Abstract
The pulping of oil-palm petioles with formic acid medium has been studied in
an effort to develop an efficient and environmentally safe process. This research was
conducted to study the effects of pulping condition on the pulp yield and lignin
content. Experiment was run at formic acid concentration 65, 75 and 85%-wt,
hydrogen peroxide concentration 1, 3 and 5%-wt and cooking time 1, 2 and 3 hour.
The cooking of oil-pahn petioles was accelerating in reactor bed at boiling
temperature of formic acid in standard condition. The results obtained pulp yield
33.30 - 50.09% with lignin content 11.20 - 19.12% varies depend on cooking
condition. The effect of cooking variable on the pulp yield and hgnin content were
studied by empirical model in second order. The empirical models satisfied to
experimental data with confidence level of 95%.
