摘要

SAPO-34 zeolites with uniform mesopores have been successfully synthesized using polyethyleneimine (PEI) dendrimer as co-template through conventional hydrothermal synthesis for microporous crystalline SAPO-34. This series of SAPO-34 possesses higher BET specific surface area (as high as 560 m(2) g(-1)) and larger mesoporous volume (as large as 0.27 cm(3) g(-1)). The size and volume for the mesopores can be adjusted by the molecular weight and the amount of the PEI added. The hierarchical SAPO-34 would be a potential industrial catalyst for methanol-to-olefin (MTO) and methanol-to-propylene (MTP) conversions.

The hydrothermal synthesis of hierarchical SAPO-34 with improved MTO performance

Peixin Rui, Baorong Wang, Feibiao Chen, Yanjuan Xiang, Jianming Yang, Tao Guo, Zheng Wu, Weilin Liao, Xingtian Shu

Summary: The fabrication of intracrystalline secondary pores is crucial for enhancing the catalytic performance of microporous zeolites. A two-step crystallization process using AlPO4 was found to be effective in synthesizing hierarchical SAPO-34 with abundant intracrystalline secondary porosity in a short period of time, leading to improved MTO activity and selectivity.

Effects of Synthesis Variables on SAPO-34 Crystallization Templated Using Pyridinium Supramolecule and Its Catalytic Activity in Microwave Esterification Synthesis of Propyl Levulinate

Yik-Ken Ma, Taghrid S. S. Alomar, Najla AlMasoud, Zeinhom M. M. El-Bahy, Stephen Chia, T. Jean Daou, Fitri Khoerunnisa, Tau Chuan Ling, Eng-Poh Ng

Summary: A detailed study on the hydrothermal crystallization of SAPO-34 using 1-propylpyridinium hydroxide ([PrPy]OH) as a structural directing agent was conducted. The effects of different synthesis parameters on the nucleation and crystallization of SAPO-34 were systematically investigated. It was found that by carefully adjusting the parameters, pure and fully crystalline SAPO-34 could be synthesized in a shorter time compared to previous studies. The prepared SAPO-34 also exhibited high activity in esterification reactions. By using microwave heating, a conversion rate of 91.5% with 100% selectivity towards propyl levulinate was achieved within 20 minutes.

Organosilane-assistant synthesis of hierarchical SAPO-34 aggregates with superior MTO performance

Chao Sun, Aijuan Zhao, Yaquan Wang, Ziyang Wang, Jingjing Zhao, Taotao Zhao, Wenrong Liu, Mingxue Shi, Jiaxin Lu, Shuhui Wu, Lingzhen Bu

Summary: The hierarchical SAPO-34 aggregates were synthesized with the assistance of organosilane TPED and using morpholine as the template. Different amounts of TPED led to varying morphologies, compositions, and acid properties of the resulting aggregates. The addition of TPED played a pivotal role in the formation of hierarchical SAPO-34 aggregates, which exhibited significant improvement in methanol to olefin reaction compared to conventional SAPO-34.

Li Han, Lulu Guo, Shaozong Xue, Zheng Wang, Tianliang Lu, Jun Xu, Yuzhong Zhan, Jianfeng Wang

Summary: In this study, hierarchical porous SAPO-34 zeolite with excellent catalytic properties was successfully prepared using a one-step hydrothermal synthesis method by introducing water-soluble polyacrylamide (PAM) hydrogel into the conventional SAPO-34 synthesis system. Compared to conventional microporous SAPO-34, the hierarchically structured SAPO-34 exhibited significantly longer catalytic lifetime (740 min) and improved selectivity for light olefins up to 87.5% in the MTO reaction.

Thermal Alteration in Adsorption Sites over SAPO-34 Zeolite

Guangchao Li, Tatchamapan Yoskamtorn, Wei Chen, Christopher Foo, Jianwei Zheng, Chiu Tang, Sarah Day, Anmin Zheng, Molly Meng-Jung Li, Shik Chi Edman Tsang

Summary: This study investigated the structural transformation of adsorptive active sites in SAPO-34 zeolite under different temperatures using acetone as a probe molecule. The combination of solid-state nuclear magnetic resonance, in situ variable-temperature synchrotron X-ray diffraction, and in situ diffuse-reflectance infrared Fourier-transform spectroscopy revealed that acetone chemisorption can convert the classical Bronsted acid site adsorption mode to an induced Frustrated Lewis Pairs adsorption mode at increasing temperatures. Ab-initio molecular-dynamics simulations supported this facile conversion. This work highlights the importance of dynamic structural alteration of active sites in zeolites at elevated temperatures.

Shen Xue-Feng, Ding Jia-Jia, Liu Hong-Xing

Summary: The introduction of mesopores and downsizing of SAPO-34 crystals enhance its diffusion efficiency and catalytic activity in methanol-to-olefin reactions. Amphiphilic molecules were designed and used as co-structure directing agents, resulting in the formation of hierarchical SAPO-34 zeolites with smaller crystal sizes. These zeolites showed improved selectivity and catalytic performance compared to conventional SAPO-34.

Post synthesis of hierarchical SAPO-34 via citric acid etching: Mechanism of selective desilication

Tao Zheng, Haiyan Liu, Peng He, Rui Zhang, Xianghai Meng, Chunming Xu, Hongtao Liu, Yuanyuan Yue, Zhichang Liu

Summary: This study investigates the influence of acid concentration on the physicochemical properties of SAPO-34 catalysts and elucidates the mechanism of selective desilication using different concentrations of citric acid solutions. The results show that the concentration of citric acid determines the manufacturing of hierarchical pore structure and the extraction of specific silicon species. The resistance of Si-O-Si and Si-O-Al bonds near or in different silicon species is responsible for the selective desilication by citric acid. The distribution of silicon species and the selective desilication have a coupling effect on the generation of secondary pores and the strength and amount of acid sites. The acid-treated SAPO-34 exhibits improved performance in the methanol-to-olefins reaction.

An Al-sol gelation strategy for the synthesis of robust hierarchical SAPO-34 with enhanced ethylene selectivity

Baorong Wang, Lina Zhou, Peixin Rui, Zheng Wu, Wenfeng Zhang, Yibin Luo, Weilin Liao, Xingtian Shu

Summary: An industrial aluminum sol gelation strategy was developed to enhance the ethylene selectivity and catalytic stability of SAPO-34 in the MTO process. The aluminum gel partially erodes the SAPO-34 crystals and creates intra-crystalline mesopores. The erosion and adsorption of aluminum species are more significant under higher pH value and gelation temperature conditions. The gelation strategy prevents hydration of the crystals but leads to the reassembly of silicon species, increasing the strong acid centers. The increased coke brings about more ethylene selectivity and slightly decreases propylene and butene selectivity.

Etching behavior of TEAOH in the post-synthesis of hierarchical SAPO-34

Bing Hu, Wenxin Chen, Xiaojin Wang, Guoliang Mao, Mingjian Luo

Summary: The etching behavior of TEAOH in the post-synthesis of hierarchical SAPO-34 was investigated, and the results showed that the solubility of SAPO-34 decreases while the dissolution rate increases with the raise of temperature. The etching is believed to start with the break of Al-O(H)-Si bond and then break the Al-OH-related Al-O-P bonds and the new exposed inner Al-O(H)-Si bonds. Low-temperature etching favors the dissolution of Al-OH-related Al-O-P bonds and behaves as a layer-to-layer peel-off process, while moderate- and high-temperature etching leads to the formation of abundant mesopores and fragmentation of crystals.
