A method for characterizing hydrocracking catalyst acidity by o-xy-

本文报导了用邻二甲苯异构化反应活性表征加氢裂化催化剂及其载体酸性的方法,以邻二甲苯的总转化率表示在反应条件下的反应酸性。用这种方法可将催化剂及载体的反应酸性分成三类:含分子筛或氟的加氢裂化催化剂的反应酸性在55%以上;以无定形硅—铝为载体的加氢裂化催化剂和含氟的无定形硅—铝载体反应酸性大约在10—40%之间;无定形硅—铝载体的反应酸性一般在10%以下。用本方法考察了某些因素对一些加氢裂化催化剂反应酸性的影响。结果表明,硫化型加氢裂化催化剂的反应酸性比氧化型的略低;催化剂上活性金属的含量对反应酸性有明显的影响。

Hydrogenation-dehydrogenation and acidic functions of hydrocracking catalysts were characterized by the use of model compounds of toluene and n-octane in a microreactor. Basic nitrogen compound is added to the toluene feed for the purpose of inhibiting acid catalyzed side reactions during hydrogenation. Pure n-octane was used to examine the hydrocracking activity of amorphous silica-alumina based catalysts at a higher reaction temperature. But for the zeolite based catalysts basic nitrogen compound should be added to the n-octane feed and a lower reaction temperature is required in order to suppress its high cracking activity. This method could be used to differentiate the activities of hydrocracking catalysts.

本文报导了在微型反应器中用模型化合物甲苯及正辛烷表征催化剂的加氢-脱氢及加氢裂解功能的方法。在甲苯中加入碱性氮化物可有效地抑制酸性载体引起的付反应,从而可较真实地表征加氢裂化催化剂的加氢功能。在表征不同类型催化剂的加氢裂解功能时,以无定形硅-铝为载体的催化剂需用较高的反应温度和纯正辛烷为原料;含分子筛催化剂则用较低的反应温度并在正辛烷中加入一定量的碱性氮化物,以便抑制催化剂过高的裂解活性。实验表明,采用建立的表征方法可以较好的区分加氢裂化催化剂的上述反应功能。

The effect of the added phosphorus on the hydrocracking catalysts containing Ni and Mo supported on alumina-zeolite was studied, using UV-Visible Diffuse Reflectance Spectra to determine the spinel NiAl_2O_4,and chromatographic technique to measure the surface acidity. The results show that the added phosphorus inhibits the formation of the spinel NiAl_2O_4 and reduces the acidity of the catalysts. It would be best to add phosphorus in the from of (NH_4)_2HPO_4,NH_4H_2PO_4,and(NH_4)_3PO_4,which....

The effect of the added phosphorus on the hydrocracking catalysts containing Ni and Mo supported on alumina-zeolite was studied, using UV-Visible Diffuse Reflectance Spectra to determine the spinel NiAl_2O_4,and chromatographic technique to measure the surface acidity. The results show that the added phosphorus inhibits the formation of the spinel NiAl_2O_4 and reduces the acidity of the catalysts. It would be best to add phosphorus in the from of (NH_4)_2HPO_4,NH_4H_2PO_4,and(NH_4)_3PO_4,which. can effectively inhibit the formation of spinel and affect the structures of the zeolite less than phosphoric acid. The results also indicate that (NH_4)_2HPO_4, NH_4H_2PO_4, and (NH_4)_3PO_4 have similar inhibition effect. The order of adding phosphorus also affects the formation of the spinel. The appropriate ratio of phosphorus (in the form of H_3P_4) to zeolite for proper acidity of the catalyst has been found to be 0.1.

用紫外——可见漫反射光谱测定NiAl_2O_4尖晶石和用色谱法测定表面酸度考察了加氢裂化催化剂中加磷的作用以及加磷方式的影响。结果表明,加磷抑制了NiAl_2O_4尖晶石的生成,同时使分子筛骨架遭到破坏引起催化剂的酸度降低。以磷酸铵盐形式加磷比以磷酸形式加磷抑制NiAl_2O_4尖晶石生成的效果更好,而且对催化剂中分子筛结构破坏较小,因此是一种较好的加磷方式。不同磷酸铵盐(NH_4)_2HPO_4、NH_4H_2PO_4和(NH_4)_3PO_4对抑制NiAl_2O_4尖晶石生成的效果相近。加磷顺序对NiAl_2O_4尖晶石生成也有影响。由于加氢裂化催化剂的酸度随磷含量增加而降低,为控制催化剂有适量的酸度,应调节超稳Y型分子筛(USY)和磷的加入量,以磷酸形式加磷较适宜的重量比应为P/USY=0.1左右。
