Co‐combustion of coal and biomass waste in pilot‐scale for energy use

open access: yesEnvironmental Progress &Sustainable Energy, Volume 44, Issue 3, May/June 2025.
Abstract The use of biomass in co‐combustion systems using fluidized bed technology is considered a viable alternative to reduce the emission of pollutants. The herein study presents an experimental analysis to determine the technical feasibility of using run‐of‐mine (ROM) coal and its waste combined with biomass in a combustor of bubbling fluidized ...

Low Temperature Synthesis of Li2SiO3: Effect on Its Morphological and Textural Properties

open access: yesAdvances in Materials Science and Engineering, Volume 2008, Issue 1, 2008., 2008
Synthesis, at low temperature, of Li2SiO3 was investigated using different Li : Si molar ratios and urea, which was used as template. This new synthesis was performed in order to look for different textural and morphological properties than those obtained usually by conventional methods in this kind of ceramics. XRD and SEM analyses showed that Li2SiO3

Automatic system for the determination of boron in ceramic frits

open access: yesJournal of Analytical Methods in Chemistry, Volume 13, Issue 3, Page 107-110, 1991., 1991
An automatic system for the potentiometric determination of boron in ceramic frits was developed. The system includes a personal computer for instrumental control, data acquisition and processing, which allows up to 13 samples to be analysed sequentially with no human intervention.
