Abstract: Cu is extracted from spent catalysts contg. Cu and/or oxides of Cu, Zn, Al and Cr which have been used for CO conversion, or methanol synthesis, by adjusting the mole ratio of ZnO/Al2O3 in the mixt. to 1:0.9 to 1:1.2 by addn. of ZnO and/or Al2O3, and heating the mixt. to at least 800 degrees C pref. 900-1100 degrees C for 1 hr before separating Cu from the other metals by dissolving in dilute nitric acid or an aq. soln. of an ammonium salt.

Abstract: Acetylene is prepd. by high-temp. hydrocarbon pyrolysis, using a quench oil made by the following new method. Hydrocarbon oils contg. or yielding high-boiling polynuclear aromatic cpds., pref. the aromatics-rich byproduct oils from ethylene steam crackers, are fed to a moving bed of coke, pref. indirectly heated, at a temp. of at least 400 deg.C, and pref. above 550 deg.C. The quench oil prod. may be taken as a distillate, and byproduct coke remains in the bed. The quench oil should contain at least 10 wt.%, pref. at least 15 wt.% of polynuclear aromatics of b.pt. 180-400 deg.C. A side stream of the circulating quench oil from the acetylene plant may be returned to the coke bed for removal of soot. Feedstock oils for the quench oil are cheap, frequently waste, prods., in more abundant supply than naphthalene (an alternative quench oil). The coke produced as byproduct is of good quality (purity greater than 96%, low in ash, and of useful granularity).

Abstract: Catalyst for hydrogenation of organic cpds. contains one or more complexes of Pd(O) on an inert carrier. This catalyst is very active, esp. with respect to hydrogenation of organic nitro or carbonyl cpds., nitriles, olefins and cycloolefins. The reaction is highly selective, esp. in the case of aromatic and polycyclic nitro cpds. The Pd(O) complexes are stable and firmly adhere to the carrier. The organic ligands protect Pd atoms against oxidation. The dispersion of Pd atoms is very fine. The pref. ligands include unsatd. ketones of formula (in which R1 and R6 are each H, 1-5C alkyl, phenyl or 5-8C cycloalkyl; and R2, R3, R4 and R5 are each H (pref.) or 1-5C alkyls).
