- Abstract:
- Using testing methods such as infrared spectrometry and differential heat analysis, the analysis and inspection of the catalysts of the common Y -15FCC catalyst in the catalytic catalytic cracking of petroleum catalytic catalytic cracking are analyzed by the catalyst after the SB passivation agent. The sore catalyst skeleton is measured by the infrared spectrum, and the nickel and cricket basically do not destroy the catalyst. The skeleton and acid center. It can be seen from the DTA diagram. The blank catalyst appears at 200 ° C to 1200 ° C. However, when nickel is deposited, there is a hot peak near 810 ° C, indicating that there is a strong interaction with nickel and molecular sieve at high temperature. It is estimated that NIAL_2O_4 is generated. There are hot peaks of 600 ° C, 680 ° C, etc., indicating that there are common melting materials and NISB_2, Ni_4SB alloy generation, which may be the reason why the pyrotechnic agent has a passional effect on nickel dehydrogenation.
