Description

мого раствора количество паллади , извлеченного из отработанного палладиевого катализатора на носителе - окиси алюмини , возрастает в 3 раза, а расход сол ной кислоты снижаетс  в 2,5 - 5 раз.The amount of palladium extracted from the spent palladium catalyst on the carrier, alumina, increases by a factor of 3, and the consumption of hydrochloric acid decreases by a factor of 2.5 to 5.

Предлагаемый раствор был испытан на лабораторной установке.The proposed solution was tested in a laboratory setup.

В стекл нный реактор объемом 200 мл загружают 5:5 мл раствора, содержащего, вес. %:НС1 3,0; FeCU 1,5; HjO 95,5,, и внос т 15 г отработанного палладиевого катализатора (0,75 вес. % паллади ) на носителе - окиси алюмини , содержащего 112 мг паллади . Содержимое реактора интенсивно перемешивают 2 час при 70°С. После проведени  прбцесса раствор не содержит продуктов разложени  носител . Выдел ют из раствора известными методами 111 мг паллади .A 5: 5 ml solution containing, in weight, is fed into a 200 ml glass reactor. %: HC1 3.0; FeCU 1.5; HjO 95.5 ,, and 15 g of the spent palladium catalyst (0.75 wt.% Palladium) are introduced on a support, alumina, containing 112 mg of palladium. The contents of the reactor are intensively stirred for 2 hours at 70 ° C. After completion of the process, the solution does not contain decomposition products of the carrier. 111 mg of palladium was isolated from the solution by known methods.
