Crambe Orientalis Bitkisinin Hidrotermal Yöntemle NaF/Al2O3 Katalizörü Varlığında Sıvılaştırılması, Katalizör Oranının Sıvı Ürün İçeriğine Etkisi
Abstract
Hidrotermal sıvılaştırma, yüksek basınç ve sıcaklık altında biyokütlenin sulu ortamda sıvılaştırılması işlemidir. Bu işlem, biyokütlenin enerji ve malzeme dönüşümü için çevre dostu bir yöntem olarak kabul edilmektedir. HTL işlemi için uygun katalizörlerin seçimi oldukça önemlidir. Katalizörler, HTL işlemi verimliliğini artırarak daha yüksek kaliteli ürünler elde etmeyi ve aynı zamanda enerji tüketimini azaltarak çevre dostu bir süreç sağlamayı mümkün kılar. Yapılan çalışmada Crambe orientalis bitkisinin hidrotermal sıvılaştırılmasında katalizör olarak NaF/Al2O3 kullanılmıştır. Alüminaya yüklenen NaF miktarına göre 3 farklı katalizör sentezlenmiştir. Reaksiyon sıcaklığı 325 oC bekleme süresi 30 dakika olarak belirlenmiştir. Katalizörlerin ağırlıkça miktarlarının sıvı ürün elementel içeriği üzerindeki etkisi incelenmiştir. En yüksek enerji değeri, NaF-2 katalizörü varlığında ağırlıkça %25’lik oranda elde edilmiştir.

Liquefaction of Crambe Orientalis Plant in The Presence of NaF/Al2O3 Catalyst by Hydrothermal Method, The Effect of Catalyst Ratio on Liquid Product Content
Abstract
Hydrothermal liquefaction is the process of liquefying biomass in an aqueous medium under high pressure and temperature. This process is recognized as an environmentally friendly method for energy and material conversion of biomass. The selection of suitable catalysts for the HTL process is very important. Catalysts make it possible to obtain higher quality products by increasing the efficiency of the HTL process and at the same time to provide an environmentally friendly process by reducing energy consumption. In the study, NaF/Al2O3 was used as a catalyst in the hydrothermal liquefaction of Crambe orientalis plant. Three different catalysts were synthesized according to the amount of NaF loaded on the alumina. The reaction temperature was determined as 325 oC and the holding time was 30 minutes. The effect of the amount by weight of the catalysts on the elemental content of the liquid product was investigated. The highest energy value was obtained at a rate of 25% by weight in the presence of NaF-2 catalyst.
