Çan Linyitinin Sorgum Biyokütlesi İle Gazlaştırılmasında Biyokütle Oranı ve Sıcaklığın Etkisi

Çan linyiti ve sorgum biyokütlesi farklı oranlarda sorgum içerecek şekilde karıştırılarak, 700°C sıcaklıkta birlikte gazlaştırılmış ve karışımdaki sorgum oranının toplam gaz hacmi ile gaz ürün dağılımına etkileri incelenmiştir. Hem toplam gaz hacmi hem de üretilen hidrojen gazının miktarı açısından en etkin sorgum konsantrasyonu % 25 olarak belirlenmiştir. %25 sorgum içeren kömür/sorgum karışımı, 700, 800 ve 900 °C sıcaklıklarda gazlaştırılarak, sıcaklık artışının toplam gaz hacmi ve gaz ürün dağılımındaki etkileri incelenmiştir. En etkin gazlaştırma sıcaklığı 900 °C olarak belirlenmiştir. %25 sorgum içeren 1 gram kömür/sorgum karışımının 900 °C sıcaklıkta birlikte gazlaştırılmasından %71,4 hidrojen gazı içeren 2729 mL gaz elde edilmiştir.

The Effects of Biomass Ratio and Temperature on Co-Gasification of Çan Lignite with Sorghum Biomass

Co-gasification experiments of mixtures of Çan lignite and sorghum biomass containing different concentrations of sorghum were performed and the effects of biomass ratio in coal/biomass mixtures on total gas volumes and syngas product distributions were evaluated. The most effective sorghum concentration was determined as 25 %, in terms of both total gas volumes and hydrogen gas production volumes. he coal / sorghum mixture containing 25% sorghum was gasified at temperatures of 700, 800 and 900 ° C and the effects of temperature increase on total gas volume and gas product distribution were investigated. The most effective gasification temperature was determined as 900 ° C. 2729 mL of gas with 71.4% hydrogen gas was obtained by co-gasification of 1 gram of coal / sorghum mixture containing 25% sorghum at 900 ° C.
