Abstract
The invention relates to a process for producing a fuel absorbent, which comprises the steps of: dissolving an organic polymer having a function of trapping fuel in a solvent to produce a polymer solution; adding a crosslinking agent to said polymer solution to allow said organic polymer to react in the presence of said crosslinking agent; and collecting, after the completion of the crosslinking reaction, the resultant fine polymer gel particles. The invention also relates to a porous fuel absorbent produced by the above process comprised of fine cross-linked organic polymer formed into particles. The above fuel absorbent along with the coatings and a carrier may be used to control fuel evaporation loss in automobile canisters or boiler fuel tanks.
