| Summary: | Benzene, toluene, and xylene (BTX) demand are very high due to their various
application. This high demand is increasing by time. So far, BTX is still produced from
crude oil and fossil resources. However, the declining petroleum oil resources is
threatening the sustainability of BTX production. Therefore, other methods for producing
BTX are important to be studied. Oil palm tree, as one of Indonesia’s largest commodity,
produces waste in the form of empty fruit bunch (EFB). EFB has a high potential to be
used as alternative resources for producing BTX.
The purpose of this research is to develop a catalyst which can be used for conversion of
phenolics compunds derived from lignin depolymerization to produce BTX through a
hydrodeoxygenation process, which is integrated with dehydrogenation of
methylcyclohexane. Methylcyclohexane functions as a hydrogen donor for the
hydrodeoxygenation of phenolic compounds.
There are several stages in this research, including material preparation, catalyst
modification, catalyst characterization, main experiments, and product analysis. The main
ingredients for this research are guaiacol and methylcyclohexane. The catalyst for this
research is Ni-Mo/HBeta. Catalyst activity test is carried out in hydrothermal batch
reactor, at 265oC, 20 bar N2, mass ratio of catalyst to feed 1:10, for 4 hours. Studied
catalysts are HBeta, 3Ni-12Mo/HBeta, 7Ni-8Mo/HBeta, and 12Ni-3Mo/HBeta. Liquid
product is analyzed by using GC-MS.
The data is interpreted by classifying aromatic compounds based on number of oxygen,
methyl, methoxyl, and hydroxyl. The purpose are to find the deoxygenation activity,
methylation, demethoxylation, and dehydroxylation of each catalyst used.
Catalyst which produce toluena from Guaiacol HDO integrated with MCH
dehydrogenation is HBeta. Meanwhile, Ni-Mo/HBeta catalysts are unable to product
BTX due to low dehydroxylation activity, high methylation activity, and decreased
concentration of Brønsted acid sites caused by impregnation. |
