ABSTRACT
Biomass pyrolysis and gasification define as effective thermal technologies to produce sustainable hydrogen from biomass sources. The fundamental aim of this paper compare analysis of energy and exergy a pyrolysis and gasification system. The suggested process conditions occurs two main step as low and high temperature pyrolysis and gasification at 500֯C and 900֯C respectively. The analysis coupled with thermodynamic equilibrium calculate and model implement to product hydrogen with a detailed comparison of the energy and exergy performance of a downdraft gasifier and pyrolysis ipinartamplement using wood chips as the biomass materials. This paper examines energy and exergy yield of two different thermal conversion methods to produce energy. So, the optimum model conditions chose as pyrolysis at 900֯ C with lower energy consumption and not uses agent materials. The energy and exergy analyses are performed two different temperature for all process. The results from the model shows that the energy yield of pyrolysis calculate as 60% and 94% at 500֯ C and 900֯ C. The effects of changing temperature on energy and exergy yield are reported.

ÖZET
Biyokütle piroliz ve gazlaştırma sistemleri, biyokütle kaynaklarından sürdürülebilir hidrojen üretmek için etkili termal teknolojiler olarak tanımlanmaktadır. Bu makalenin temel amacı, bir piroliz ve gazlaştırma sisteminin enerji ve ekserji analizini karşılaştırmaktır. Önerilen süreç koşulları sırasıyla 500֯C düşük ve 900֯C yüksek sıcaklıkta piroliz ve 900֯C'de gazlaştırma olmak üzere iki ana aşamada gerçekleşmektedir. Termodinamik denge ile birleştirilmiş analizde, hidrojen üretimi sağlamak için deneysel sonuçlar ile modelleme birleştirilmiştir.

Bu makale, enerji üretmek için iki farklı termal dönüştürme yönteminin enerji ve ekserji verimini incelemektedir. İnceleme sonuçlarına göre, optimum model koşulları 900֯ C'de daha düşük enerji tüketimi ile ve ajan malzemeleri kullanmayarak piroliz olarak seçilmiştir. Tüm prosesler için iki farklı sıcaklıkta enerji ve ekserji analizleri yapılmıştır. Modelden elde edilen sonuçlar, piroliz enerji veriminin 500֯ C ve 900֯ C'de %60 ve %94 olarak hesaplandığını göstermektedir. Sıcaklık değişiminin enerji ve ekserji verimi üzerindeki etkileri raporlanmaktadır.
