    摘要: A process for converting coal tar containing quinoline-insoluble particles (Q.I.) produces a substantially Q.I.-free coal tar pitch and a separate Q.I.-containing coal tar pitch. Dehydrated coal tar, soft coal tar pitch or hard coal tar pitch are subjected to continuous cross flow filtration in a circulation loop to obtain a substantially Q.I.-free stream and, concurrently, a Q.I.-containing stream. The two streams are then separately subjected to further fractionation, if any, to produce the substantially Q.I.-free hard coal tar pitch and separate Q.I.-containing hard coal tar pitch.

    摘要: A fire retardant flexible graphite composite is formed from particles of exfoliated flexible graphite and particles of unexfoliated graphite flake treated with an intercalating agent usually in a desired ratio based upon the strength and desired fire retardant properties of the composite. A wall or floor covering is formed by compressing the composite into a sheet and rolled into a roll.
