Description
This study investigates the characteristics of microwave-assisted pyrolysis applied to rice husk (RH), teak wood powder (TW), and their blends, with the aim of assessing the impacts of varying raw material composition ratios and microwave power settings on the following parameters: (1) the temperature profiles during pyrolysis, (2) the yield of products generated, and (3) the calorific value of the resultant biochar. Experimental procedures involved altering the composition ratios of RH to TW to include 100:0, 75:25, 50:50, 25:75, and 0:100. Microwave power was also varied across three settings: 450 W, 600 W, and 800 W. The results demonstrated that the fastest pyrolysis processes occurred at a 75:25 ratio under 450 W and at a 50:50 ratio under both 600 W and 800 W. The maximum yield of products was observed at a 25:75 ratio under 450 W and 800 W, and at a 50:50 ratio under 600 W. Moreover, the highest calorific value in the biochar was achieved using a 0:100 ratio at an 800 W power setting. These findings highlight the significant role that both raw material ratio and microwave power settings play in influencing the operational efficiency and output characteristics of microwave-assisted pyrolysis.
