of the syngas increased with decreasing percentage of moisture content. Not only that, it is found that the syngas produced has high performance at low air fuel ratio. The syngas has high composition of combustible gases, calorific value and energy at low OPF moisture content and air fuel ratio
