LaNi〓 can be easily activated at room temperature and activated LaNi〓 possesses catalysing effect for the dissociation of H〓, which greatly reduces the energy barrier for dissociation of H〓. Hydrogen passed through LaNi〓 particles, then diffused into the crystal lattices of V、Nb and TiFe alloy and formed hydrogenate.

It was found that low hydrogen purity and high moisture content of the hydrogen used for deoxidation was the main cause. Countermeasures such as exhausting 90% of the waste gas from the deoxidation process to hydrogen recompression system to reduce the water content in deoxidation zone, and using hydrogen from PSA unit to replace recycle hydrogen to increase the hydrogen purity, were adopted.

参考UOP公司及其它重整装置的经验，对重整催化剂还原工艺进行了改进，将90％的还原废气排入增压氢系统，可有效降低还原区的水含量；用PSA氢替代循环氢，可进一步提高还原区氢纯度，从而提高还原反应速度，改善再生催化剂的性能，使重整反应的芳烃产率有所提高。

The substance which gives up hydrogen is said to be oxidized and the one which accepts the hydrogen is sais to be reduced.

释出氢的物质是氧化物，吸收氢的物质减少了。如果化学学的认真点就不是这样了。一个物质失去氢叫做被氧化，一个物质得到氢叫做被还原。
