Several parameters influence the efficiency of the HDS process:
Temperature: Higher temperatures generally increase reaction rates but may also lead to undesirable side reactions. Pressure: Elevated pressures enhance hydrogen solubility and improve contact between the hydrogen and the feedstock. Hydrogen-to-Hydrocarbon Ratio: A higher ratio ensures more hydrogen is available to react with sulfur compounds. Space Velocity: Lower space velocities allow more contact time between the feedstock and the catalyst, improving desulfurization efficiency.
