Biyokütle ısı enerjisi elde etmek amacıyla doğrudan yakılarak kullanılabileceği gibi termokimyasal yöntemlerle piroliz, gazlaştırma, sıvılaştırma ve biyokimyasal anaerobik bozunma proseslerinden geçirilerek katı, sıvı ve/veya gaz ürün eldesi için de kullanılabilir. Biyokütleden enerji dönüşümünde gelecek vadeden termokimyasal dönüşüm yöntemlerinden birisi de gazlaştırma prosesidir. Ancak, biyokütle gazlaştırma prosesinde katran da meydana gelir.

Katran gideriminde son yıllarda gerçekleşen çalışmalar çerçevesinde, etkin bir yöntem olarak sunulan katalitik filtreler ile hem partikül hem de katran giderimi tek adımda gerçekleştirilebilmektedir. Partikül ve katran gideriminin yüksek sıcaklıkta ve tek adımda gerçekleştirilmesi de enerji verimliliği sağlamaktadır. Bu çalışmada, biyokütleden gazlaştırma yolu ile sentez gazı eldesinde kullanılan yüksek sıcaklıklarda çalışabilen gaz filtreleri ve filtreleme yöntemleri üzerine bir değerlendirme yapılmıştır.

The Evaluation of Gas Filters and Filtration Methods Used in the Production of Synthesis Gas from Biomass

Öz

Biomass can either be used directly by burning to obtain heat energy, or
can be converted into solid, liquid and / or gaseous products by thermochemical
methods such as pyrolysis, gasification, liquefaction and biochemical anaerobic
decomposition. The biomass gasification process is one of the promising options
among the thermochemical conversion methods. However, tar is also produced
during the gasification process.  

In recent studies regarding tar removal, both the particle and tar
removal can be accomplished in a single step with the catalytic filters as an
effective method. Particle and tar removal at high temperatures and in one step
ensures energy efficiency. In this study, an evaluation was made on gas
filters, which can operate at high temperatures, and filtration methods used in
the production of synthesis gas from biomass.
