National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

The Aerospace Corporation Shell 405 Catalyst Evaluation Program. Volume I. Physical and Catalytic Properties.

AD858913

Publication Date	1969
Personal Author	King, S. M.; Marx, P. C.; Taylor, D.
Page Count	42
Abstract	Results are presented for series of physical tests performed on Shell 405 catalysts and carriers to determine the principal attrition and loss mechanisms occurring during motor operation. It is shown that the development of free space in a reaction chamber can lead to serious attrition losses. Results of vibration, mechanical crushing, thermal shock, and thermal expansion measurements are also discussed. A laboratory technique was devised for studying catalytic activity. A thermocouple was used to measure the temperature transient occurring when a drop of hydrazine contacts catalyst. The effect of the initial pressure (vacuum to 760 torr) and temperature (20 to 75C) on the reaction induced temperature change was studied and is discussed. Some correlations with motor performance data are made. (Author)
