| 内容記述 | Biofuels can help in solving some of the global energy related problems. Therefore, how to derive biofuels from various resources has earned a great deal of attention. In this respect, thermochemical decomposition technology called pyrolysis can be used. This study, in particular, addresses the derivation of biofuels and other chemical substances from the selected biomass solid wastes: jute stick, tamarind seed, and cedar wood using a fixed-bed pyrolysis unit. Note that jute stick is available in India, Bangladesh, and China, whereas tamarind seed is available in tropical countries located in South East and South Asia, and cedar wood is available in Japan. The selected biomass solid wastes have been characterized by using the proximate, ultimate, gross calorific value, and thermo-gravimetric analyses. The analyses help determine whether the selected biomasses are suitable for pyrolysis (i.e., a thermal decomposition in partially/completely absence of oxygen). Thermal gravimetric (TG) and differential thermal gravimetric (DTG) behavior of selected three biomass have been investigated under nitrogen atmosphere at heating rates 10 and 60°C/min over temperature range 30-600°C. The percentage weight loss was higher for Japanese cedar wood and lower for tamarind seed for both heating rates. Using the results of these analyses, the kinematic models have been developed for the respective solid wastes for predicting TG and DTG data. The models are based on the Arrhenius Law, and exhibit a good correlation with the experimental results. In the next phase of this study, the particles of the selected biomass solid wastes (hereinafter referred to as feedstock) have been processed using pyrolysis. A fixed-bed pyrolysis unit has been used to obtain the biofuels and other chemical substances from the feedstock. The pyrolysis performance of the respective solid wastes (i.e., liquid yields) have been determined varying such conditions as fixed-bed reactor temperature, feedstock size, nitrogen gas flow rate, and running time. The maximum liquid yields are about 50%, 45%, and 48% (in terms of weight fraction) for the feedstock of jute stick, tamarind seed, and cedar wood at the fixed-bed reactor temperature equal to 425°C, 400°C, and 450°C, respectively. The other conditions corresponding to maximum liquid yields for all three types of feedstock are as follows: nitrogen gas flow rate is equal to 6 l/min, feedstock size is in the range of 1180 μm to 1700 μm, and running time is 30 min. Liquid products obtained at these conditions were characterized by physical properties, chemical analysis and GC-MS techniques. The results show that it is possible to obtained liquid products that are comparable to petroleum fuels and valuable chemical feedstock from the selected three biomass if the pyrolysis conditions are chosen accordingly. |
