摘要
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（ＴＩＰＳ）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．
Coking behavior of naphthalene oligomerization over SO 2- 4/ZrO 2 solid superacid was studied in detail. The results indicated that this kind of coking reaction was a self deactivated catalytical reaction and the coke was produced largely in the early stage of reaction and then increased slowly. Most of the coke was soluble in pyridine (≈90%). The coke could be easily removed by oxidation at low temperature. The pyrolysis product of the coke exhibited excellent anisotropic texture.
