Wood waste can be converted into valuable other materials/bioproducts. Lignocellulosic waste such as wood is essential in functional activated biocarbon raw material. This study aimed to determine the potential of wood waste as raw material for activated biocarbon containing Ni metal as a catalyst. The method started with the carbonization at a temperature of 400°C then activated using 10% H3PQ4 followed by heating at 800°C. The Nickel modification is conducted using the impregnation method. The proximate and acidity product was then analyzed, crystallinity properties using XRD, the functional group using FTIR, morphological properties using SEM, and surface area using SAA. The Ni-biocarbon applicated to the hydrocracking reaction of Cerbera manghas with Hz addition; the ratio of catalyst and feedstock is 1:100 at a temperature of 425°C for 2,5 h reaction time. The product was then analyzed using GCMS. The results showed the moisture, ash, volatile matter, and fixed carbon content were 6.56%, 7.33%, 30.67%, and 62%. The adsorption capacity of the Ni-impregnated biocarbon for iodine, pyridine, and ammonia was 714.41 m2/g, 2.8051 mmol/gram, and 8.8752 mmol/g, respectively. The functional groups on the catalyst's surface consisted of OH, C-H, C-O, and C-C with an irregular and porous surface morphology. The crystallinity and surface area of the Ni-impregnated biocarbon was 52.33% and 870, 662 m2/g, respectively. The hydrocracking product contained alcohol, ketones, ester, carboxylic acid, and aliphatic hydrocarbon. The main desirable compound achieved in this research was the aliphatic hydrocarbon compound of 42% which mainly contained dodecane (27.58%). [ABSTRACT FROM AUTHOR] |
