Residual Oil Hydrotreating (RHT) Catalyst Series

 

  The residual oil hydrotreating (RHT) catalyst series use alumina or modified alumina as the main feedstock of the carrier, with W, Mo, Ni and Co as active components and assistants. They are suited to removing impurities, such as S, N, metals and remnant carbon from residual oil. RHT catalyst series have good hydrodesulfurization, hydrodenitrogenation, hydrodemetalization and remnant carbon removal abilities, high metal capability, as well as good activity stability, thus can ensure long term stable operation of industrial plants.

Notes: 1. The specifications of the catalyst can be customized as per customers’ requirementsts;

2. Activity appraisal index= HDM ratio of standard catalyst– HDM ratio of the catalyst to be appaised;

3. The catalyst to be appraised is qualified when its HDM ratio (HDM ratio=Ni removing ratio＋V removing ratio) is no less than 3% of the standard HDM ratio.
