仔细研究了萘在ＳＯ２－４／ＺｒＯ２固体超强酸催化剂上进行齐聚反应时的结焦规律．结果表明，这种结焦反应是一种自失活的催化反应，反应初期焦已大量生成，随后焦的生成量平缓增加．这种焦主要以甲苯不溶吡啶可溶（ＴＩＰＳ）组分为主，含有较少量的吡啶不溶（ＰＩ）组分．烧焦反应结果表明，这是一种轻焦，易被氧化除去．焦的热解产物表现出较好的偏光显微形态． The coke formation behavior of naphthalene during oligomerization of SO2-4 / ZrO2 solid superacid catalyst was carefully studied. The results show that this coking reaction is a self-deactivating catalytic reaction, the initial reaction has been a large number of coke production, followed by coke production increased gently. This coke is mainly dominated by toluene insoluble pyridine soluble (TIPS) components, containing a smaller amount of pyridine insoluble (PI) components. Charred reaction results show that this is a light coke, easily oxidized to remove. Coke pyrolysis products showed better polarization microstructure.
