    Description / Table of Contents: Abstract На никельхромитном катализаторе общая схема восстановления NO в N2 зависит от природы восстановителя восстановление NO молекулярным водородом протекает, преимущественно, через стадию образования N2O, восстановление NO оксидом углерода, преимущественно, путем непосредственного превращения NO в N2, т. э. минуя стадию образования промежуточного соединения N2O.
    Notes: Abstract The route of NO reduction to N2 over nickel chromite catalyst is dependent on the nature of the reducing agent. NO reduction by dihydrogen proceeds mainly through the step of N2O formation, whereas NO reduction to N2 by carbon monoxide is mainly direct without a step of N2O formation.

    Effect of oxygen on NO reduction over nickel chromite catalysts (1988)
    Springer
    Reaction kinetics and catalysis letters 36 (1988), S. 33-37

    Description / Table of Contents: Abstract На массивном и нанесенных на γ-Al2O3 и фаянсовые носители никельхромитных катализаторах восстановление NOx в смесях NOx−CO (H2)−O2 происходит с высокими скоростями. При объемной скорости 10 тыс·ч−1 полное восстановление оксидов азота водородом наблюдается при 400–450°C, оксидом углерода — при 450–500°C. Последнее позволяет рекомендовать никельхромитный катализатор в качестве основы при создании промышленного катализатора обезвреживания кислородсодержащих газовых выбросов от оксидов азота.
    Notes: Abstract Reduction rates of NOx in HOx+CO(H2)+O2 mixtures over a pure nickel chromite catalyst and samples supported on γ-Al2O3 and faience are high. At a space velocity of 10,000 h−1, the complete reduction of nitrogen oxides by hydrogen and by carbon monoxide is achieved at 400–450°C and 450–500°C, respectively. Hence these catalysts can be recommended as a basis to develop commercial catalysts for NOx removal from oxygen-containing exhaust gases.
