Abstract:
A process for producing an adsorbent block comprising a first step of preparing a dispersion system comprising a liquid dispersion medium mainly having porous material powder as a solid disperse phase, and forming a molded block from said dispersion system, anda second step of removing said liquid dispersion medium from said molded block to bind mainly said porous material powder, so as to obtain an adsorbent block formed to have continuous flow paths, characterized in that said dispersion system contains a binder that is capable of binding said porous material powder and an area increasing agent that disappears by heating said molded block at a particular temperature, at which said binder does not disappear, and said second step comprises a liquid dispersion medium removing step of removing said liquid dispersion medium, and a heating step of heating said molded block at said particular temperature.
