International Classification:

US Classification:

502432

Abstract:

Microporous carbonaceous materials, useful in the storage of gaseous fuels such as methane and natural gas, are improved through modification of their microporous structure in a post-carbonization process. This modification is done by heat treatment in an oxidizing atmosphere containing carbon dioxide with or without other diluting gases such as nitrogen, argon or water-vapor. The post-carbonization process involved modifying a starting microporous carbon with heat treatment in which the carbon is contacted with a carbon dioxide-containing atmosphere. This new treatment can be favorably applied either to selected and commercially available activated microporous carbons which have been designed for applications other than fuel gas storage or to synthetic microporous carbons proposed for storage of light gases.

US Classification:

260659A

Abstract:

A cyclic process having reduced hydrocarbon emission is provided for oxyhydrochlorination of ethylene to produce ethylene dichloride employing substantially pure oxygen as feed to the oxyhydrochlorination unit and recycling a major portion of the residual gas stream from which ethylene dichloride has been recovered as condensate, wherein reactant feed rates are adjusted to maintain recycle gas stream composition within specified limits.
