Abstract
Nitrozinių dujų išlakų oksidinimo katalizatoriaus-kalco hidroksilikatas C-S-H (1) yra skiriamas nitrozinių dujų išlakose esančių mažų koncentracujų NO katalitiniam oksidinimui ir susidariusių NO2 šalinimui jo sorbcijos metodu ir gali būti pritaikomas chemijos, energetikos ir kitų pramonės įmonių į atmosferą išmetamų išlakų nukenksminimui.@Nitrozinių dujų išlakų oksidinimas vykdomas 50-150 °C temperatūroje naudojant katalizatorių, sintetinį kalcio hidrokailikatą C-S-H (1) eliminuojantį katalizatoriaus aktyvų paviršių blokuojantį vandens garų poveikį. Be to, sintetinis katalizatorius - kalcio hidroksilikatas C-S-H (1) turi savo struktūroje 1-1,5 molekulės ceolitino pobūdžio vandens ir yra sintetinamas iš AIF3 gamybos atliekų ir pramoninių kalkių, esant pradinio mišinio CaO ir SiO2 moliniam santykiui C/S=0,8; sintezės temperatūrai 90-95 °C ir trukmei 3 val.@Vykdant nitrozinių dujų išlakų oksidinimą siūlomu katalizatoriumi, jis gali būti atliekamas prei palyginant žemų temperatūrų (50-150°C) ir su nedidelėmis energijos sąnaudomis proceso terminiam aktyvavimui ir sintetinio katalizatoriaus pagaminimui.Nitros Gas Oxidation Catalyst-Calco Hydroxylate CSH (1) is used for catalytic oxidation of low concentrations of NO concentrates from nitrosate gases and removal of NO2 generated by its sorption method and can be applied to the decontamination of atmospheric emissions from chemical, energy and other industries. the oxidation of the emissions is carried out at a temperature of 50-150 ° C using a catalyst, which eliminates the water vapor effect of the active surface of the catalyst by eliminating the calcium calcium hydrocyclic acid CSH (1). In addition, the synthetic catalyst, calcium hydroxylate CSH (1), has in its structure 1-1.5 molecules of zeolite water and is synthesized from the production waste and industrial lime of AIF3 with a molar ratio C / S = 0.8 of the initial mixture CaO and SiO2. ; Synthesis temperature 90-95 ° C for 3 hours @ Oxidation of nitrous gas with the proposed catalyst can be accomplished by comparing low temperatures (50-150 ° C) with low energy consumption for process activation and synthesis of synthetic catalyst.
