Description
Известен способ приготовлени катализатора дл конверсии ОКиси углерода путем смешени углекислых солей меди и цинка с хроМовым антидридо,м с последующим ynaipHisaнием , сушкой и таблетиро вамием катализаторной массы.A known method of preparing a catalyst for the conversion of oxyal carbon by mixing carbonic salts of copper and zinc with chromium antidrido, m followed by ynaipHis, drying and tabletting the catalyst mass.
С целью получени катализатора, активного в интервале температур 150-175°С с остаточным проденто.м окиси углерода в конвертированном газе 0,1-0,3%, -предлагаетс го.товить двухкОМпонентный катализатор с применением в качестве основного исходного сырь углекислой соли меди или гидрата окиси меди и хромового ангидрида в таком соотношении , чтО|бы содержание СгаОз в пересчете на roTOiBbm катализатор составл ло от 8 до 20 вес. %.In order to obtain a catalyst that is active in the temperature range of 150-175 ° C with a residual carbon monoxide in the converted gas of 0.1-0.3%, it is proposed to put a two-component catalyst using the carbon dioxide salt as the main feedstock. or hydrate of copper oxide and chromic anhydride in such a ratio that its content would be 8 to 20 weight, in terms of the roTOiBbm catalyst. %
При м е р. 1 вес. ч. хромового ангидрида СгОз раствОр ют в 3 вес. ч. дистиллированной воды. В отдельном сосуде готов т суспензию основной углекислой соли меди СиСОз Cui(OiH)2 в дистиллированной воде в соотношении 1 : 1. В суспензию основной углекислой соли меди при тщательном перемешивании постепенно добавл ют раствО)р хромового ангидрида в количестве, соответствую.щем 15% СгаОз в готовом катализаторе. Катализаторную массу интенсивно .перемешивают 2-3 час, затем, не прекраща перемешивани , упаривают до в зкой консистенции. После этого в зкую катализаторную Aiaccy выливают на противни и сушат на воздухе при 120-130° не менее 4 час. Катализатор измельчают и таблетируют на та блето.чной машине с да1влением прессовани не менее 1600 кгс/см2.An example. 1 weight. CrO3 chromic anhydride dissolved in 3 wt. including distilled water. In a separate vessel, a suspension of basic carbonate of copper CuSO (OiH) 2 in distilled water in a ratio of 1: 1 is prepared. To the suspension of basic carbonate of copper, with vigorous stirring, solution of chromic anhydride is gradually added in an amount corresponding to 15% Sgoaz in the finished catalyst. The catalyst mass is intensively stirred for 2-3 hours, then, without stopping the stirring, evaporated to a viscous consistency. After that, the viscous catalyst Aiaccy is poured onto trays and dried in air at 120-130 ° for at least 4 hours. The catalyst is crushed and pelletized on that machine with a pressing of at least 1600 kgf / cm2.
Удельна поверхность катализатора равна 20-45 , насыпной вес катализатора 1,16 кг/мз. Механическа прочность Hai раздавливание 90-98 кгс/см.The specific surface of the catalyst is 20–45, the bulk density of the catalyst is 1.16 kg / m3. Mechanical strength Hai crush 90-98 kgf / cm.
