Studies on Hydrotreating Process of Microcrystalline Wax Pro

Abstract
Microcrystalline wax was produced from solvent dewaxing process of vacuum
residue raffinate produced from Marine Belayim origin .
The untreated microcrystalline wax contains trace amounts of sufur, oxygen,
nitrogen and organomettalic compounds as well as heavy aromatics which affect the
properties of wax applications in pharmaceutical and technical fields .
Microcrystalline wax hydrotreating process was studied using digital controlled
unit and NiO-MOO3 / AL2O3 catalyst, where operating parameters that controlled
the efficiency of the hydrotreated wax were studied separately at different values
including reactor temperature, reactor pressure, liquid hourly space velocity and
hydrogen to hydrocarbon ratio .
Hydrotreated microcrystalline wax at operating conditions (temperature 300 °C,
pressure 73 kg/cm2, LHS V 0.52 h-1 and H2/HC ratio 266.6 Nm3/m3) has the best
quality to be used as food grade wax .
