          HBW-1/2 crude benzene hydrogenation catalyst

          Release time:2017-04-11 09:38:11    source:

          HBW crude benzene hydrotreating catalyst, with a large pore volume, specific surface area, the appearance of clover-shaped, with excellent compression, wear strength.
          HBW-1 pre-hydrogenation catalyst is a W-Ni-Mo / Al2O3 catalyst with good performance of low temperature hydrogenated saturated diene and alkenyl aromatics. In order to prolong the operation cycle of the device, a large amount of highly unsaturated hydrocarbons Polymerization results in the top of the reactor coking, usually using a reverse oil circulation process to dilute the diene and alkenyl aromatic content, while taking a lot of reaction heat, control the reaction temperature rise, improve the selectivity of a hydrogenation. At the same time, in the first paragraph of the top of the bed filled with a certain amount of hydrogenation protection agent.
          HB-2 is a two-stage reactor HDS catalyst, Co-Mo / Al2O3 catalyst low temperature desulfurization and denitrification performance, the catalyst on the C-S, C-N, C-O bond fracture has a high activity, but the C-C bond fracture weak. Therefore, the use of CO-MO catalyst with high liquid yield, low hydrogen consumption, the advantages of slow coking.
          At the same time, the HBW-2 catalyst has a large specific surface area and pore volume, and the microporous design of the carrier can accommodate the coke produced during the hydrogenation process.
