ABOUT PAUL'S WORK
Paul Dauenhauer is a chemical engineer developing new technologies for converting biomass—materials derived from organic, renewable sources—into the chemical building blocks of products that are currently sourced from fossil fuels. Most consumer products contain petroleum-based plastics, rubber, detergents, and other chemicals that harm the environment in several ways: from the extraction of the petroleum, to the energy inputs and waste materials associated with the production process, to the limited biodegradability of the resulting products. With expertise that spans reaction chemistry (specific chemical transformations) and catalysis engineering (accelerating reactions), Dauenhauer is opening new pathways for mitigating the environmental impacts of commodity chemicals.

Dauenhauer has demonstrated new methods for producing high yields of p-xylene (a key chemical for making polyester and plastics like soda bottles) and isoprene (a critical component of synthetic rubbers) from renewable resources such as wood, crop waste, and other types of refuse. The costs associated with his approach and quality of the resulting chemicals are comparable to production from petrochemical sources. He has also developed an entirely new class of surfactants (chemical compounds that enable cleaning agents to mix with water) from sugar and fatty acids with the potential to replace petrochemical-based versions used in a large array of cleanser formulations, including detergents, soaps, and personal care products. Dauenhauer’s surfactants have increased biodegradability and exhibit novel and desirable properties not found in conventional detergents.

Dauenhauer is also tackling the critical problem of how to efficiently transform raw (solid) biomass into liquids and gases suitable for use as chemical feedstocks. He and colleagues found that application of oscillating energy waves to a heterogeneous solid catalyst increases the speed of chemical reactions well beyond the previously assumed catalytic “speed limits.” In addition, he developed the Polyarc reactor, a chemical microreactor that enables more efficient measurement of the organic carbon content in fuel mixtures. Dauenhauer’s ability to integrate fundamental research with applied chemical technologies is bringing us closer to greener consumer products and a carbon-neutral future.

BIOGRAPHY
Paul Dauenhauer received a BS (2004) from the University of Wisconsin and a PhD (2008) from the University of Minnesota. From 2008 to 2009, Dauenhauer served as a senior research engineer in the Core R&D Reaction Engineering group of the Dow Chemical Company. He was a faculty member of the Department of Chemical Engineering at the University of Massachussetts at Amherst from 2009 to 2014, prior to joining the Department of Chemical Engineering and Materials Science at the University of Minnesota, where he is now Lanny Schmidt Honorary Professor. Dauenhauer’s articles have been published in such scientific journals as Green Chemistry, ACS Catalysis, Journal of Physical Chemistry, and Energy and Environmental Science, among others.

IN PAUL'S WORDS
Iaminspiredtoengineernewchemicalprocessesforcarbon-freefuelsthatcanstorewindandsolarpoweranddrivecompletedecarbonizationoftheworld’senergysystem.


Civilization is in a race against time to develop the sustainable energy and materials required to expand and continue a healthy quality of life. As our original resource of fossil fuels contributes to catastrophic global climate change and environmental pollution, new manufacturing processes are utilizing renewable resources to make unique fuels and clever new materials that have zero environmental impact. I am inspired to engineer new chemical processes for carbon-free fuels that can store wind and solar power and drive complete decarbonization of the world’s energy system. At the same time, conversion of non-food trees and grasses into biodegradable and recyclable materials enables sustainable use of materials to protect our food, clothe our bodies, and compose our automobiles and devices.

关于保罗的工作
保罗-道恩豪尔是一名化学工程师，他正在开发将生物质--来自有机、可再生资源的材料--转化为目前来自化石燃料的产品的化学构成部分的新技术。大多数消费品都含有以石油为基础的塑料、橡胶、洗涤剂和其他化学品，它们在几个方面对环境造成了损害：从石油的开采，到与生产过程有关的能源投入和废料，再到所生产产品有限的生物降解性。凭借横跨反应化学（特定的化学转化）和催化工程（加速反应）的专业知识，道恩豪尔正在为减轻商品化学品对环境的影响开辟新的途径。

道恩豪尔已经展示了从木材、作物废料和其他类型的垃圾等可再生资源中生产高产量的对二甲苯（制造聚酯和苏打水瓶等塑料的关键化学品）和异戊二烯（合成橡胶的一个关键成分）的新方法。与他的方法相关的成本和所产生的化学品的质量与从石化资源中生产的产品相媲美。他还从糖和脂肪酸中开发了一类全新的表面活性剂（使清洁剂能够与水混合的化合物），有可能取代大量清洁剂配方中使用的石化产品，包括洗涤剂、肥皂和个人护理产品。多恩豪尔的表面活性剂具有更高的生物降解性，并表现出传统洗涤剂所不具备的新颖和理想的特性。

道恩豪尔还在解决如何有效地将原始（固体）生物质转化为适合用作化学原料的液体和气体这一关键问题。他和同事们发现，将振荡能量波应用于异质固体催化剂可以提高化学反应的速度，远远超过以前假设的催化 "速度极限"。此外，他还开发了Polyarc反应器，这是一种化学微反应器，能够更有效地测量燃料混合物中的有机碳含量。道恩豪尔将基础研究与应用化学技术相结合的能力，使我们更接近更环保的消费品和碳中性的未来。

个人简历
保罗-道恩豪尔在威斯康星大学获得学士学位（2004年），在明尼苏达大学获得博士学位（2008年）。从2008年到2009年，道恩豪尔在陶氏化学公司的核心研发反应工程组担任高级研究工程师。2009年至2014年，他是马萨诸塞大学阿默斯特分校化学工程系的教师，之后加入明尼苏达大学化学工程和材料科学系，现在是Lanny Schmidt荣誉教授。道恩豪尔的文章发表在《绿色化学》、《ACS催化》、《物理化学杂志》、《能源与环境科学》等科学杂志上。

保罗的话
我的灵感来自于为无碳燃料设计新的化学过程，这些过程可以储存风能和太阳能，并推动世界能源系统的完整碳化。


人类文明正在与时间赛跑，以开发可持续的能源和材料，以扩大和延续健康的生活质量。由于我们原有的化石燃料资源导致了灾难性的全球气候变化和环境污染，新的制造工艺正在利用可再生资源来制造独特的燃料和对环境无影响的巧妙的新材料。我受到启发，为无碳燃料设计新的化学工艺，可以储存风能和太阳能，推动世界能源系统的完全脱碳。同时，将非食物的树木和草转化为可生物降解和可回收的材料，能够可持续地使用材料来保护我们的食物，为我们的身体穿上衣服，并组成我们的汽车和设备。
