Description

Co(10)/Hβ(600)催化剂的制备方法
技术领域
本发明涉及一种Co(10)/Hβ(600)催化剂的制备方法。
背景技术
N2O不仅破坏大气中的臭氧层,而且还是导致全球变暖的重要温室气体之一,是全世界不容忽视的大气污染物。N2O温室效应仅次于CO2和CH4,位列第三大温室气体,其全球增暖潜能GWP(globalwarningpotential)是CO2的310倍,在对流层停留时间长达120年,N2O以每年0.2%～0.3%的速率增加,N2O的大气浓度每增加1倍将导致全球升温0.3℃。改善大气环境,控制N2O排放,是当今环保领域亟需解决的重点和难点问题之一。N2O的排放源主要包括己二酸和硝酸的生产,矿物燃料的燃烧和机动车尾气的排放。催化分解法将N2O分解为无毒无害的N2和O2,是消除N2O的有效方法。钴基尖晶石氧化物在N2O分解中表现出优良的性能,但其比表面积小,活性组分利用率低,不利于工业应用。分子筛是一类结晶的硅铝酸盐,有均一规整的孔道和极大的比表面积,具有热稳定性好、内表面积大、强度高等特点。如果将具有尖晶石结构的钴物种负载在具有较大比表面积的分子筛载体上使其高度分散,可降低催化剂活性组分用量,降低催化剂成本,有利于工业应用,同时活性组分与载体的协同作用可能有利于改善催化剂的催化性能。
发明内容
本发明旨在提出一种用于分解N2O的负载钴物种催化剂。
本发明所述一种Co(10)/Hβ(600)催化剂的制备方法，包括以下步骤：（1）称取适量的硝酸钴溶解于去离子水中,并加入适量的Hβ分子筛载体；(2)在40℃下搅拌4h,静置过夜,蒸干水分得到催化剂前躯体产物；（3）催化剂前躯体产物于600℃焙烧4h,得到Hβ分子筛负载钴氧化物催化剂；（4）以分子筛载体质量为基准,Co的质量分数为10%,600℃的温度下焙烧，焙烧后的产物为Co(10)/Hβ(600)。
本发明所述的催化剂具有规则孔道和大比表面积,可工业化生产，实用性强。
具体实施方式
本发明所述一种Co(10)/Hβ(600)催化剂的制备方法，包括以下步骤：（1）称取适量的硝酸钴溶解于去离子水中,并加入适量的Hβ分子筛载体；(2)在40℃下搅拌4h,静置过夜,蒸干水分得到催化剂前躯体产物；（3）催化剂前躯体产物于600℃焙烧4h,得到Hβ分子筛负载钴氧化物催化剂；（4）以分子筛载体质量为基准,Co的质量分数为10%,600℃的温度下焙烧，焙烧后的产物为Co(10)/Hβ(600)。
