Process for producing spherical particles of furfuryl alcohol resin, spherical particles of furfuryl alcohol resin produced thereby, and spherical carbon particles and spherical activated carbon particles obtained using the same

Abstract

Provided is a process for advantageously producing spherical particles of furfuryl alcohol resin without irradiating the reaction system with ultrasonic waves and without using a harmful aldehyde as a starting material. In the process, furfuryl alcohol is subjected to resinification and curing to form spherical fine particles of furfuryl alcohol resin. More specifically, the furfuryl alcohol is subjected to a self-condensation with an acid catalyst having a pKa of less than 1.5 in the presence of a protective colloid and then heated for curing to form spherical particles of furfuryl alcohol resin.
