GOALI - Microwave Reactor Applications for Biomass and Green Technologies

Steven L. Suib和Anne M. Gaffney 0827800康涅狄格大学和Lummus Technologies（LT）之间的GOALI项目专注于制备各种纳米尺寸的沸石（Y，<$）、介孔TUD-1和混合物，这些材料用于许多催化过程。将使用新的原位混合（I）超声喷嘴（N）微波（M）方法（IN、IM、INM）。这些方法具有以下优点：使用非传统反应器，大大减少合成时间，生产具有比常规方法更均匀的晶体尺寸的非常小（纳米尺寸）的沸石，并且是在大气压下的连续工艺。合成、表征和催化研究[用（Y）烷基化，甘油转化为丙烯醛的生物质转化（<$）]将在UCONN完成，样品将被送往LT，用于异丁烷与C3-C5烯烃的烷基化，以形成高辛烷值烷基化汽油。这些无害环境、商业上可行的催化应用将受益于沸石尺寸的减小和传热传质的改善。智力优势：合成中间体和纳米沸石的合成、生长、成核和表征（拉曼、NMR、FTIR、酸度、X射线粉末衍射、BET、孔径分布等）的基础知识在石油催化、吸附和传感器中是重要的。Suib（UCONN）和Gaffney（LT）过去曾在氧化催化剂方面进行过合作，共同开发了INM方法，并且都在沸石和分子筛方面拥有丰富的经验。这项工作推进了使用各种M方法生长沸石和介孔材料的基础研究，以了解通常控制纳米材料尺寸和形状的因素。学生将访问LT，以帮助催化实验和LT的研究人员将访问UCONN，以帮助合成实验。这两个设施都有开展这项工作的资源，其他实验，如小角X射线散射（SAXS），将与阿贡国家实验室的P. Thiyagajaran博士合作进行。具体方面的假设应导致更好地理解INM，沸石和介孔合成，成核，粒度和传质效应，表征，催化活性，选择性和稳定性。LT的AlkyClean反应器专注于长期（14天）运行，将用于研究活性，选择性，突破时间，罗恩和UCONN研究人员提供的催化剂的可回收性。更广泛的影响：学术和工业合作者的研究技能和教育将被整合到该计划中。微波工程和科学是由PI和外展人员在康州大学在我们的孩子也是科学家（KAST）K-12夏季计划，由CEM和里程碑公司共同赞助的一个星期。KAST和其他外展方案针对康涅狄格州主要城市（哈特福德、布里奇波特）的多样化和代表性不足的群体，并为残疾学生提供一个特殊的实验室。康州大学的本科生（专业和REU）和研究生将参与这项研究，并积极参加季度联席会议。联合化学工程/将继续提供催化和纳米科学方面的化学课程。沸石合成和沸石微波合成的本科实验室实验是本科课程的一部分，每年都要进行。招聘具有不同和代表性不足的背景的研究生是一项持续的活动，由康州大学提供财政支持。LT距离UCONN有两小时车程。这项工作的结果将被出版，专利，并在国家和国际会议上提出。这种合作的附加值来自于所有研究人员的不同经验，并且将完成任何一个单独组织都不可能完成的工作。目前的固体酸催化剂（SAC）市场增长率为50，000桶/物流日（BPSD）或当前全球装机容量的2.5%;每年300万磅的催化剂体积;以及SAC商业化前10年的平均市场价值为3600万/年。2009年，国际新闻学会将组织一次关于微波催化作用的国际研讨会。

Steven L. Suib and Anne M. Gaffney0827800 This GOALI project between the University of Connecticut and Lummus Technologies (LT) focuses on the preparation various nano-size zeolites (Y, â), Mesoporous TUD-1, and mixtures, which are used in many catalytic processes. Novel in situ mixing (I) ultrasonic nozzle (N) microwave (M) methods (IN, IM, INM) will be used. These methods have advantages of use of non-traditional reactors, highly reduced synthesis times, production of very small (nano-sized) zeolites with more uniform crystal size than conventional methods, and being continuous processes at atmospheric pressure. Synthesis, characterization, and catalytic studies [alkylation with (Y), biomass conversion of glycerol to acrolein (â)] will be done at UCONN and samples will be sent to LT for Alkylation of isobutane with C3-C5 olefins to form high octane alkylate gasoline. These environmentally sound, commercially viable catalytic applications will benefit from a reduced zeolite size and improved heat and mass-transfer. Intellectual Merit: Fundamental knowledge of synthesis, growth, nucleation, and characterization (Raman, NMR, FTIR, acidity, X-ray powder diffraction, BET, pore size distributions, others) of synthetic intermediates and nano-size zeolites is important in petroleum catalysis, adsorption, and sensors. Suib (UCONN) and Gaffney (LT) have collaborated in the past on oxidation catalysts, co-developed the INM method, and both have considerable experience with zeolite and molecular sieves. This work advances fundamental studies of growth of zeolites and Mesoporous materials using various M methods to understand factors that control size and shapes of nano-materials in general. Students will visit LT to help with catalytic experiments and LT researchers will visit UCONN to help with synthesis experiments. Resources are available at both facilities to carry out this work, and other experiments such as small angle X-ray scattering (SAXS) will be done in collaboration with Dr. P. Thiyagajaran at Argonne National Laboratories. Specific aspects of the hypotheses should lead to an improved understanding of INM, zeolite and mesopore synthesis, nucleation, particle size and mass transfer effects, characterization, catalytic activity, selectivity, and stability. LT's AlkyClean reactors with a focus on longterm (14 d) runs will be used to study activity, selectivity, breakthrough time, RON, and recyclability of catalysts provided by UCONN researchers. Broader Impacts: Research skills and education of academic and industrial collaborators will be integrated in this program. Microwave engineering and science is presented for one week by the PI and outreach personnel at UCONN in our Kids are Scientists Too (KAST) K-12 summer program, co-sponsored by CEM and Milestone Corporations. KAST and other outreach programs target diverse and underrepresented groups in major CT cities (Hartford, Bridgeport) and offer a special laboratory for students with disabilities. Undergraduate (majors and REU) and graduate students at UCONN will be involved in this research and actively participate in quarterly joint meetings. Joint chem. eng./chemistry courses in catalysis and nano-science will continue to be offered. Undergraduate lab experiments in zeolite synthesis and in microwave syntheses of zeolites are part of the undergraduate curriculum and are done each year. Recruiting of graduate students with diverse and underrepresented backgrounds is an ongoing activity financially supplemented by UCONN. LT is two hours away by car from UCONN. Results of this work will be published, patented, and presented at national and international meetings. Added value in this collaboration comes from the diverse experience of all of the researchers and work will be done that is not possible by either sole organization alone. The current solid acid catalyst (SAC) market growth rate is 50,000 barrels per stream day (BPSD) or 2.5% of current worldwide installed capacity; a 3 million pound per year catalyst volume; and an SAC average market value for the first 10 years of commercialization of 36 million/year. An international symposium on microwaves in catalysis will be organized by the PIs in 2009.
