| Summary: | Production of BioBTX from Empty Fruit Bunch is becoming an interesting
alternative for chemicals production from biomass. The role of hydrogen source
and catalyst support in BioBTX production were studied in presence of Nickel-
Molybdenum catalyst based using hydrothermal reactor. This study utilize formic
acid in ethanol (FA-EtOH) and Isopropil alcohol (IPA) as hydrogen transfer agent.
Particularly for IPA, the aforementioned substances can be used both as solvent
and reactant (sacrificial alcohol). Two types of catalyst support that were studied
are H-Al-? as Brønsted acid support base and Sn-? as Lewis acid support base. The
role of hydrogen source and catalyst performance were measured by using mass
balance and GC-MS. The catalysts sample were characterized using XRD, H2-TPR
and NH3-TPD.
The experiments were conducted at 300 oC within an hour for each hydrogen source
and catalyst run. The reaction temperature was varied at 225 oC, 255 oC and 300
oC while reaction time was varied from 1 to 2 hour(s).
FA-EtOH system has advantage compared to IPA system which is has lower
selectivity of solvent etherification over both NiMo/H-Al-? and NiMo/Sn-?. On the
catalyst role, NiMo/H- ? is more active compared to NiMo/Sn- ? for both FA-EtOH
and IPA systems. The highest guaiacol conversion was achieved using NiMo/H- ?
in IPA system which is 51,08% and followed by in FA-EtOH system which is
48,66% although IPA system favored C-alkylation of aromatic ring. For that
reason, FA-EtOH system is better than IPA system in term of lignin model
compound conversion and product selectivity. The effect of temperature experiment
using FA-EtOH system shows the declining of guaiacol conversion from 48,66% at
300 oC to 24,64% at 255 oC. Guaiacol reaction doesn’t occur at 225 oC. Toluene
was detected at 255 oC within 2 hour in FA-EtOH using NiMo/H-Al-? catalyst |
