Classification ntawm Precious Hlau Catalysts

Catalysts tuaj yeem raug cais raws li seb cov khoom siv tau raug txhawb los ntawm kev txhawb nqa:

Unsupported Hlau Catalysts:Cov no yog cov hlau catalysts tsis muaj kev txhawb nqa. Lawv tuaj yeem muab faib ua ib qho -hlau thiab alloy raws li lawv cov muaj pes tsawg leeg. Lawv feem ntau yog siv rau hauv daim ntawv ntawm lub moj khaum hlau, hlau meshes, hlau hmoov, hlau hais, hlau scraps, thiab hlau evaporation films.

Txhawb Metal Catalysts:Cov no yog cov catalysts uas cov khoom siv hlau tau txais kev txhawb nqa ntawm kev txhawb nqa. Qhov no pab txhim kho qhov tawg thiab thermal stability ntawm cov hlau tivthaiv, muab cov catalyst tsim pore qauv, zoo, thiab txhua yam muaj zog. Feem ntau kev txhawb nqa hlau catalysts yog npaj los ntawm impregnating ib tug hlau ntsev tov mus rau ib tug kev txhawb nqa, ua raws li los ntawm nag lossis daus hloov dua siab tshiab los yog thermal decomposition thiab txo.

Multi-metal Catalysts:Cov catalysts no muaj ob lossis ntau dua hlau. Piv txwv suav nrog platinum-rhenium bimetallic (los yog ntau-metallic) hloov kho catalysts txhawb nqa ntawm chlorine-muaj -alumina. Lawv muaj kev ua tau zoo dua piv rau cov platinum tau hais los saum toj no-tsuas yog hloov kho cov catalysts. Hauv cov catalysts no, ntau cov hlau uas tau txais kev txhawb nqa tuaj yeem tsim binary lossis multi- hlau pawg, ua kom muaj txiaj ntsig zoo ntawm kev sib cais ntawm cov khoom siv.
