Air‐Jet Experimental Study and Modeling of Attrition Behavior for Fluid Catalytic Cracking Catalysts

Ghazvini Saba Foroutan; Ebrahimi Ali Afshar

摘要

Abstract >Fluid catalytic cracking (FCC) processes employ microspheroidal catalyst particles, which play a significant role in the most important part of a refinery. These catalysts are subject to attrition because of the nature of FCC process circulation in the reactor regenerator. Attrition tests according to the American Society for Testing and Materials (ASTM) standards were carried out for two FCC catalysts in both fresh and spent forms. Attrition characteristics and catalyst resistance were investigated by particle size distribution and scanning electron microscopy. Response surface methodology using a central composite design was applied to simulate the mass distribution of samples in the downstream. This method was used to investigate the effect of time on attrition behavior of fresh and spent forms of the catalysts. </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 XMLNS =“http://www.wiley.com/namespaces/wiley”type =“main”xml：lang =“en”> <标题类型=“main”>抽象</ title> >流体催化裂化（FCC）方法采用微散催化剂颗粒，在炼油厂最重要的部分中起着重要作用。由于FCC工艺循环在反应器再生器中的性质，这些催化剂受到磨损。根据美国测试和材料（ASTM）标准的耗材测试是针对新鲜和花费的两种FCC催化剂进行的。通过粒度分布和扫描电子显微镜研究了磨损特性和催化剂抗性。应用了使用中央复合设计的响应面方法来模拟下游样品的质量分布。该方法用于研究催化剂新鲜和花卉形式的磨损行为的效果。</ p> </摘要> </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-16566/'>《Chemical Engineering & Technology: Industrial Chemistry -Plant Equipment -Process Engineering -Biotechnology》</a> <b style="margin: 0 2px;">|</b><span>2018年第11期</span><b style="margin: 0 2px;">|</b><span>共10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=Ghazvini Saba Foroutan&option=202" target="_blank" rel="nofollow">Ghazvini Saba Foroutan;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Ebrahimi Ali Afshar&option=202" target="_blank" rel="nofollow">Ebrahimi Ali Afshar;</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>Faculty of PetrochemicalsIran Polymer and Petrochemical InstituteP.O.
