Ask about some basic knowledge of catalytic cracking catalysts
Thread Content
The recent graded thesis I wrote deals with the control of nitrogen oxides in catalytically regenerated flue gas, and it mentions that basic nitrides in the feedstock are adsorbed onto the acidic sites of the catalyst. But I’m not very familiar with some aspects of catalysts. I’ve seen before that catalysts have structures such as a matrix and active centers, but I’m not entirely clear about the relationships and functions of these various structural elements. I’m worried that questions might be asked on this topic during the defense, so I would appreciate it if experts could explain to me the relevant knowledge about catalytic cracking catalysts. Our factory uses DMMC-2 type catalysts
Catalytic cracking catalysts are basically similar to catalytic reforming catalysts; therefore, it is recommended that you take a look at the second edition of \"Questions and Answers on Catalytic Cracking Technology\", which provides relatively detailed explanations. You can also consider the first edition, as it contains some conceptual information that will also help you understand the relevant topics.
Is it a catalyst for increasing propylene production via heavy oil cracking?
Is your plant a catalytic cracking unit?
Alkaline nitrogen is generally present in relatively high amounts in the coking wax oil, which serves as the raw material for catalysis; this thus limits the proportion of coking wax.
