Recovery of active components from carrier or monolythic catalysts

摘要

The active components are recovered from carriers or full catalysts by reacting them with anhydrous hydrogen halide at 20-900 degrees C and 0.01-10 bar and fractionally sepg. them at 50-900 degrees C and 0.001-5 bar. In the case of catalysts from the gp. Cu, Fe, Ru, Ce, Bi, Ni, Co, Ga, Nd, V, Mo, Ti, Zr, W, Pt, Pd, Sb, Ag, Y, Sn, Zn, In, Nb, Mn, Cr, La or their mixts., the reaction is carried out in the absence of O2.
