摘要

Abstract > Intermetallic GaPd <sub>2</sub> is a highly selective and stable catalyst for the semi‐hydrogenation of acetylene. Knowledge of the underlying reaction kinetics is essential to gain a deeper understanding of the selective hydrogenation on this catalytic material. To date, there has been no experimental kinetic data published for this reaction on a well‐defined intermetallic catalyst possessing isolated active sites. Kinetic measurements are performed at 140–200?°C, revealing an apparent activation energy of 29(2)?kJ?mol ?1 . GaPd <sub>2</sub> is shown to be the first binary catalyst material, which shows a positive reaction order (0.89) with respect to acetylene at 200?°C. The influences on the extent of acetylene conversion, specific activity and selectivity to ethylene, ethane, and higher hydrocarbons are determined by a 2 4 factorial experiment following a design of experiments approach. Temperature and pressure have the strongest impact on these values. The results allow optimal operation for achieving high ethylene yields. A comparison of the reaction kinetics on GaPd <sub>2</sub> with experimental results obtained for GaPd reveals different orders of reaction of H <sub>2</sub> and C <sub>2</sub> H <sub>2</sub> on the two compounds. </abstract> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> <div class="translation abstracttxt"> <span class="zhankaihshouqi fivelineshidden" id="abstract"> <span>机译：</span><Abstract Type =“Main”XML：Lang =“en”> <标题类型=“main”>抽象</ title> >金属间隙<sub> 2 </ sub>是一种高选择性和稳定的催化剂乙炔的半氢化。知识潜在的反应动力学是必要的，以便更深入地了解该催化材料的选择性氢化。迄今为止，在具有分离的活性位点的明确定义的金属间催化剂上没有公开这种反应的实验动力学数据。动力学测量在140-200Ω℃下进行，显示表观活化能量为29（2）°（2）°ΔKJ？mol Δ1</ sup>。 Gapd <sub> 2 </ sub>是第一二元催化剂材料，其在200℃下相对于乙炔显示正反应顺序（0.89）。对乙烯，乙烷和较高烃的乙炔转化，特异性活性和选择性程度的影响由实验方法设计后的2 4 </ sup>阶乘实验确定。温度和压力对这些值具有最强的影响。结果允许实现高乙烯产率的最佳操作。对Gapd <sub> 2 </ sub>的反应动力学的比较GAPD的实验结果显示出H <sub> 2 </ sub>和C <sub> 2 </ sub> h <sub的不同阶数>两种化合物上的2 </ sub>。 </ p> </ abstract> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> </div> <div class="record"> <h2 class="all_title" id="enpatent33" >著录项</h2> <ul> <li> <span class="lefttit">来源</span> <div style="width: 86%;vertical-align: text-top;display: inline-block;"> <a href='/journal-foreign-16300/'>《Chemphyschem: A European journal of chemical physics and physical chemistry》</a> <b style="margin: 0 2px;">|</b><span>2017年第18期</span><b style="margin: 0 2px;">|</b><span>共9页</span> </div> </li> <li> <div class="author"> <span class="lefttit">作者</span> <p id="fAuthorthree" class="threelineshidden zhankaihshouqi"> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Zimmermann René R.&option=202" target="_blank" rel="nofollow">Zimmermann René R.;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Hahn Tobias&option=202" target="_blank" rel="nofollow">Hahn Tobias;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Reschetilowski Wladimir&option=202" target="_blank" rel="nofollow">Reschetilowski Wladimir;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Armbrüster Marc&option=202" target="_blank" rel="nofollow">Armbrüster Marc;</a> </p> <span class="z_kbtnclass z_kbtnclassall hoverxs" id="zkzz" style="display: none;">展开▼</span> </div> </li> <li> <div style="display: flex;"> <span class="lefttit">作者单位</span> <div style="position: relative;margin-left: 3px;max-width: 639px;"> <div class="threelineshidden zhankaihshouqi" id="fOrgthree"> <p>Materials for Innovative Energy Concepts Faculty of Natural Sciences Institute of ChemistryUniversity of Technology ChemnitzStra?e der Nationen 62 09107 Chemnitz Germany;</p> <p>Leibniz Institute for Catalysis at the University of Rostock (LIKAT Rostock)Albert-Einstein-Str. 29a 18059 Rostock Germany;</p> <p>Department of Chemistry and Food ChemistryDresden University of Technology01062 Dresden Germany;</p> <p>Materials for Innovative Energy Concepts Faculty of Natural Sciences Institute of ChemistryUniversity of Technology ChemnitzStra?e der Nationen 62 09107 Chemnitz Germany;</p> </div> <span class="z_kbtnclass z_kbtnclassall hoverxs" id="zhdw" style="display: none;">展开▼</span> </div> </div> </li> <li > <span class="lefttit">收录信息</span> <span style="width: 86%;vertical-align: text-top;display: inline-block;"></span> </li> <li> <span class="lefttit">原文格式</span> <span>PDF</span> </li> <li> <span class="lefttit">正文语种</span> <span>eng</span> </li> <li> <span class="lefttit">中图分类</span> <span><a href="https://www.zhangqiaokeyan.com/clc/1186.html" title="物理化学（理论化学）、化学物理学">物理化学（理论化学）、化学物理学;</a></span> </li> <li class="antistop"> <span class="lefttit">关键词</span> <p style="width: 86%;vertical-align: text-top;"> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=gallium&option=203" rel="nofollow">gallium;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=heterogeneous catalysis&option=203" rel="nofollow">heterogeneous catalysis;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=intermetallic phases&option=203" rel="nofollow">intermetallic phases;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=kinetics&option=203" rel="nofollow">kinetics;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=palladium&option=203" rel="nofollow">palladium;</a> </p> <div class="translation"> 机译：镓;异质催化;金属间阶段;动力学;钯;
