    摘要: A method is disclosed for the treatment of single particle iron-containing syngas (synthes.s gas) conversion catalysts comprising iron, a crystalline acidic aluminosilicate zeolite having a silica to alumina ratio of at least 12, a pore size greater than about 5 Angstrom units and a constraint index of about 1-12 and a matrix. The catalyst does not contain promoters and the treatment is applicable to either the regeneration of said spent single particle iron-containing catalyst or for the initial activation of fresh catalyst. The treatment involves air oxidation, hydrogen reduction, followed by a second air oxidation and contact of the iron-containing single particle catalyst with syngas prior to its use for the catalytic conversion of said syngas. The single particle iron-containing catalysts are prepared from a water insoluble organic iron compound.

    摘要: Hydrocarbon lubricating oils are upgraded by removing polar compounds contained therein and improving the oxidation stability thereof using an acidified sorbent, such as alumina, silica-alumina or bauxite treated with anhydrous HCl, anhydrous HBr, aqueous (NH.sub.4).sub.2 SO.sub.4 or H.sub.2 SO.sub.4. The acidified sorbent contains at least 3%, by weight of the acidified sorbent, of Cl.sup.-, Br.sup.- or SO.sub.4 .sup.= ions. The process of upgrading the lube oils is carried out at a temperature ranging from ambient to about 250.degree. F and LHSV of 0.1 - 10.
