optimasi produksi bio-oil hasil pirolisis biomassa ampas tebu (sugarcane bagasse) menggunakan katalis nImO/nza dengan pendekatan rsm

Indonesia has great potential for renewable energy development, including biomass, which can be utilized as an alternative energy source. Bagasse, an abundant agricultural waste, is one type of biomass that has not been optimally utilized. Through the pyrolysis process, bagasse can be converted into high-value products such as bio-oil, biochar, and gas. This study aims to determine the optimum operating conditions for bio-oil from the bagasse pyrolysis process by varying the pyrolysis temperature (A), metal loading percentage (B), and catalyst mass percentage (C) using the NiMo/NZA catalyst. The optimization process of the bio-oil production process was carried out using the Response Surface Methodology (RSM) experimental design with a Box-Behnken design. For this purpose, variations in pyrolysis temperature (400; 450; and 500 °C), catalyst metal loading percentage (0; 2; and 4%), and catalyst mass percentage (3; 5; and 7%) were carried out. The pyrolysis reaction was carried out in a pyrolysis reactor as much as 50 grams for 1 hour with the addition of nitrogen gas at a flow rate of 100 ml/minute. The results showed that pyrolysis temperature and metal loading percentage significantly affected the bio-oil yield. The empirical model obtained based on the Box-Behnken design was YBio-oil = 46.91 + 1.45A + 0.6450B + 0.0400C + 0.2550AB - 0.4658A2 - 0.7758B2 - 0.3058C2, which provided an R2 value of 0.9902, indicating that the proposed model was able to explain 99% of the total variance in this experiment. The modeling results indicated that the operating conditions for bio-oil yield obtained at the optimized parameters of pyrolysis temperature of 500°C, catalyst metal loading percentage of 4%, and catalyst mass percentage of 5% were the best settings for the highest bio-oil yield of 48.02%.
