Liquefaction process of wholestalk kenaf wood at different phenol-kenaf ratio

Wholestalk Kenaf were liquefied using phenol as liquefaction medium, while sulfuric acid was used as liquefaction catalyst. Kenaf liquefaction process was performed in a glass flask equipped with thermometer, condenser systems and mechanical stirrer. The efficiency of the liquefaction process depended on the raw materials and parameter used. Liquefaction of kenaf were carried out with different phenol/kenaf ratios at 150 °C using 3% of sulfuric acid. Characterization was carried out on liquefaction kenaf residues to study their morphology properties. Liquefaction data showed that the liquefaction residue with parameter percent of sulfuric acid 4 %, F/K ratio 2.5/1.0, 90 minutes and 170 °C gave optimum conversion percentage as high as 89.04% of liquefied kenaf.
