可基本避免在蒸汽裂解装置炉管内表面发生炭沉积的涂层技术将由美国Quantiam技术公司推向商业化应用。在5台乙烯裂解炉上进行的商业化规模试验结果表明,对于轻质原料,使用涂层后可使裂解炉清焦时间延长至1～2年,而未涂层的炉管约每30天就必须 Coating technology that substantially avoids carbon deposition on the inner surface of steam cracker tubes will be commercialized by Quantiam Technologies of the United States. The results of a commercial scale test conducted on five ethylene cracking furnaces show that for light materials, the use of the coating prolongs the period of defocusing of the cracker to one to two years, whereas the uncoated furnace tube takes approximately 30 days It must
