Özet:

 Within the scope of this study, the effects of fast pyrolysis of sunflower oil cake on obtained product yields and product properties were investigated under non-catalytic condition and using clinoptilolite catalyst. The percentages of moisture, ash, volatile matter and fixed carbon content of sunflower oil cake used as raw material within the scope of the research were determined as 5.92, 6.08, 71.30 and 16.70, respectively. According to the its elemental analysis results, the percentages of C, H, N and S were determined as 42.06, 6.26, 6.93, 0.00, respectively. The heating value was calculated as 17.13 MJkg. For this aim firstly, the effects of heating rate 100, 200, 300min, pyrolysis temperature 400, 500, 600 and catalyst percentages 5, 10, 15 on product yields biochar, biooil and pyrolysis gas were investigated. In the experiments conducted with the addition of clinoptilolite catalyst during fast pyrolysis of sunflower oil cake, it was determined that the catalyst did not change the solid product yield much, it considerably reduced the liquid product yield and increased the gas product yield. In the biochar samples, the highest heating value was obtained as 22.95 MJkg at 300Cmin heating rate and 500 pyrolysis temperature conditions without catalyst. When the microscopic structure SEM analysis of the biochar samples was examined, it was understood that the porosity increased compared to the raw material. It was determined that the heating values of the pyrolysis gas samples obtained under the non catalyst-free condition were higher than those of the samples obtained under the non-catalytic condition. The highest lower heating value for obtained gas samples was obtained as 29.05 MJNm³ at 400C temperature and 100Cmin heating rate conditions Bio oil samples obtained by pyrolysis of sunflower oil cake at different temperatures and different heating rate with and without catalyst were examined by GC-MS method, and it was determined that especially phenol compounds Phenol, Phenol, 2-methoxy- were found in almost every sample. In addition, aromatic compounds such as Pyrazine-methyl, Pyrazine 2,6-dimethyl-CAS 2,6-Dimethylpyrazine have also been detected.

 Bu çalışma kapsamında ayçiçeği küspesinin hızlı pirolizinin katalizörsüz koşulda ve klinoptilolit katalizörü kullanılarak yapılmasının, elde edilen ürün verimleri ve ürün özellikleri üzerine etkileri araştırılmıştır. Araştırma kapsamında hammadde olarak kullanılan ayçiçeği küspesinin nem içeriği 5.92, kül içeriği 6.08, uçucu madde yüzdesi 71.30 ve sabit karbon yüzdesi 16.70 olarak belirlenmiştir. Elemental analiz sonuçlarına göre C, H, N ve S yüzdeleri sırasıyla 42.06, 6.26, 6.93, 0.00 olarak saptanmıştır. Isıl değeri ise 17.13 MJkg olarak hesaplanmıştır. Araştırma kapsamında ilk olarak, ısıtma hızı 100, 200, 300 dk, piroliz sıcaklığı 400, 500, 600 ve katalizör yüzdelerinin 5, 10, 15 ürün verimleri biyokömür, biyoyağ ve piroliz gazı üzerine etkileri incelenmiştir. Ayçiçeği küspesinin hızlı piroliz işleminde klinoptilolit katalizörü eklenmesiyle yapılan denemelerde, katalizörün katı ürün verimini önemli düzeyde değiştirmediği, sıvı ürün verimini oldukça düşürdüğü ve gaz ürün verimini artırdığı belirlenmiştir. Biyokömür örneklerinde en yüksek üst ısıl değer, katalizörsüz koşulda 500  sıcaklık ve 300 dk ısınma hızında 22.95 MJkg olarak elde edilmiştir. Biyokömür örneklerinin mikroskobik yapısı incelendiğinde SEM analizi hammaddeye göre gözenekliliğin arttığı anlaşılmıştır. Katalizörsüz koşulda elde edilmiş olan piroliz gazı örneklerinin alt ısıl değerlerinin katalizörlü koşulda elde edilen örneklerinkine göre daha yüksek olduğu belirlenmiştir. Elde edilen gaz örneklerinde en yüksek alt ısıl değer 400  sıcaklıkta, 100 dk ısınma hızında 29.05 MJNm³ olarak elde edilmiştir. Ayçiçeği küspesinin farklı sıcaklıklarda, farklı ısıtma hızlarında katalizörlü ve katalizörsüz koşulda pirolizi ile elde edilmiş olan biyoyağ örnekleri GC-MS yöntemiyle incelenmiş, özellikle fenol bileşiklerinin Phenol, Phenol, 2-methoxy- hemen her numunede olduğu saptanmıştır. Ayrıca Pyrazine-methyl, Pyrazine 2,6-dimethyl- CAS 2,6-Dimethylpyrazine gibi aromatik bileşiklerde tespit edilmiştir.
