Application of Y zeolite

Shandong letter Tech as the largest molecular sieve base, specializing in the production of ZSM-5 zeolite, Y-type zeolite , Y zeolite manufacturers today to introduce the application of Y zeolite.
Structure of matter determines the performance, NaY zeolite relatively homogeneous, well-developed pore structure, after the ion exchange retention rich acid catalysis of proton acid sites make it possible. However, due to the high NaO NaY zeolite content, inhibits the normal role of proton acid sites, while NaY zeolite poor thermal stability, and only about 700 ~ C. So inevitably lead directly skeleton collapsed, losing developed a three-dimensional channel, terminate the catalytic reaction to proceed, it is generally reduced through the ion exchange skeleton Na0, ultra-stable process to improve the stability of the skeleton before use.
More ZSM-5 zeolite, Y zeolite information please pay attention to our letter of Shandong Qilu Hua Tech http://www.sdqlhx.com
