The product features are: special gear ball shape design, high strength, uniform particle size, ordinary cloth bag filling can achieve dense-phase filling effect, simple and convenient loading and unloading, low abrasion; good dispersion of active components, high class II active phase ratio, high space velocity Low hydrogenation activity is good; it can provide sulfided catalyst, which is directly prepared by using sulfur-containing active metal precursors. Unlike the traditional external presulfurization technology, the catalyst itself is already a highly sulfided finished catalyst, which does not require sulfidation to start work, and is safe and environmentally friendly. The energy-saving and efficiency-increasing effect is remarkable.
