Pyrolysis kinetics of blends of Tunçbilek lignite with Denizli peat

Pyrolysis of solid fuels: Thermochemical behaviour, kinetics and compensation effect

“…Obtained kinetic parameters were close to values reported in the literature for e.g. Turkish lignites (E: 14.6-44.7 kJ mol -1 , k 0 : 2.17 × 10 -1 -5.96 × 10 1 s -1 )[47,48], willow (E: 68.8-74.6 kJ mol -1 , k 0 : 3.51 × 10 3 -1.50 × 10 4 s -1 )[49] and coals (E: 73.6-127.5 kJ mol -1 , k 0 :…”

Pyrolysis by thermogravimetric analysis of blends of peat with coals of different characteristics and biomass

“…Accordingly, the À250 mm samples (Vamvuka et al, 2003) weighing about 20 mg (Güldogan et al, 1999) were subjected to a thermogravimetric analyses. Fig.…”

“…The kinetic analysis in the thermal decomposition is the most important tool in the study of the complex pyrolysis mechanism (Caballero et al, 1997). In several publications it has been reported that weight loss occurs in relation to a constant increase in temperature and kinetic analysis is used in thermal analysis processes, such as pyrolysis of coal, biomass or blends of these (Biagini et al, 2002;Cozzani et al, 1995;Güldogan et al, 1999;Helsen and Van den Bulck, 2000;Jones et al, 2005;Kastanaki et al, 2002;Klose and Stuke, 1993;Koufopanos et al, 1989;Meesri and Moghtaderi, 2002;Nassar, 1999;Pan et al, 1996;Raveendran et al, 1996;Vamvuka et al, 2003Vamvuka et al, , 2006Vuthaluru, 2004a).…”

Peat semicoking and hydrocracking

“…Peat carbonizing yielded brittle highly reactive cokes [2]. The regularities of peat pyrolysis in blends with coals, lignite and biomass have been studied as well [25,26]. As a rule, the higher the value of H/C in the feed, the higher the yield of the soluble product.…”
