청구항

A carbon particle filter comprising carbon particles bonded into a filter block by a low melt index polymeric material having a melt index of less than about 1 gram per 10 minutes as determined by ASTM D 1238 at 190 degrees C. and 15 kilograms load, whereby said polymeric material will tackify at elevated temperatures without becoming sufficiently liquid to substantially wet the carbon particles. A carbon particle filter comprising: an inner shell of bonded 80 to 400 U.S. Series mesh screen carbon particles bonded to each other; an outer shell of bonded ...
