项目摘要

Proposed Abstract Title:SusChEM: Development of Nickel Catalysts for the Conversion of Biomass-derived Oils to Fuel-like HydrocarbonsBiodiesel, which consists of fatty acid methyl esters or so-called FAMEs, is a fuel derived from vegetable oils and animal fats which has gained much attention in recent years as a renewable alternative to diesel fuel. However, a number of issues stemming from the high oxygen content of biodiesel,such as relatively poor storage stability and engine compatibility issues, have limited its widespread application, along with a lack of suitable feedstocks. This award, to Professors Mark Crocker and Eduardo Santillan-Jimenez at the University of Kentucky Center for Applied Energy Research, aims to circumvent these shortcomings by developing an improved process for the conversion of vegetable oils and animal fats to hydrocarbons which are chemically indistinguishable from petroleum-derived diesel, and hence, which can be used as a drop-in substitute for diesel. A key feature of this process is the use of a catalyst based on inexpensive, earth-abundant nickel, as opposed to the use of expensive precious metal catalysts. An added benefit of this research is that it will provide students with hands-on experience in the field of biofuels, thus ultimately helping to satisfy the growing demand for highly skilled scientists and engineers in the renewable energy sector. A second objective of this project is the establishment of new outreach efforts directed at local Kentucky schools. Specifically, a "biofuels game" will be developed, which teaches K-12 students basic concepts about petroleum fuels, biofuels, and the relative economic and environmental costs associated with their production and use. The entire focus of the award is aligned with the SusChEM philosophy.Catalytic decarboxylation/decarbonylation (deCOx) has been proposed as an alternative to hydrotreating for the conversion of lipids and bio-oils to produce renewable drop-in hydrocarbon fuels. Indeed, deCOx is not only more energy and hydrogen efficient, but it proceeds over benign metal catalysts, and does not require the sulfided catalysts used in hydrotreating. The investigators have shown that the performance of specific catalysts comprising earth-abundant and inexpensive Ni can rival that of the expensive precious metals (Pd and Pt) commonly used to catalyze deCOx. Preliminary results have shown that promotion of Ni catalysts with small amounts of Cu or Sn leads to enhancements in the efficiency of the process. However, the underlying principles of the catalytic phenomena at play are not thoroughly understood. This project aims at a more complete understanding of these promotion effects, which in turn should allow further improvements to the system. To this end, four main objectives will be addressed: 1) the selectivity of Ni catalysts towards fuel-like hydrocarbons will be optimized by fine-tuning the activity of the catalytically active phase; 2) the resistance to deactivation shown by these catalysts will be improved by modifying the active phase electronically and/or morphologically; 3) fundamental structure-activity relationships will be established to rationalize the effect of these changes on the active phase; and 4) mechanistic and kinetic studies will be employed to elucidate the reaction mechanism and kinetic parameters for representative feed-catalyst combinations.
拟定摘要标题:SusChEM:生物质油转化为燃料类烃的镍催化剂的开发生物柴油由脂肪酸甲酯或所谓的FAME组成,是一种源自植物油和动物脂肪的燃料,近年来作为柴油的可再生替代品而受到广泛关注。然而,源自生物柴油的高氧含量的许多问题,例如相对差的储存稳定性和发动机相容性问题,已经限制了其广泛应用,沿着的是缺乏合适的原料。该奖项授予了肯塔基州大学应用能源研究中心的Mark Crocker和Eduardo Mallan-Jimenez教授,旨在通过开发一种将植物油和动物脂肪转化为碳氢化合物的改进方法来克服这些缺点,该碳氢化合物在化学上与石油衍生柴油难以区分,因此可以用作柴油的替代品。该工艺的一个关键特征是使用基于廉价的、地球上丰富的镍的催化剂,而不是使用昂贵的贵金属催化剂。这项研究的另一个好处是,它将为学生提供生物燃料领域的实践经验,从而最终有助于满足可再生能源领域对高技能科学家和工程师日益增长的需求。该项目的第二个目标是针对当地肯塔基州学校开展新的外联工作。具体而言,将开发一个“生物燃料游戏”,向K-12学生传授有关石油燃料、生物燃料以及与其生产和使用相关的相对经济和环境成本的基本概念。该奖项的全部重点与SusChEM的理念相一致。催化脱羧/脱羰(deCOx)已被提议作为加氢处理的替代方案,用于将脂质和生物油转化为可再生的直接碳氢燃料。事实上,deCOx不仅更节能和氢效率更高,而且它在良性金属催化剂上进行,并且不需要加氢处理中使用的硫化催化剂。研究人员已经表明,包含地球丰富和廉价的Ni的特定催化剂的性能可以与通常用于催化deCOx的昂贵贵金属(Pd和Pt)相媲美。初步结果表明,用少量的Cu或Sn促进Ni催化剂导致该方法的效率提高。然而,催化现象的基本原理还没有被彻底理解。该项目旨在更全面地了解这些促进效果,从而进一步改进该系统。为此,将提出四个主要目标:1)通过微调催化活性相的活性来优化Ni催化剂对燃料类烃的选择性; 2)通过电子和/或形态上改性活性相来改善这些催化剂所显示的抗失活性;(3)建立基本的构效关系,合理化这些变化对活性相的影响;和4)机理和动力学研究将用于阐明代表性进料-催化剂组合的反应机理和动力学参数。
