Cracking of polybutene-1 to liquid fuels on Fe/Activated carbon catalyst

Abstract

The main objective of this research was aimed to study the cracking of polybutene-1 to liquid fuels on Fe/Activated carbon catalyst in a microreactor, of 30 mm inside diameter and inner volume of 70 ml, by varying operation conditions as reaction temperature between 385-425 ℃, initial hydrogen pressure range of 20-40 kg/cm² and reaction time 30-90 min. From the experiment results, It was found that reaction temperature of 410 ℃ was the temperature yielded the highest oil product. This temperature was also used in studying the effect of initial hydrogen pressure, reaction time and catalyst amount. The analyzed oil product from gas chromatography (GC Simulated Distillation) was found that Fe/Activated carbon was suitable and used as catalyst at 410 ℃, initial hydrogen pressure at 40 kg/cm² and reaction time 60 min 5% Fe/Activated carbon. It produced 6.86% gas yield, 88.57% oil yield and 4.57% solid yield. The oil product consists of 45.76% naphtha, 13.77% kerosene, 9.59% light gas oil, 6.89% heavy gas oil and 12.56% long residues.
