Study on the utilization of palm fruit waste as a pulp raw material organosolv method with hydrothermal pretreatment

Abstract

Palm fronds contain high cellulose, so it can be used as an alternative raw material for making pulp. The purpose of this study is to look at the potential of palm fronds as raw material for making pulp. The process of making pulp used in this study is the organosolv process, which is releasing palm frond fibers with a solution of acetic acid with hydrothermal pretreatment. This study observed the effect of cooking time and cooking solution volume on percent yield. The range of variables used in this study was cooking time of 125,150 and 175 minutes with concentrations of acetic acid cooking solution of 10 percent and 15 percent. The results of pulp quality were analyzed by comparing the results of the cold soda process to obtain physical properties. The best pulp was obtained at 30 minutes cooking time and 175 °C with a tensile value of 0.63 kN / m, tear 228.49 mN and brigthness 13.18.
