چکیده
Son günlerde yaşanan COVID-19 salgını, temiz ve yenilenebilir enerji kaynaklarının kullanımının ne derece önemli olduğunu birkez daha göstermiştir. Bu çalışmada, geleceğin kaynağı olarak düşünülen hidrojen, Ni-B katalizörleri kullanılarak NaBH4’ün hidrolizi ile üretilmiştir. Hidroliz reaksiyonu esnasında reaksiyon kinetiğine doğrudan etkisinin olduğu bilinen ortam sıcaklığı, karıştırma hızı, katı-sıvı oranı kullanılan yakıtta NaBH4 _NaOH gibi parametrelerin hızına olan etkileri yanıt yüzey metodu ayrıntılı incelenmiştir. Kullanılan metodunda deneysel çalışmalar Taguchi L9 ortogonal dizisi gerçekleştirilmiş etkinliği varyans analizi belirlenmiştir. Oluşturulan model sonucunda, maksimum hidrojen üretim hızının eldesi için optimum parametreler; sıcaklığı 347,17ºK; hızı 200,21 rpm; 2,86 mgkatalizör/mlyakıt; NaBH4--NaOH 1,04 Varyans analizine göre hızını etkileyen sırasıyla NaBH4_NaOH Buna karşılık oranının belirgin bir şekilde ortaya çıkmadığı görülmüştür. Yanıt yöntemi geliştirilen modelden elde edilen tahmin sonuçları verilerin birbirilerini doğruladığı, yapılan doğrulama deneyleri sonucunda konulmuştur.
