Abstract
A series of gas-oil hydro treating experiments were carried out under different operating conditions; reaction temperatures 300-425°C, hydrogen pressures 15- 65 bar, liquid hourly space velocities 0.5-1.50 h-1, while H2/feed ratio and time of products collection was kept constant at 250 L/L and 9 hours respectively. A commercially CoO MoO3 / Al2O3 - hydro treated catalyst was used in the catalytic activity tests. The runs were conducted in a fixed bed-cata test unit. HDS of HVGO was improved at reaction temperature 400°C which reached (98.88), at pressure 50 reached (79.92) and at LHSV 0.5 reached (83.26). Main characteristics and the product quality as diesel index (DI), color and pour point was improved but the total aromatics content was decreased with the reaction temperature, pressure increase and increase with decrease LHSV.
