Ethylation of Benzene with Ethane over MFI Zeolite-Supported Pb Catalyst
Conversion of a short alkane such as ethane into chemical feedstocks instead of alkene becomes important for efficient use of natural gas and refinery off-gas. Here direct ethylation of benzene with ethane into ethylbenzene was attempted. Preceding studies clarified catalytic activity of Pt-loaded MFI-type zeolite. In addition, for a similar reaction, i.e., methylation of benzene with methane, we previously found catalytic activity of Co/MFI. Based on these backgrounds, various metal elements supported by zeolites were investigated as catalysts for a reaction between ethane and benzene. Pt, Pb, Zn, Mo, Co, and Ga/MFI showed high activity for ethylation of benzene with ethane. Among them, Pb/MFI showed high reaction rate for formation of desired products (ethylbenzene, styrene and diethylbenzene), while the others brought side reactions, i.e., formation of C3−5 aliphatic hydrocarbons, toluene, naphthalene, and its derivatives. Pb/MFI showed stable activity, while Pt, Zn, and Mo/MFI showed deactivation due to carbonaceous formed by the side reactions.
期刊介绍：
Catalysis Letters aim is the rapid publication of outstanding and high-impact original research articles in catalysis. The scope of the journal covers a broad range of topics in all fields of both applied and theoretical catalysis, including heterogeneous, homogeneous and biocatalysis.
The high-quality original research articles published in Catalysis Letters are subject to rigorous peer review. Accepted papers are published online first and subsequently in print issues. All contributions must include a graphical abstract. Manuscripts should be written in English and the responsibility lies with the authors to ensure that they are grammatically and linguistically correct. Authors for whom English is not the working language are encouraged to consider using a professional language-editing service before submitting their manuscripts.
