[求助] 请帮助汉译成英语,谢谢

1.“Z417/Z418催化剂组合”采用碱性矿物使碱金属形成稳定结构,使用过程中碱金属释放缓慢,既保证抗碳需求,又保证催化剂长期使用寿命,并且不对下游造成影响。

2.在装置设计条件下达到催化剂的还原活化要求,催化剂钝化后可以被完成还原。

3.催化剂在氢气气氛下活化,条件波动和原料变化造成催化剂积碳和中毒时,可以用蒸汽再生,并且催化剂可以重复多次再生。

4.西安某石化厂6个月运行周期开停车50余次,催化剂依然满足使用要求。

5.催化剂适应的原料和工艺条件宽,活性稳定。

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

我是个外行,不知翻译的对不?

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.
