重油制取低碳烯烃工艺氢分配规律的探讨

Study on Rules of Hydrogen Distribution in the Process of Producing Low Molecular Olefins from Heavy Oil

在中国制取低碳烯烃的原料中，重质馏份油占有相当比重。通过对加氢裂化及其尾油的蒸汽裂解工艺的氢平衡计算及氢分配规律的探讨，证明ＨＣ（ＭＨＣ）－ＳＣＲ工艺的氢分配比较合理，得到了较好的利用。

Heavy distillates make up a large fraction of feedstock for producing low molecular olefins in China.By calculating hydrogen balance and studying the rule of hydrogen distribution in hydrocracking and steam cracking of the resulting tail oil,it can be proved that the hydrogen in the process of HC(MHC) SCR is reasonably distributed and well utilized.
