适用于裂解制造乙烯的气体动力学加热方法

对乙烷裂解制造乙烯的非平均过程进行了分析，为了获得高的乙烯产率，需准确控制裂解停留时间并提高裂解反应温度，探讨了目前工业生产中普遍采用的管式裂解炉的特性及局限，这种管式裂解炉的性能虽已接近完善，但仍不能满足裂解工艺需求，对几种利用激波控制加热方式生产乙烯的发明及其不足进行了评述，提出新颖的反向超声速射流混合加热方法，该方法能满足裂解制造乙烯的要求。

Gasdynamic heating process suitable for manufacturing ethene by pyrolysis

Nonequilibrium process for cracking ethane in the manufacture of ethene is numerically investigated. Higher ethene yield will be obtained by controlling the resident time of pyrolysis and by increasing the temperature of pyrolysis reaction. The characteristics and the limitations of vertical pipe furnaces in common use in industry are surveyed. Although their performance has approached perfection, it can not meet the requirements of pyrolysis technology. Several inventions by means of shock wave controlled reactor for manufaturing ethene and their inadequacy are evaluated. The heating process by opposite mixing of supersonic jets which is satisfactory to optimum conditions of cracking technology is proposed.
