技术领域
本发明涉及一种固体酸载体催化剂的制备方法。
背景技术
固体酸载体催化剂是人类发现的一种新型的催化剂,因酸度高可以活化在通常条件下无活性的饱和烃类,能使饱和烃类发生各种化学反应,更因为克服了液体酸的缺点,具有与反应体系容易分离,不腐蚀设备,环境友好,可以重复使用等优点而受到越来越重视,近年来对固体酸载体催化剂的研究开发也越来广泛,因此需要开发多种不同类型的固体酸载体催化剂来适合不同需要。
发明内容
本发明的目的是提供一种SO4 2-∕ZrO2-WO-AgBr混晶固体酸载体催化剂的制备方法,以克服现有技术存在的上述缺陷。
本发明一种SO4 2-∕ZrO2-WO-AgBr混晶固体酸载体催化剂的制备方法,包括如下步骤:
将氯氧化锆(ZrOCl2)、纳米碳化铬、纳米碳化锆、纳米氧化钨晶须加到水中分散,升温至85-95℃,将溴银溶胶快速加入到混合液中,在持续分散状态下保温2至3小时后降至常温,静置3-6小时,过滤、洗涤沉淀物,干燥去水,然后在450-550℃下焙烧3-4小时;焙烧产物在硫酸中浸渍1至2小时,然后放入650℃~800℃下焙烧3~4小时,得到SO4 2-∕ZrO2-WO-AgBr混晶固体酸载体催化剂。
各组分质量份数如下:水100份、氯氧化锆5-10份、纳米碳化铬0.3-0.6份、纳米碳化锆5-10份、纳米氧化钨晶须10-20份、溴银溶胶30-50份。
所述溴银溶胶可以采用如下方法制备:用25%的氨水20份加入到30份水中,再加入5份硝酸银后发生浑浊,再加2份的硝酸铵使溶液变清,再一次性加入25%的溴化钾水溶液20份,组成溴银溶胶。
所述硫酸的质量浓度优选20~30%;
纳米碳化铬优选粒径50-80纳米;
纳米碳化锆优选粒径20-40纳米;
所述纳米氧化钨晶须直径为0.2-0.3微米、长径比为5-50。例如可采用《微/纳米氧化钨晶须的制备工艺及原理》(《中国有色金属学报》2007年04期,542-546页),公开的方法制备。
本发明是通过溴银溶胶法合成和再结晶掺杂化学反应使氧化物表面掺杂其他载体催化剂,促使氧化物之间形成混合晶体,氧化物表面形成晶格缺陷,扩大比表面积,增加氧化物表面负载酸根离子结合位,显著提高酸的活度,稳定与增加酸中心量,SO4 2-∕ZrO2-WO-AgBr混晶固体酸载体催化剂,重复使用效果好,易于分离,可用于高分子乳液聚合反应,尤其是适用于造纸用高分子类表面施胶剂的制备,能显著提高转化率。
