Hydrocracking of polypropylene using iron on activated carbon from palm oil shell

Abstract

The main objective of this research was aimed to study the conversion of polypropylene into oil product using iron on activated carbon catalyst in a microreactor, width of 30 mm inside diameter and innervolume of 75 ml, by varying operation conditions as pressure of hydrogen gas range of 28 to 50 kg/cm2 reaction temperature between 395 and 455 ํC and reaction time 30 to 90 min for each catalyst. From the results, it was found that reaction temperature of 435 ํC was the temperature that yielded the highest quantity of oil product. This temperature was also used in studying the effect of pressure for hydrogen gas, reaction time and ratio of polypropylene to iron on activated carbon catalyst. The analyzed oil product from gas chromatography (GC Simulated Distillation) was found that iron on activated carbon was suitable and used as catalyst at 435 ํC, hydrogen pressure at 30 kg/cm2 and reaction time 60 min the product yield was in the range of 40-65% naphtha, 12-14% kerosene, 10-13% gas oil and 4-5% long residues.
