Manufacturing of plastics and other industrial chemicals depends on key chemical building blocks sourced primarily from petroleum and natural gas feedstocks. Increasingly, renewable resources such as biomass are used to make the same product or drop-in substitutes. This biomass is typically made up of crop residues or purposely grown plants that are not competitors for food agriculture. Current biobased chemicals such as hydoxymethylfurfural, furfural, and their derivatives are promising drop-in replacements for chemicals made from fossil fuels and have been identified as top platform chemicals from biorefining processes. This research project studies the manufacture of these biomass-derived platform chemicals using catalysts that can promote higher product yields and a lower environmental footprint. Parallel objectives of this project are to integrate the research activities with education and outreach programs to provide significant educational opportunities at the undergraduate and graduate education levels and to the general public. The educational outreach includes a joint course between Montana State University and the Colorado School of Mines designed as website modules and Skype-based lectures. The results of this project are being disseminated to the scientific community and implemented in course material lectures to benefit the student body at both institutions. The central theme of this collaborative project is to demonstrate that rationally designing nanocrystalline zeolites with tailored properties can lead to effective catalysts exhibiting high catalytic activity for biomass and sugar conversion into commercially useful platform chemicals. The specific objectives of this work are to: (1) develop chemical synthesis strategies to rationally design nanocrystalline zeolite catalysts, (2) understand the basic formation mechanisms governing the transformation of precursor solutions into zeolites, (3) evaluate catalytic performance of nanocrystalline zeolite catalysts for the catalytic conversion of sugars and biomass into furfural and derivatives, and (4) elucidate fundamental structure/catalytic relationships of microporous nanocrystalline catalysts in the conversion of sugars into hydoxymethylfurfural, furfural, and their derivatives. This fundamental research ties understanding of synthesis conditions to properties of the zeolite, including crystal size distribution, pore size, surface area and acid site distribution, to catalytic activity and to product yield of targeted dehydration products. The research also aims to establish novel self-assembly concepts as general synthesis methods for a broad range of zeolite catalysts that will have tunable properties and convert biomass into industrial relevant chemicals.

塑料和其他工业化学品的制造取决于主要来自石油和天然气原料的关键化学构建块。越来越多的可再生资源（例如生物质）用于制造相同的产品或替代品。该生物量通常由农作物残留物或故意种植的植物组成，这些植物不是粮食农业的竞争者。当前的生物基化学物质，例如氢氧甲基氟化学，呋喃及其衍生物是有望替代化石燃料制成的化学物质的液位替代物，并且已被确定为来自生物修补工艺的顶级平台化学物质。该研究项目研究了这些生物质衍生的平台化学物质的生产，这些催化剂可以促进较高的产品产量和较低的环境足迹。该项目的平行目标是将研究活动与教育和外展计划相结合，以便在本科和研究生教育水平以及公众提供重要的教育机会。教育外展活动包括蒙大拿州立大学和科罗拉多州矿业学校之间的联合课程，设计为网站模块和基于Skype的讲座。该项目的结果正在传播到科学界，并在课程材料讲座中实施，以使这两个机构的学生团体受益。这个协作项目的核心主题是证明具有量身定制特性的合理设计纳米晶沸石可以导致有效的催化剂，表现出高催化活性，可用于生物质和糖转换为商业上有用的平台化学品。这项工作的具体目的是：（1）制定化学合成策略以合理设计纳米晶沸石催化剂，（2）了解前体溶液转化为Zeolite的基本形成机制，（3）评估纳米晶体沸石的催化性催化性催化性的催化性催化性，用于催化型的催化性催化性，用于催化型的催化性催化型，以使其对催化型的催化性催化型催化性催化性，并将其用于催化型的催化效果。 （4）在糖转化为氢氧甲基氟化膜，毛茸茸及其衍生物中，微孔纳米晶催化剂的基本结构/催化关系。这项基本研究将对合成条件的理解与沸石的性质有关，包括晶体尺寸分布，孔径大小，表面积和酸位点分布，催化活性以及靶向脱水产物的产物产量。该研究还旨在建立新型的自组装概念作为一般合成方法，用于广泛的沸石催化剂，它们将具有可调性并将生物量转化为工业相关化学品。
