Carbonizing aluminum oxide gel
1.Chemical formula:Al₂O₃·nH₂O
2.Properties and uses:
This product is a pseudo boehmite(i.e.aluminum binder)produced by continuous carbonization.the continuous carbonization method is exclusively produced domestically,with advanced production technology,pure crystal phase,low impurity content,and gamma type alumina generated after heat treatment.It has good thermal stability and is an ideal raw material for producing high-quality catalysts and catalyst carriers.Mainly used as raw materials for catalysts,catalyst carriers,adsorbents,and binders,such as silver catalyst carriers,toluene disproportionation catalyst carriers,pour point depressants,hydrogenation refining catalyst carriers,etc;Used as a binder for semi synthetic processes of petroleum cracking catalysts,it can replace imported SB aluminum glue;It can also be used as a surface coating for catalyst carriers,in the flocking industry,etc.The silver catalyst made from WHA-404 as a carrier has reached the international advanced level.
