这篇专题评论和分析旨在为其他人提供一些见解，以战略发展新的工艺技术在21世纪世纪符合传统的愿望，绿色和/或环境化学。与其纠缠于现有的方法或逐步发展，不如就那些提供最大回报和绿色效益的目标和方法提供指导。催化剂和催化剂是多种方法的关键部分，但采取这些方法时必须对技术替代方案的生命力有一定的预期，并考虑经济、政治、社会需求和总能源需求等总体问题。将强调在设计和修改新的化学过程中考虑能源使用的重要性。将举例说明考虑任何新的替代工艺的总能量输入和输出的重要性。当这样做时，很明显，几种流行的方法并不是真的那么绿色。讨论了改进现有产品的机会，重点是以最低的能源和材料成本寻求戏剧性的突破性工艺改进。
This topical review and analysis seeks to provide others with some insight to strategies for the development of new process technologies in the 21st century which align with the traditional desires of green and/or environmental chemistry. Rather then dwelling on existing approaches or step-wise developments, guidance is offered about those targets and approaches which offer the greatest reward and green benefits. Catalysis and catalysts are a key parts of multiple approaches, but those approaches must be taken with some anticipation about the vitality of the technological alternative that is considered in view of overall issues of economics, politics, societal demands, and total energy requirements. The importance of considering energy usage in designing and modifying new chemical processes will be emphasized. Examples will be given to illustrate the importance of considering the total energy input and output of any new alternative process. When this is done, it becomes apparent that several popular approaches are not really so green. Opportunities for improvement to existing products are discussed with a focus on seeking dramatic, breakthrough process improvements with minimal energy and materials costs.
