Influence of changing particle structure on the rate of gas-solid gasification reactions. Final report, July 1981-March 1984

Description: The objetive of this work is to determine the changes in the particle structure of coal as it undergoes the carbon/carbon dioxide reaction (C + CO/sub 2/ ..-->.. 2CO). Char was produced by heating the coal at a rate of 25/sup 0/C/min to the reaction temperatures of 800/sup 0/C, 900/sup 0/C, 1000/sup 0/C and 1100/sup 0/C. The changes in surface area and effective diffusivity as a result of devolitization were determined. Changes in effective diffusivity and surface area as a function of conversi… more

Intelligent optical design program

Description: Described is a general approach to the development of computer programs capable of designing image-forming optical systems without human intervention and of improving their performance with repeated attempts. The approach utilizes two ideas: (1) interpretation of technical design as a mapping in the configuration space of technical characteristics and (2) development of an intelligent routine that recognizes global optima. Examples of lens systems designed and used in the development of the gen… more

Review of proposed EPA ambient lead criteria standard document. Final report. Task assignment No. 10

Description: The proposed October 1983 EPA ambient lead criteria document, Air Quality Criteria for Lead is reviewed from the perspective of DOE's policies and programs and addresses potential impacts on energy production and energy-intensive industries. Following an introduction, the study is organized in five subsequent sections. Section 2.0 addresses environmental and health effects of exposure to lead. Section 3.0 reviews sources of lead emissions. Section 4.0 presents information on lead concentrations… more
