| titleOfInvention | Preparation method and application of high-silicon Cu-LTA catalyst |
| abstract | The invention provides a preparation method of a Cu-LTA catalyst, which adopts a double template agent one-step method to synthesize the Cu-LTA catalyst, the copper loading capacity is regulated to be 1.00-5.00 wt% by controlling the feeding proportion of the copper sulfate-tetraethylenepentamine and the organic template agent, simultaneously controlling the feeding ratio of the aluminum source and the silicon source to regulate the silicon-aluminum ratio to be 4-20 to obtain the Cu-LTA molecular sieve catalyst with excellent catalytic activity and hydrothermal stability, the method can introduce Cu species into the LTA molecular sieve structure in situ, can control the introduction amount of the Cu species, overcomes the defect that the traditional synthesis method needs to load active components through a later-stage ion exchange process, avoids the ion exchange and separation of ammonium nitrate and copper salt solution which are used for multiple times, saves energy, is environment-friendly, and the prepared Cu-LTA catalyst keeps excellent NH in a wider temperature window. 3 SCR catalytic activity and simultaneously has excellent hydrothermal stability. |
