The prices of industrial fuels and feedstocks such as naphtha are not capped, yet demand for them is also growing strongly.
工业燃料和石脑油等工业原料的价格并未受到限制，但需求也在强劲增长。

Compared with naphtha, when the yield of ethylene is similar, vegetable oil needs lower reaction temperature, which has important significance for industrial application.
与石脑油相比，在乙烯收率相近时，植物油所需的裂解温度较低，因而具有重要的工业应用价值。

The ratio of C/H is one of the important indexes for evaluation of the naphtha quality in ammonia synthesis. The typical burning-weighted method can not meet the industrial demand of rapid analysis.
