Catalyst for aromatization of alkanes, process of making and process of using thereof
摘要：
A catalyst of a gallium zeolite on which platinum (Pt/Ga-ZSM-5) has been deposited may be used for aromatization of alkanes having two to six carbon atoms per molecule, such as ethane, propane, butane, etc., to aromatics, such as benzene, toluene and xylenes (BTX). The gallium zeolite contains gallium and silicon in the framework of the zeolite structure. The zeolite structure may be of MFI, FAU, TON, MFL, VPI, MEL, AEL, AFI, MWW or MOR, but preferably, the zeolite has a MFI structure, more preferably is ZSM-5 MFI zeolite. According to the IUPAC recommendations, an example of the sodium form of the zeolite would be represented as: |Nax·(H2O)z|[GaxSiyO2y+3x/2]−MFI where x=0.1-25; y=60-100; and z=0.1-10. Platinum may be deposited on the gallium zeolite by ion exchange or impregnation.
摘要（中）：

可以使用其上沉积有铂（Pt / Ga-ZSM-5）的镓沸石的催化剂用于将每分子具有2-6个碳原子的烷烃如乙烷，丙烷，丁烷等芳构化成芳族化合物 ，如苯，甲苯和二甲苯（BTX）。 镓沸石在沸石结构的框架中含有镓和硅。 沸石结构可以是MFI，FAU，TON，MFL，VPI，MEL，AEL，AFI，MWW或MOR，但优选沸石具有MFI结构，更优选ZSM-5MFI沸石。 根据IUPAC的建议，沸石钠形式的一个例子可以表示为：<？in-line-formula description =“In-line Formulas”end =“lead”？> | Na x （H 2 O 2）z H 2 y + 2 x 3 x O 2 x 3 / 2] - MFI <？in-line-formula description =“In-line Formulas”end =“tail”？>其中x = 0.1-25; y = 60-100; z = 0.1-10。 铂可以通过离子交换或浸渍沉积在镓沸石上。
