普通液态烃非临氢ＦＣＣ工艺，进料为沸点大于３４３的烃，在裂化反应器中与再生平衡催化剂接触，催化剂为２０～１００ｍ细粒，催化活性组分ＭＣＭ－４９。与以往工艺相比，在满足希望的烯烃产品产率的情况下，可改进产品性能。该工艺不需对现有装置做太大的改造。FCC工艺──
Normal liquid hydrocarbon non-hydrogen FCC process, the feed is a hydrocarbon having a boiling point of more than 343 and is contacted with a regeneration balance catalyst in a cracking reactor, wherein the catalyst is 20-100m fine particles and the catalytically active component MCM-49. Compared with the prior art, product performance can be improved while meeting the desired olefin product yield. The process does not require much modification of existing equipment. FCC process ─ ─
