Abstract:
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).

Metals like palladium, platinum, and nickel are commonly used in their solid forms — fine powder on an inert surface. As these catalysts remain insoluble in the reaction mixture, they are referred to as heterogeneous catalysts.
