“…Syngas is a permanent gas such as methane and hydrogen and liquid fuel is a product obtained from the condensation of volatile products [2]. Syngas and liquid fuel can be used as electrical gas engine fuels, integrated with a turbine cycle that convert the fuel energy into electricity [3] on which it has better combustion efficiency compared to direct burning process [4] and very low environmental impact [ 5,6]. The percentage of the results of pyrolysis between solid, liquid and gaseous products is very dependent on the type of pyrolysis process namely slow pyrolysis, fast pyrolysis and flash pyrolysis [7,8].…”

Thermal degradation at 500 o C to a Real Municipal Solid Waste (RMSW) has leave a footprint of problem with very low mass yields of liquid fuel. Therefore, in the presence research, it has been attempted to increase the mass yield of liquid fuel by using Long Catalyzer Downstream (LCD) equipped with top and bottom outlet in stage pyrolysis. Two types of natural catalysts (zeolite and kaolin) that have been activated at 500 o C for 2 hours were used in this experiment. Also, LCD temperatures were varied from 200-300 o C with pyrolizer temperature were hold at 500 o C. The experimental results revealed that there was a significant increase in the mass yield of liquid fuels compared to pyrolysis without catalysts and direct catalyst of pyrolysis. The presence of LCD was making a major contribution to generate secondary cracking and producing more products of short hydrocarbon ranges from MSW feedstock. Among natural zeolite and kaolin catalysts, natural zeolite catalysts have productivity behavior better than natural kaolin. The higher mass yields in liquid fuels have been demonstrated by natural zeolite catalysts.

The use of non-oil Jatropha biomass in the energy mix as a solid fuel offers the most effective ways of utilising such resource. However, available information indicates that biomass has negative inherent properties which lower its fuel value. This negative effect can be improved by slow pyrolysis process called torrefaction where the biomass is heated in the range of 200 °C to 300 °C. In the present investigation the effects of torrefaction temperature on the solid fuel value of different Jatropha biomass materials were determined. Consequently, three types of Jatropha biomass namely; seed cake, stem and fruit cover were considered under five temperature levels (200 °C, 225 °C, 250 °C, 275 °C, 300 °C). Analysis of Variance (ANOVA) revealed that there were significant differences (P > 0.05) in bulk density, hygroscopicity, energy content and ultimate etc. The statistical analysis results indicated that there was biomass type and torrefaction temperature interaction effects on the ultimate analysis, bulk density, hygroscopicity, energy content and energy yield. The interaction effects of the factors under investigation were not observed in mass yield. Increase in torrefaction temperature generally reduced the equilibrium moisture content and volatile matters across the biomass types. However fixed carbon, carbon content, ash content and energy density were increased across the biomass types as the temperature was increased from 200 °C to 300 °C. The torrefied Jatropha seed cake biomass showed relatively enhanced fuel characteristics than the torrefied stem and the torrefied fruit husk when considering the properties under investigation.
