This study focuses on the use of waste cooking oil (WCO) as the main feedstock for hydrotreatment to evaluate the effect of temperature on the product hydrocarbon composition. A qualitative analysis was initially performed using a GC x GC-TOFMS indicating the presence of mainly paraffins of the C15-C18 range. A quantitative analysis was also performed via a GC-FID, which gave both n-paraffins and iso-paraffins in the range of C8-C29. The results indicate that hydrotreating temperature favors isomerization reactions as the amount of n-paraffins decreases while the amount of iso-paraffins increases. For all experiments the same commercial hydrotreating catalyst was utilized, while the remaining operating parameters were constant (pressure = 1200 psig, LHSV = 1.0 h(-1), H(2)/oil ratio = 4000 scfb, liquid feed = 0.33 ml/min, and gas feed = 0.4 scfh).
