The Technology of Tail Gases Purifying in Nitric Acid Plants and Design of deN2O and deNOx Reactors—Review

Autor: Paweł Capała, Monika Ruszak, Anna Rudawska, Marek Inger, Marcin Wilk

Publikováno v: Applied Sciences, Vol 13, Iss 13, p 7492 (2023)

The tightening standards of nitrogen oxides emission from industrial plants encourage nitric acid producers to search for new efficient solutions to meet the stringent emission limits. Industrial practice and the patent literature show that the effec

Two-Stage Catalytic Abatement of N2O Emission in Nitric Acid Plants

Autor: Marek Inger, Bartosz Moszowski, Monika Ruszak, Jakub Rajewski, Marcin Wilk

Publikováno v: Catalysts, Vol 10, Iss 9, p 987 (2020)

Different variants for abatement of N2O emission from nitric acid plants with the use of catalysts developed at Łukasiewicz-INS were analyzed. Activity tests on a pilot scale confirmed the high activity of the studied catalysts. A two-stage catalyti

The influence of NOx presence on the catalytic N2O decomposition over the supported double-promoted cobalt spinel catalyst

Autor: Monika Ruszak, Marcin Wilk, Jakub Rajewski, Marek Inger

Publikováno v: Chemical Papers. 73:1979-1986

The supported double-promoted cobalt spinel catalyst has been tested for N2O decomposition in the model and real gas streams (tail gas) from nitric acid plant. Activity tests carried out in the model gas stream showed a high activity of the developed

THE ROLE OF INTERMEDIATE CALCIUM ALUMINATE PHASES IN SOLID STATE SYNTHESIS OF MAYENITE (Ca12Al14O33)

Autor: Piotr Pietrzyk, Stefan Witkowski, Monika Ruszak, Zbigniew Sojka, Andrzej Kotarba

Publikováno v: Functional Materials Letters. :183-186

Structural transformations during the synthesis of mayenite ( Ca 12 Al 14 O 33) were investigated. The samples were prepared by a solid–state reaction and the transformations were researched by means of XRD, Rietveld analysis, SEM, and Raman spectr
