Bu çalışmada,
mezogözenekli alümina destekli bimetalik Ni ve Co katalizörler sıralı emdirme
yöntemiyle hazırlanmışlardır. Hazırlanan mezogözenekli bimetalik katalizörlerin
aktiviteleri 750 oC'de metanın kuru reformlanma reaksiyonunda test
edilmiştir. Katalizörlerin reaksiyon öncesi ve/veya sonrası N2
adsorpsiyon/desorpsiyon, XRD, TPR, SEM/EDX ve TG/DT analizleri yürütülmüştür.
TPR analizleri, Ni ve Co metallerinin katalizör yapısına emdirme sırasının
katalizör yapısındaki metallerin indirgenebilirliğini etkilediğini
göstermiştir. Co-Ni içerikli bimetalik katalizörlerin hazırlanmasında emdirme
sırasının katalizör içindeki metallerin indirgenmelerini ve dolayısıyla
katalitik performanslarını önemli ölçüde etkilediği gösterilmiştir. Önce Ni
sonra Co yüklenerek hazırlanan katalizörde kobaltın daha fazla indirgenmiş
olduğu ve dolayısıyla Co@Ni@SGA katalizörünün daha kararlı ve yüksek aktivite
gösterdiği bulunmuştur. Bimetalik Ni-Co katalizörler metanın kuru reformlanma
reaksiyonuna yüksek aktivite gösterirken, karbon oluşumuna da yüksek direnç
göstermişlerdir. Metanın kuru reformlanma reaksiyonunda yüksek aktivite
gösteren Co@Ni@SGA katalizörünün üzerinde biriken karbon miktarı (kütlece
%3,6), Ni@Co@SGA katalizörüne (kütlece %2,1) göre daha yüksektir. Elde edilen
ürün dağılımındaki H2/CO oranı 0,78 olarak belirlenmiştir.

In this study,
mesoporous alumina supported bimetallic Ni-Co catalysts were synthesized using
sequential impregnation method. The synthesized catalysts were tested in dry
reforming of methane at 750 oC. Before and/or after activity test, N2
adsorption/desorption, XRD, TPR, SEM/EDX, and TG/DT analyses were performed for
the catalysts. TPR analysis showed that impregnation sequence of Ni and Co
metals effects reducibility of the metal in the structure of the catalysts. It
was shown that impregnation sequence of Ni-Co bimetallic catalysts significantly
effects the reducibility of metals in the structure and accordingly the
catalytic performance of these catalysts. It was found that cobalt was more
reducible in the catalyst which was prepared by impregnation of Ni first
followed by impregnation of Co. Co@Ni@SGA catalyst prepared this way showed
more stable and high catalytic activity. Bimetallic Ni-Co catalysts showed high
activity with a high resistance to coke formation, in dry reforming of methane.
Amount of coke formation (3.6% by wt) over Co@Ni@SGA catalyst (which showed
higher activity in dry reforming of methane) was higher than the amount of coke
(2.1% by wt) over Ni@Co@SGA catalyst. H2/CO ratio in product stream
was obtained as 0.78.
