CARBON ADSORBENTS FOR NATURAL-GAS STORAGE

Composite carbons were produced by combining, and subsequently pyrolys ing, polyvinylidene copolymer latexes and AX-21 carbon. These carbons were produced in a monolithic form, enabling them to fit compactly int o a given storage volume. The composites demonstrated that the latex p olymer could enter the undesirable large voids and interparticle space s in the superactivated carbon and remain there after pyrolysis, thus eliminating some of the wasted space which is always problematic when attempting to maximize gas storage on a volume basis. The best composi tes produced contained approximately 60% superactive carbon and 40% po lymer carbon. The polymer carbon from Saran latex was considered the b est binder.
