... interaction will be encountered if coal is processed with biochar that contains a limited amount of volatiles due to charring process. In this article, the existence of synergy was questioned based on the thermal analysis data obtained from the co-combustion of several biochars and lignite. The biochars...

...Melek Yilgin; Bedriye Hoş; Dursun Pehlivan In this study, torrefaction of pellets formed from furniture work dusts collected as a part of space cleaning actions in the industry has been examined. Burning behavior of torrefied dusts and lignite blends was studied. Torrefaction experiments were done...

... and lignite coal were co-pyrolyzed either in an inert carrier gas (N 2 ) or in oxidative gases consisting of 3–7% O 2 and 13–17% CO 2 in a balance of 80% N 2 . The process occurred at temperatures in the range of 300–900 °C, under 1 atm, and lasted for 20 min. The results showed that the solid-phase...

... enrichment and temperature on burnout levels. The oxygen-enriched air combustion performance of two Turkish lignites with different geological ages (early Miocene-Pliocene period Kutahya-Tuncbilek (KT) lignite and Pleistocene period Adiyaman-Golbasi (AG) lignite) was investigated in a horizontal tube reactor...

...A. Caliskan Sarikaya; H. Haykiri Acma; S. Yaman Woody biomasses such as ash tree (AT), hybrid poplar (HP), and rhododendron (RD) were subjected to torrefaction and carbonization at temperatures of 200 °C and 400 °C. Likewise, several lignite samples were carbonized at 750 °C. Various binary fuel...
