摘要:
利用红外光谱法、差热分析等测试手段,对石油催化裂解中的共Y—15FCC催化剂在镍沉积前后,及再经Sb钝化剂处理后的催化剂分别进行了分析考察.由红外光谱对催化剂骨架测定,及用吡啶作探针的酸中心测定,发现镍、锑基本上不破坏催化剂的骨架及酸中心.由DTA图可看到,空白催化剂在200℃～1200℃无任何吸热或放热峰出现.但当镍沉积后,在810℃附近有一放热峰,说明在高温下镍与分子筛有较强的相互作用,估计有NiAl_2O_4生成.当催化剂上有镍及锑沈积后,在530℃、600℃、680℃等处有吸热峰,说明有共熔物及N
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.
