Cement manufacturing is a high energy consuming and highly polluting process. Cement producers are trying to reduce the energy and environmental costs by using alternative fuels and raw materials through their research and development. Alkaline environment, high temperature and long processing time allow cement kiln to burn a wide range of waste and hazardous materials. This paper summarizes an...
Mobile sources are among the largest contributors of four hazardous air pollutants--benzene, 1,3-butadiene, acetaldehyde, and formaldehyde--in urban areas. At the same time, federal and state governments are promoting the use of alternative fuel vehicles as a means to curb local air pollution. As yet, the impact of this movement toward alternative fuels with respect to toxic emissions has not b...
The high efficiency and energy density of miniaturized fuel cells provide an attractive alternative to batteries in the portablepower-generation market for consumer and military electronic devices [1-3]. The best fuel cell efficiency is typically achieved with hydrogen, but safety and reliability issues remain with current storage options. Consequently, there is continued interest in reforming ...
