SCR CATALYSTS PREPARATION METHODS |
摘要 |
A method of replacing or exchanging non-metal charge balancing cations located at ion-exchanges sites within SAPO frameworks with cations of a transition metal using a solid state ion-exchange process. Transition metal-containing particles are formed on surfaces of SAPO particles, and thereafter the particles are heated in air to initiate the solid-state ion-exchange process. The transition metal-containing particles and the SAPO particles are heated to a temperature and for an amount of time to produce transition metal cations, and for the transition metal cations to replace at least a portion of the non-metal cations located within the SAPO frameworks.
