Abstract:

 Hydrothermal liquefaction HTL is the process of liquefying biomass under high pressure and temperature and is widely used to provide environmentally friendly energy and material conversion. In the HTL process, the selection of the right catalysts is critical to increase process efficiency and obtain products with high energy value. For this purpose, in this study, CoTiO2, MnTiO2 and CoMnTiO2 catalysts were synthesized, characterized by analysis methods such as SEM, SEM-EDX, XPS and ICP-OES and used in the HTL process of the Xanthium strumarium plant. The reaction temperature in HTS was determined as 275, 300 and 325 C and the waiting time was determined as 30 minutes. At the end of the experiments, it was observed that the experiments with catalysts increased the amount of liquid product. Elemental and GC-MS analyzes of the obtained liquid products were performed. The highest energy value was obtained in the presence of the MnTiO2 catalyst.

 Hidrotermal sıvılaştırma HTS, biyokütlenin yüksek basınç ve sıcaklık altında sıvı hale getirilmesi sürecidir ve çevre dostu enerji ve malzeme dönüşümü sağlamak için yaygın olarak kullanılmaktadır. HTS sürecinde, doğru katalizörlerin seçimi, süreç verimliliğini artırmak ve enerji değeri yüksek ürünler elde etmek açısından kritik öneme sahiptir. Bu amaçla bu çalışmada CoTiO2, MnTiO2 ve CoMnTiO2 katalizörleri sentezlenmiş, SEM, SEM-EDX, XPS ve ICP-OES gibi analiz yöntemleri ile karakterize edilmiştir ve Xanthium strumarium bitkisinin HTS prosesinde kullanılmıştır. HTS prosesinde reaksiyon sıcaklığı 275, 300 ve 325 C bekleme süresi ise 30 dakika olarak belirlenmiştir. Deneyler sonunda katalizörlü denemelerin sıvı ürün miktarını artırdığı gözlemlenmiştir. Elde edilen sıvı ürünlerin Elementel ve GC-MS analizleri yapılmıştır. En yüksek enerji değeri, MnTiO2 katalizörü varlığında elde edilmiştir.
