摘要
研究反应温度、反应压力、氢油物质的量比、催化剂装填比例、催化剂再生循环速率等工艺参数对连续重整工艺过程的影响规律。结果表明,随着C5+辛烷值逐渐增加,辛烷值收率出现最大值;当C5+辛烷值达到某一确定值后,再进一步增加C5+辛烷值,C6和C7芳烃收率增加,但C8和C9+芳烃收率略有下降。在此基础上提出"依据目标芳烃产物和辛烷值收率最大化原则进行芳烃型和汽油型装置设计"的理念,兼顾重整生成油的烯烃含量、装置的投资和能耗等,提出新建连续重整装置设计参数的确定原则。
The effect of the operation parameters such as reaction temperature, pressure, space velocity, hydrogen to hydrocarbon mass ratio, catalyst distribution ratio in the reactors and catalyst circulating rate on the CCR process were investigated. The results show that a maximum octane yield （octane barrel） appears with increase of octane number of reformate. When the octane number of reformate is larger than a fixed value, the aromatics yields for C6 and C7 increase but slightly decrease for C8 and C9＋ with increase of octane number of reformate. The design philosophy based on the principle of maximizing octane yield and target aromatics for gasoline-type and aromatics-type CCR units is proposed, respectively. The criteria for determining design parameters for a grass-root CCR unit is made by taking olefin content in reformate, investment of unit and energy consumption into consideration..
