Abstract
Bu çalışmada, hidrotermal olarak sentezi gerçekleştirilen Cr-MCM-41 (%3 Cr kütlece) katalizörü üzerinde izobütan dehidrojenasyonu için reaksiyon hız ifadesi geliştirilmiştir. Reaksiyon hızı belirleme çalışmaları diferansiyel reaktör şartlarında, sabit katalizör miktarı (0,05g) üzerinden, farklı izobütan başlangıç konsantrasyonlarında (0,002-0,01mol/L) ve farklı sıcaklıklarda (723K-873K) gerçekleştirilmiştir. Cr-MCM-41 katalizörü üzerinde yürütülen reaksiyon için aktivasyon enerjisi 55 kJ/mol olarak belirlenmiştir. Ticari olarak temin edilen Pd membran reaktör sisteminde 823K ve 873K sıcaklıklarda izobütan dehidrojenasyonu incelenmiştir. Reaksiyon uygulamalarının gerçekleştirildiği membran reaktör sistemi modellenmiştir. Model denkliklerinin oluşturulmasında izotermal reaktör ve yatışkın durum kabulleri yapılmıştır. Model denkliklerinin çözümünde MATLAB R2011a/ODE45 programından yararlanılmıştır. 823K’de membran reaktörde deneysel belirlenen dönüşüm değerlerinin model sonuçları ile uyum gösterdiği tespit edilmiştir. 873K’de model sonuçları ile deneysel sonuçlar arasındaki farklılık ise membranın 873K’de yan reaksiyonlar için aktif hale gelmesi ile açıklanmıştır
