Пожалуйста, объясните,为什么催化剂含碳量低于3%时,为什么再生系统会不稳?为什么含碳量在4-6之间在烧焦?

В соответствии с этим стандартом было проектировано,原设计按此标准设计,低于此标准当然会出问题

Если содержание углерода низкое,如果含碳量较低,那床温就起不来,一旦起不来,催化剂活性就会有问题,所以只能把含碳提高后再烧,这个也是蜡油裂化的一个特点不过现有的设计的参数应该是根据原料性质来的所以不会出现这种情况按照设计参数调整就Ok

4楼楼解,碳含量过低烧焦热太少,床层温度不够烧焦速度保证不了、炭烧不掉、另外配风量太少氧含量很难控制、很容易超高热停车。

Я не совсем понимаю、为什么温度起不来、会造成催化剂活性影响?如果要是低碳量、不是也可以注氧烧焦吗

焦的多少、产生的热量不一样、导致催化剂的活性不一样

6楼楼解、催化剂含碳低的时候产生的烧焦温升很小、同样的烧焦入口温度时烧焦床层温度很低、烧焦效果不好、而且耗氧量太少、床层氧含量不容易控制、如果烧焦床氧含量过高时还易造成超温。
