Pirolisis Lignin Dari Limbah Industri Kelapa Sawit Untuk Pengembangan Surfaktan Dalam Proses Enhance Oil Recovery (Eor) (Pyrolysis of Lignin From Waste of Palm Oil Industries for the Development of Surfactants for Enhance Oil Recovery (Eor))

Pyrolysis of lignin from waste of palm oil industries produces alcohol and its derivatives which can be sulfonated to become surfactant. The experimental procedures for the pyrolysis process were as follows: 1) dried palm oil husks at a certain weight were put into the pyrolysis reactor and heated up to a certain temperafure; 2) the product leaving the reactor was cooled down to room temperature; and 3) the liquid product was collected in a flask while the gas product was put into a big bottle. The best temperature obtained for producing liquid product was 400 oC for lignin from palm oil fruit fibers and 350 oC for lignin from palm oil fruit stems. The surfactant developed was in the range between 34 and 38% from the pyrolysis product. In this experiment, the reaction rate was assumed to be in first order. The result showed that the surfactant obtained from the experiment could form emulsion with crude oil. This suggests that the surfactant developed can be used for EOR process
