The possibility of the preparation of molecular sieving carbon from Saran waste was studied. Saran waste was first decomposed and carbonized at 800°C. Then, adding 7.4 wt% of coal tar pitch and 13.0 wt% of sulfite pulp waste liquor, Saran chars were granulated into sphere using disc-type pelletizer. Thus obtained spherical particles were heated at 600-1000°C.
The granulated Saran carbons heated at 600 or 700°C have been found to have negligible capacities for iso-butane and significant capacities for n-butane, indicating 5 A molecular sieve properties similar to zeolite 5 A. Saran carbons prepared at 800-1000°C adsorbed considerable amount of iso-butane and their capacities for iso-butane decreased with increase of heat treatment temperature.
