The aim of the present work is to examine the feasibility of production of structural active carbon from polyvinylformal form. The optimal condition of carbonization and the effect of initial pore size distribution of the carbonized material on pore development by steam activation were experimentally investigated. The results are as follows. 1) At heating rates below 3.1°C-min-1, the raw PVF form was carbonized homogeneously, and the pore size of the carbonized material thus obtained was uniformly distributed in a region smaller than 2 × 10″9 m. 2) By steam activation of the carbonized material at about 700°C, micro-pores were developed selectively, and then active carbon rich in micro-pores smaller than 7 x 10-10 m was produced. 3) From adsorption experiments of a binary gas mixture, this active carbon was shown to have an excellent molecular sieving effect for mixtures like benzen-cyclohexane. From these results, it seemed highly possible to produce structural active carbon sufficiently applicable to practical use from the PVF form. 1984, The Society of Chemical Engineers, Japan.
