В стационарном слое катализатор примен ют в виде таблеток, в кип щем - в виде шарообразных частиц с раз.меро.м 0,02- 0,8 мм..Proce1S1C. Will be introduced both with a stationary catalyst and in a 1KI catalyst bed. In the stationary layer, the catalyst is applied in the form of tablets, in boiling water, in the form of spherical particles with a size of 0.02-0.8 mm.

Однако -проведение процесса в кип щем слое каталИзато(ра осложнено тем, что вследствие маленьких размеров частиц катализатора необходимы спец.иалыные пылеуловители и дополнительное выделение целевого продукта, уносимого совместно с KaTaviM3aTOpной пылью.However, the process is carried out in a fluidized bed of catalizato (it is complicated by the fact that, due to the small size of the catalyst particles, special scrubbers and additional extraction of the target product, carried out together with KaTaviM3aTOp dust, are necessary.
С целью упрощени процесса, предлагаетс .примен ть катализатор с диа.мет1ром преИ|Мущест1ве1Н«о шарооб|разны1Х частиц, равным 0,1-0,5 мм. В качестве носител целесообразно использовать юремНиавсую .кислоту. Также МОЖ1НО употребл ть и различные известные нсх;ители, например оиликагель, кизельгур, кремйиевую кислоту, диатомитовую зе.млю, окись алк мини , алюмосиликат, фосфаты 10 алюмини и железа, карбид кремни , шпинели , асбест или ажтищированный уголь.In order to simplify the process, it is proposed to apply a catalyst with a diameter of 1 m of the diameter of 0.1–0.5 mm. As a carrier, it is advisable to use the acid. Also known as ICH1NO are various known NCAs, such as silica gel, diatomaceous earth, silicic acid, diatomaceous earth, alumina oxide, aluminosilicate, aluminum and iron phosphates, silicon carbide, spinel, asbestos or agitated carbon.
В качестве активаторов палладиовых катализаторов могут быть использованы любые из известных, например -карбо ксилаты, осо5 бенйо ацетаты щелочиых и щелочноземельных металлов или металлинеские медь, золото , цивдк, кадмий, ол.О)ВО, свинец, марганец, хром, молибден, (В.ольфрам, уран, железо, кобальт , нике аь, необий, ванадий, тантал.

Кроме того, увеличиваетс обща производительность катализатора (увеличиваетс диффузионна поверх/кость 5 катализатора).As an activator of palladium catalysts, any of the known ones can be used, for example, carboxy xylates, alkali metal and alkaline earth metal benzoo acetates, or metal copper, gold, cyvdc, cadmium, ol.O.) BO, lead, manganese, chromium, molybdenum, ( Tungsten, uranium, iron, cobalt, nickel, non, vanadium, tantalum. This is largely ".And it reduces the power and quantity of dust removal devices. In addition, the overall catalyst productivity increases (diffusion overhead / bone 5 increases). isator).
