Ⅵ.New Catalyst Materials

• ADVANCE IN NOVEL CATALYTICAL MATERIALS

  Ling Fengxiang Tong Guangming　　　　

  Abstract 　Catalysts play a key role in techniques of oil refining and petrochemicals production. Any new catalyst or new technology is always based on the development of novel catalytical materials. The purpose of this paper is mainly to summarize the recent research status and the advance in novel catalytical materials both at home country and abroad, such as new structural zeolites, heteroatomic zeolites (Ti-Si zeolite and aluminophosphate-zeolite), novel catalytical materials of b -zeolite, new chemical modification methods for Y-zeolite, pillared-layer clay zeolite, MoN, BN, nanosized materials and so on..

  　

• STUDY ON PHYSICO-CHEMICAL CHARACTERISTIC OF HIGH NITROGEN TOLERANT Y ZEOLITE

  Yin Zequn　　　　

  Abstract 　Two types of commercially improved Y zeolites (NTY and USY) are characterized by XRD, IR, NMR, NH4-TPD, low-temperature nitrogen adsorption and high pressure micro-reactor. It was found that the high nitrogen tolerant Y zeolite (NTY), prepared by hydrothermo-treating NH₄Y zeolite followed by acid treating, showed improved tolerance to nitrogen and ring-opening ability, compared with USY (ultrastable Y zeolite).

  　

• SUPPORT, METAL-SUPPORT INTERACTION AND PREPARATION OF HETEROGENEOUS CATALYSTS

  Luo Xihui　　　　

  Abstract 　This contribution is an attempt to give an overview in preparing heterogeneous catalysts particularly associating Mo(W)Ni(Co)/Al₂O₃ hydrotreating catalysts and PtRe/Al₂O₃ reforming catalysts. The discussion is centered on studying support, metal-support interaction and its effect on the nature of surface phase (phases), or surface morphology of support and the related catalysts on the atomic scale. In conjunction with TPR, DRS, ESCA, IR, and micro-reactor, a new surface technique, a new surface technique, PASCA (Positron annihilation spectroscopy for chemical analysis) was used to characterize these two kinds of supports and the related catalysts. Based on these results, ideas for developing new hydrotreating and catalytic reforming catalysts are proposed.

  Abstract 　This article describes the R&D of g-Al₂O₃ as support of CB-8 series of catalytic reforming catalysts. The reason for good serviceability of this new type of carrier is also discussed.

  　

• APPLICATION OF MOLECULE SIMULATION IN STUDY OF CATALYTIC MATERIAL

  Lan Quan Li Yuansheng　　　　

  Abstract 　This paper gives a brief review on establishing laboratory of molecule simulation and the research progress. The discussion is centered on the application of molecule simulation in the study of catalytic materials. The molecule simulation system has used to some auxiliary study on the molecular sieves, and to successfully analyze the structure of some synthesized products. It has been used to study the support material of hydrofining catalysts, and to investigate the adsorption of various molecular sieves on model sulfur-containing compounds.
