PROCESS FOR PRODUCING FUEL ABSORBENT

摘要

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 coatings and a carrier may be used to control fuel evaporation loss in automobile canisters or boiler fuel tanks.
