针对热等离子体裂解催化裂化油浆体系中淬冷过程的关键影响因素,介绍了耦合C1～C3烃类详细气相动力学和炭黑生成机理的University of Southern California(USC)扩展动力学,并对乙烷淬冷方案进行模拟,与在实验装置上进行的乙烷淬冷实验结果对照良好,表明USC扩展机理适用于该体系的动力学模拟。系统分析了淬冷过程中淬冷后温度、淬冷速率、淬冷氛围等关键因素对乙炔分解的影响,结果表明淬冷后温度控制在800 K,淬冷速率控制在1.2×105 K·s-1以上可以保证乙炔的损失率在可接受的范围内,同时氢气的存在可以减少乙炔损失,从而为淬冷过程的调控提供了明确的指导。
Abstract：The extended USC kinetics of detailed gas-phase kinetics of C1-C3 hydrocarbons and mechanism of carbon black formation were introduced for key factor analysis of quenching process in pyrolysis of catalytic slurry oil via plasma.The simulation of ethane quenching was conducted and showed good agreement compared with experimental results.Then the effects of key factors such as after-quench temperature,quenching rate and atmosphere of quenching in quenching process were analyzed systematically.The results show that when after-quench temperature and quenching cooling rate were controlled at above 800 K and 1.2×105 K·s-1 respectively,the loss rate of acetylene could be guaranteed to be within an acceptable range.Besides,the existence of hydrogen could reduce the loss of acetylene.The results provide reference for process control of quenching.
