nm)不能进入到分子筛的孔道内(SUZ-4:0.56 nm,ZSM-5:0.56 nm),所以载体孔道外的部分Pt会被二苯并噻吩预处理而失去活性,而孔道内的Pt不会因为预处理仍具有催化活性.实验结果表明,PtSnNa/SUZ-4经过二苯并噻吩预处理后,催化活性大大降低;而PtSnNa/ZSM-5经过二苯并噻吩预处理后,催化活性几乎没有变化.说明PtSnNa/SUZ-4上Pt粒子大部分分散在载体的外表面,从而金属上的积碳不易引起催化剂的失活.","authors":[{"authorName":"周华兰","id":"46b4fdd9-2682-4741-aa2d-234cad9b9aaf","originalAuthorName":"周华兰"},{"authorName":"龚静静","id":"f9df97b3-4232-44a4-a634-7a27f6bfc662","originalAuthorName":"龚静静"},{"authorName":"许波连","id":"983854c9-22ef-4cc7-8acc-d98b8eec8bac","originalAuthorName":"许波连"},{"authorName":"<span
