摘要
催化重整(简称重整)原料的组成对重整反应产生了多方面的影响。分析了连续重整原料中烷烃、环烷烃、芳烃等组成特性和现状差异,以及各类烃在重整反应中转化率的变化及其对主要产品的影响。基于此,提出优化重石脑油组成、降低原料中C_(6)和C_(11)+含量、控制轻石脑油和重石脑油产品质量等优化建议。通过模拟测算,优化重整混合原料,降低原料中无效组分含量,消除装置运行瓶颈,为同类装置原料优化提供了数据支撑,助力炼化企业提质增效与低碳转型。
The differential distribution of reforming raw materials has multiple impacts on the reforming reaction.This paper thoroughly analyzes the compositional characteristics and current-situation differences of alkanes,naphthenes,aromatics,etc.in the CCR feedstock,as well as the changes in the conversion rates of various hydrocarbons in the reforming reaction and their impacts on the main products.Based on this,optimization suggestions such as cutting heavy naphtha,reducing the contents of C_(6) and C_(11)+,and controlling the product quality of light naphtha and heavy naphtha are put forward.Through simulation calculation,by optimizing the reforming mixed feedstock,reducing the ineffective components in the feedstock,and eliminating the operation bottleneck of the unit,it provides data support and engineering reference for the feedstock optimization of similar units,helping refining and chemical enterprises to improve quality and efficiency and achieve low-carbon transformation.
