1.“Z417/Z418催化劑組合”采用堿性礦物使堿金屬形成穩(wěn)定結(jié)構(gòu)，使用過程中堿金屬釋放緩慢，既保證抗碳需求，又保證催化劑長期使用壽命，并且不對下游造成影響。 2.在裝置設(shè)計條件下達到催化劑的還原活化要求，催化劑鈍化后可以被完成還原。 3.催化劑在氫氣氣氛下活化，條件波動和原料變化造成催化劑積碳和中毒時，可以用蒸汽再生，并且催化劑可以重復(fù)多次再生。 4.西安某石化廠6個月運行周期開停車50余次，催化劑依然滿足使用要求。 5.催化劑適應(yīng)的原料和工藝條件寬,活性穩(wěn)定。 |

1. "Z417/Z418 catalyst composition" takes alkali metal alkaline minerals to form stable structures, alkali metals release slowly in the process of using. It not only ensure against carbon demand, but also ensure long catalyst life, and dosen't affect downstream. 2. In the plant design conditions, it achieve the requirement of reduction of the catalyst activation, catalyst passivation can be done after the restore. 3.The catalyst was activated in hydrogen atmosphere, when catalyst was coked and poisoned caused by changes in volatility and raw materials, It can be regenerated with steam, and the catalyst can be recycled repeatedly. 4.A petrochemical plant in Xi'an parked more than 50 times during 6 months, the catalyst still meets the requirement. 5.Raw materials and process conditions to which Catalyst adapt to was wide,and activity is stable. Keywords: catalyst; alkali metal ;petrochemical plant;Xi'an |

我是個外行，不知翻譯的對不？ 1. "Z417 / Z418 catalyst combination" uses alkaline mineral to form a stable structure. The alkali metal releases slowly in the using process. The requirement of carbon resistance is ensured, and the long-term life of catalyst is also guaranteed. The catalyst has no influence to the downstream (processes). 2. The reduction activation of catalyst is achieved under the designing conditions of the device, and the passivated catalyst can be completely reduced. 3. The catalyst is activated under an atmosphere of hydrogen. Fluctuation of conditions and the changes of raw material may cause carbon deposition and poisoning of catalyst, but the activity of catalyst can be regenerated again and again by using steam. 4. In a (pilot) petrochemical enterprise of Xi’an, the catalyst can still meet the using requirement during an operation cycle of 6 months with more than 50 times of start-up/stop-down processes. 5. The activity of the catalyst is stable, and it can be widely adapted to many raw materials and process conditions. |
