The experiment was carried out with a function of reaction temperature from 420 to 440 â and liquid hourly space velocity (LHSV, 0.3 â 0.5 1/h), hydrogen partial pressure (80-160 bar), H2 to feed ratio (600-2000 Nm3/kl) with molybdenum catalyst concentration of 500 wt.ppm based on metal content on feed in a 4L slurry bubble column reactor. For the analysis of the product yield and properties, gas composition was determined using a gas chromatograph (Agilent 7890) while the liquid properties for the API (D 5002-99), sulfur and metals (nickel and vanadium, D4294-03), micro-carbon residue (MCR, D4530-06), asphaltene (normal heptane insoluble content, D2007), and boiling point distribution (D7500) were all analyzed according to standard ASTM methods. Additional, the amount of sediments and the remained catalyst concentration in the liquid product was examined after reaction.
