Characters
HYS-04 is a hydrodemetal catalyst, taking Ni and Mo as active component and modifiedα-Al2O3 as support. Its comprehensive performances stand at the international advanced level.
■ Excellent mechanical strength.
■ Large pore.
■ Excellent hydrodemetal activities, especially for iron ion.
■ Excellent carbonization resistance.
■ Excellent activity stability, suitable for feedstock and
■ Effectively preventing downstream hydrotreating catalysts extending unit operation cycle.
Applications and operating conditions
HYLH-04 is suitable for various hydrogenation units, partly or completely replacing ceramic balls and porous filler loaded on the upper of catalyst beds, removing and depositing metal ions especially iron in their own passageways, avoiding the hydrotreating catalyst coked and hardened, inhibiting the rise of pressure drop extending unit operation cycle.
■Operating Temperatures: 230~400℃
■Pressures: 1.0~18.0MPa
■ H2 / oil ratio: 100~1200
