Abstract:
Recently, for its direct use as a renewable energy resource of pyrolysis biomass, liquid smoke has received increased attention. Unfornatunately, the composition of liquid smoke is very complex that cause to obvious changes in chemical properties of the liquid smoke. Therefore, the hydrodeoxygenation method required to handle this issue. The Objective of this research was the hydrodeoxygenation of liquid smoke to remove oxygenated compounds with decreased concentration of ketones and increased phenol concentration using sarulla natural zeolite dialuminated with 3M, 5M and 7M HCl concentrations at 90°C in the H2 atmosphere. Characterization of hydrodeoxygenation product was analyzed content by gas chromatography-mass spectrometry (GC-MS). The results showed a decrease in phenol content and a rise in carbonyl at 7 M HCl dealumination while 5 M HCl dealumination increased phenol content and reduced carbonyl compounds. Treatment with concentration of 5 M HCl results in a better content o
f liquid smoke.
