BMCI的音标

In the situation of gaining the same quality unconverted oil ( the BMCI value was about 10), the yield of unconverted oil when using new catalysts would be about 15% higher than that of RMC technology.

而在尾油质量相当（BMCI值为10）的条件下，尾油收率较原催化剂增加约15个百分点。

About 19~-27 wt% of ethylene yield can be obtained from various heavy feedstocks ( BMCI values between 20 to 50) in riser pilot plant at typical operating conditions.

在典型的工艺条件下，不同的重质原料油（BMCI值为20～50）在中型提升管装置上，其乙烯产率可达19w%～27w%。

Applying the method of mathematical statistics, the model for predicting olefin yield distribution of hydrocarbon cracking is obtained. There are three parameters in the model, which are BMCI, cracking temperature and residence time.

采用经验法，以芳烃指数、裂解温度、停留时间为参数，建立烃类裂解烯烃产率分布模型。
