residue condition

Comparison tests were made between RU small riser catalyst test apparatus and commercial residue fluid catalytic cracking ( RFCC) unit under the same reaction and regeneration condition. The results showed that a strong correlation between both of them.

通过不同阶段随机抽样实验比较，使用工业重油催化裂化（RFCC）装置进料和催化剂（平衡剂），采用相同的反应和再生条件，在RU小型提升管催化剂评价装置上做比较实验。

In constituted condition of lixiviation and washing the lixiviated residue using washing solution with fixed concentration, the lixiviating rate of Au and Pd reached 98% from the catalyst and the direct recovery rate was more than 97%.

在拟定的浸出条件下和使用一定浓度的浸洗剂清洗浸出渣，使催化剂中金钯浸出率98%，金属直收率97%。
