Abstract
The pulping of oil palm fronds with formic acid medium. has been studied
in an effort to develop an efficient and environmentally safe process. This
research is conducted to study the effect of pulping conditions on the pulp yield
and lignin content. The experiment was run at concentration of formic acid in
cooking liquor of 65, 75, 85%-wt, hydrogen peroxide concentration in cooking
liquor of 1, 3" 5%-wt, cooking time of 1, 2, and 3 hours. The cooking of oil palm
fronds was accelerating in a reactor batch at the boiling temperature of formic
acid in standard condition. The effects of dependent variables on the independent
variables were studied by statistical modelling using a second-order incomplete
factorial design. The emprical models were deduced to satisfactorily fit
experimental data with-the values of independent variables and allow quantifiying
the effects of each variables. The most influential factor on yield pulp ·wasformic
acid concentration. Whereas, the cooking time has greater influence on lignin
content.
