用于通过裂化形成轻质烯烃的方法
摘要：
根据当前公开的一个或多个实施例，轻质烯烃可以通过一种可以包括以下之方法形成：将进料流引入到反应器中；使所述进料流与裂化催化剂在所述反应器中反应以形成产物流；以及处理所述裂化催化剂。所述反应器可以包括上游反应器区段和下游反应器区段。所述上游反应器区段可以定位在所述下游反应器区段的下方。所述上游反应器区段的平均横截面面积可以是所述下游反应器区段的平均横截面面积的至少150％。
摘要（英）：

According to one or more embodiments presently disclosed, light olefins may be formed by a method that may comprise introducing a feed stream into a reactor, reacting the feed stream with a cracking catalyst in the reactor to form a product stream, and processing the cracking catalyst. The reactor may comprise an upstream reactor section and a downstream reactor section. The upstream reactor section may be positioned below the downstream reactor section. The upstream reactor section may have an average cross-sectional area that is at least 150% of the average cross-sectional area of the downstream reactor section.
