Abstract

Artan nüfus ve gelişen teknoloji ile birlikte enerjiye duyulan ihtiyaç da hızla artmaktadır. Çevre kirliliği giderek önemli bir sorun haline gelmekte ve mevcut enerji rezervleri de hızla tükenmektedir. Hidrojen enerjisi çevre dostu, yenilenebilir bir enerji kaynağı olması sebebiyle bilimsel çalışmaların en önemli araştırma alanlarından biri haline gelmiştir. Bu çalışmada fıstık küspesinin hidrojen ve biyogaz potansiyeli araştırılmıştır. Çalışma oda koşullarında gerçekleştirilmiş; hidrojen ve biyogaz verimini etkileyen önemli faktörlerden biri olan pH’ın beş farklı değeri denenmiş ve optimum pH değeri saptanmıştır. Verimin en yüksek olduğu pH=6 değerinde elde edilen biyogaz miktarı gram fıstık küspesinde 55.54 ml olarak hesaplanmıştır. Çalışmada biyohidrojen miktarının hesaplanması için gaz kromotografi (GC) cihazı kullanılmış ve veriler kaydedilmiştir. Fıstık küspesinden biyohidrojen eldesi için optimum pH değeri 6 olarak belirlenmiş ve bu pH’da gram başına elde edilen maksimum hidrojen miktarı 5.99 ml olarak ölçülmüştür. Araştırmada fıstık küspesinin hidrojen potansiyeline sahip olduğu ve enerji elde etmede alternatif bir kaynak olabileceği saptanmıştır.
