In this study, due to the high contribution of the transportation sector to generate CO2 emissions, an evaluation for the best scenario of the replacement of petroleum derived fuels by renewable and sustainable alternatives was assessed with a multi collative approach suggesting the second-generation bioethanol as the most promising one. In this context, this paper focused on the practices over the past 23 years in the following four countries; Turkey, China, Sweden, and Brazil, with a comparative regression analysis between the CO2 emissions generated from the consumptions of total energy and biofuels. Accordingly, a curve-fitting and an estimation on the formation of CO2 emissions with the incrementing blends of gasoline by 3 to 100% of bioethanol was forecasted for 2020 to 2030. The outcomes of the comprehensive research indicated the international and national benefits of biofuel use, thus, promoting the potential integration of bioethanol in the Turkish transportation sector.

Bu çalışmada, ulaşım sektörünün CO2 emisyonu oluşumuna yüksek katkısı nedeniyle, petrol türevi yakıtların yenilenebilir ve sürdürülebilir alternatiflerle ikame edilmesinin en iyi senaryosuna yönelik bir değerlendirme, ikinci nesil biyoetanolün kullanımının önerildiği çoklu bir yaklaşımla değerlendirilmiştir. Bu bağlamda, bu makale, belirtilen dört ülkede son 23 yıldaki uygulamalara odaklanmıştır; Türkiye, Çin, İsveç ve Brezilya. Toplam enerji ve biyoyakıt tüketiminden kaynaklanan CO2 emisyonları arasında karşılaştırmalı bir regresyon analizi ile İlgili ülkeler incelenmiştir. Buna göre, 2020 ila 2030 yılları için biyoetanolün %3 ila %100 oranında artan benzin karışımlarıyla CO2 emisyonlarının oluşumuna ilişkin bir eğri uydurma ve bir tahmin öngörülmüştür. Kapsamlı araştırmanın sonuçları biyoyakıt kullanımının uluslararası ve ulusal faydaları gösterilmiştir, böylece biyoetanolün Türk ulaşım sektörüne potansiyel entegrasyonunun teşvik edilmesi önerilmiştir.enerjili hava kollektörleri (GEHK) genellikle mahal ısıtma ve tarımsal ürünlerin kurutulmasında kullanılmaktadır. GEHK’nde yutucu plaka ve akışkan arasındaki ısı transferinin düşük olmasından dolayı ısıl verimleri düşüktür. Bu çalışmada ısıl verimin yükseltilmesine yönelik olarak yeni bir yutucu plaka geometrisi tasarlanmış ve imal edilmiştir. Konik yayların çapraz sıralı olarak monte edildiği yutucu plakalı ve karşılaştırma amaçlı düz yutucu plakalı kolektörlerden ibaret test düzeneği kurulmuştur.
