Abstract
Nowadays, energy and environmental issues become more intense and prevalent to be discussed in most occasions. Uncontrolled utility of fossil fuel without any awareness to environmental impacts, certainly endangers our modern civilization. Lignocellulosicderived biomass is claimed by scientists as green-based-energy alternative to replace the fossil fuel soon or later. Further processes need to be performed to make chemicals-derived-lignocellulosic ready to be utilized, and hydrogenation is one of them. Tetrahydrofurfuryl alcohol (THFA) is one of hydrogenation’s products originated from furfuryl alcohol (FFA) which has been regarded as ―green‖ solvent in agriculture sector and precursor for another useful chemicals. Hydrogenation usually is performed under high pressure (above 10 bar) and above 100°C. Author initiated to carry on liquid-phase hydrogenation under open system and 30˚C using NaBH4 as hydrogen-generator. Gasphase hydrogenation had also been performed under certain condition, and its optimum results were used to compare to previous optimum results. Commercial catalyst rhodium embedded on carbon was chosen to carry hydrogenation. System using NaBH4 could achieve 100% conversion of FFA and 79% yield towards THFA at 30˚C for 2 hours reaction. System using H2 gas could convert 94% of FFA and 93% yield towards THFA at 50°C for 11 hours reaction. Despite of selectivity factor, NaBH4 system still achieved high yield, and not forget to mention room temperature reaction, and simple apparatus preparation became value-added. Hydrogenation using NaBH4 could become one option to be considered.
