| dc.description.abstract | The field practice was conducted in Central Luzon State University. The field practice was composed of two activities; (1) production of biochar as alternative fuel using pyrolysis carbonization method and (2) production of hydrochar using hydrothermal conversion process. Pyrolysis as a biomass conversion technology is particularly low suited to moisture organic wastes. Thus, if biochar proves a valuable by-product, it could induce more use of pyrolysis conversion that would be applicable to over half the unutilized wastes identified in the state biomass inventory. The objectives for the production of biochar as alternative fuel using pyrolysis carbonization method were to (1) produce fuel pellet from biochar of cacao pod husk, (2) determine the physical characteristics of pelletized cacao pod husk in terms of shatter resistance and durability. The objectives for the production of hydrochar using hydrothermal conversion method were assist in the preparation and hydrothermal conversion (HTC) process of cacao pod husk. The treatments in activity 1 were made in evaluation of the physical characteristics of CPH pellet were different binder proportion and different compaction pressure were used as parameters. The binder is used to strengthening and binding of pellet, 1:15 and 1:20% binder proportion were used in the study. Compaction pressure of 1, 2, 3, 4, 5 and 6 kg/cm² were used to test the strength of the pellet. The treatments were analyzed using Completely Randomized Design (CRD) and comparison of means was done using Least Significant Difference (LSD). Hydrothermal carbonization method was done using a 20 liter capacity hydrothermal reactor and the cacao pod husk were carbonized for 12 hours with a temperature of 180°C to produce hydrochar. Results show the significant differences and their effects on the response variables. The higher resistance values as indicator of durability with 97.4 % after drop test were observed on higher percentage of molasses binder (20%) and higher compaction pressure 6 kg/cm². Pellet samples subjected to 2 kg/cm² compaction pressure resulted to the highest flame temperature of 185°C. Pellet subjected to 20% molasses and compacted at 1 kg/cm² resulted to the highest coal temperature of 416°C. Ash weight of pellets subjected to 5 kg/cm² compaction pressure resulted higher mean weights of 3.5 grams. Lab test results of the carbonized cacao pod husk have a higher heating value of 24.55MJ/kg, a moisture content of 1.55%, a fixed carbon content of 48%, and ash content of 23.54%. The moisture content of the hydrochar was found to be 12.35% with volatile combustible matter of 58.59%, fixed carbon of 8.43%, and an ash content of 32.98%. | |
