TL;DR: The ASTM D7708: standard test method for microscopical determination of the reflectance of vitrinite dispersed in sedimentary rocks was published in 2012 as discussed by the authors, and an inter-laboratory exercise was conducted to establish precision limits for the D 7708 measurement.
Journal ArticleDOI
Comparison of chars obtained under oxy-fuel and conventional pulverized coal combustion atmospheres
Angeles G. Borrego,Diego Alvarez +1 more
TL;DR: In this article, two coals of different rank (a high volatile and a low volatile bituminous) have been burned in a drop tube reactor using O2/N2 and O2-CO2 mixtures with increasing oxygen content from 0 to 21%.
Journal ArticleDOI
Organic matter composition and distribution through the Aptian–Albian lacustrine sequences of the Araripe Basin, northeastern Brazil
TL;DR: In this paper, the main characteristics and distribution of organic matter have been studied through several Aptian-Albian lacustrine units (Rio da Batateira, Crato and Ipubi Formations, Araripe Basin, NE Brazil).
Journal ArticleDOI
Phase-mineral and chemical composition of coal fly ashes as a basis for their multicomponent utilization. 3. Characterization of magnetic and char concentrates
Stanislav V. Vassilev,Rosa Menéndez,Angeles G. Borrego,Mercedes Díaz-Somoano,M. Rosa Martínez-Tarazona +4 more
TL;DR: The phase-mineral and chemical composition of magnetic (MCs) and char concentrates recovered from five fly ashes (FAs) produced in four large Spanish thermo-electric power stations was characterized.
Journal ArticleDOI
Influence of pyrolysis temperature on char optical texture and reactivity
TL;DR: In this article, a set of 10 coals varying in rank and maceral composition has been devolatilised in a flat flame burner at 1000 and 1300°C in order to investigate the changes in char reactivity and structure as a function of pyrolysis temperature.
