The original used Co-Mo prehydrogenation catalyst for hydrotreating straight-run naphtha in the reformer of Chemical Plant in Tianjin Petrochemical Corporation was substituted by Ni-W catalyst, RS-1.

A prehydrogenation catalyst FDS 4A developed by Fushun Research Institute of Petroleum and Petrochemical has been used in the reformer of Anqing General Petrochemical Works for processing high sulfur content feedstock and hydrotreated coker naphtha blended feedstock.

The feed stock is straight run naphtha, with the containing olefins and sulfur contaminants increasing, the developed catalyst for the prehydrogenation process of catalyst reforming, has higher activity and stability.

Preparation of pre-hydrogenation catalyst RS-20 with low price and high space velocity for reforming feedstock

Due to a combination of factors such as the arrangement of hydrogen usage process,pre-hydrogenation booster\'s capacity,feedstock impurities and the existence of iron-bearing substances in the system, the pressure drawdown of the pre-hydrogenation system of the catalytic reforming plant of SINOPEC Jiujiang Company increased loo fast.

Application of LY - 9802 catalyst in reforming gasoline hydrogenation plant;

Investigation on the Causes of Hydrotreating Catalyst Deactivation;

70￣# gasoline,0￣# and-35￣# diesel fuels qualified with the national standards can be produced by pre-saturated hydrogenation,hydrogenation refine and hydroeracking of the feedstock oil.
