Abstract:

 Biochars can be considered as effective base materials for PCMbiochar composites due to their high surface area and porous structures. Shape-stable PCMbiochar composites produced in this way have the potential to be used in various applications such as energy storage and thermal protection. The maximum surface area, pore sizes, and distributions of biochars produced through pyrolysis vary according to parameters such as maximum pyrolysis temperature, heating rate, and holding time. In this study, the effects of maximum pyrolysis temperature on biochar porosity were evaluated in terms of the amount of PCM impregnated into the pores. For this purpose, biochars were obtained from naturally sourced poplar sawdust using different pyrolysis maximum temperatures. BiocharPCM composites were created by impregnating PCM into the biochar pores using the vacuum impregnation method. The heat storage capacities of BiocharPCM composites were determined by Differential Scanning Calorimetry. The results showed that as the pyrolysis maximum temperature decreased, the energy storage capacities of BiocharPCM composites increased.

 Biyokömürler, yüksek yüzey alanı ve gözenekli yapıları sayesinde, FDMbiyokömür kompozitleri için etkili bir taban malzemesi olarak değerlendirilebilirler. Bu şekilde üretilen şekil kararlı FDMbiyokömür kompozitleri, enerji depolama ve termal koruma gibi farklı uygulamalarda kullanılma potansiyeline sahiptirler. Piroliz yoluyla üretilen biyokömürlerin maksimum yüzey alanı, gözenek boyutları ve dağılımları; maksimum piroliz sıcaklığı, ısıtma hızı ve bekletme süresi gibi parametrelere göre değişmektedir. Bu çalışmada maksimum piroliz sıcaklığının biyokömür gözenekliliği üzerindeki etkileri, gözenekler içerisine emdirilen FDM miktarı açısından değerlendirilmiştir. Bu amaçla doğadan elde edilen kavak talaşından, farklı piroliz maksimum sıcaklıkları kullanılarak biyokömürler elde edilmiştir. Elde edilen biyokömür gözeneklerine vakum emdirme yöntemiyle FDM emdirilerek BiyokömürFDM kompozitleri oluşturulmuştur. BiyokömürFDM kompozitlerinin ısı depolama kapasiteleri Diferansiyel Taramalı Kalorimetre ile belirlenmiştir. Elde edilen bulgular, piroliz maksimum sıcaklığının düşmesi ile BiyokömürFDM kompozitlerinin enerji depolama kapasitelerinin arttığını göstermiştir.
