The influence of torrefaction temperature and reaction time on the properties of torrefied sun‐dried millet and sorghum straws from the arid and semi‐arid zones of western Africa

Biofuels, Bioproducts and Biorefining, Volume 17, Issue 3, Page 751-767, May/June 2023., 2023
Abstract There are increasing demands for syngas production. Fossil‐based fuels are expensive and environmentally unfriendly. Affordable, sustainable, and environmentally healthy alternatives and sustainable fuel sources are needed. This study focused on producing tor‐chars from two different tropical biomasses (from Nigeria, West Africa), which were ...

Screening the Main Factors Affecting the Wear of the Scraper Conveyor Chute Using the Plackett–Burman Method

Mathematical Problems in Engineering, Volume 2019, Issue 1, 2019., 2019
The wear of scraper conveyor chute causes both significant economic and environmental losses by shortening the service life. The life of the chute under coal abrasive wear situations is primarily decided by operating conditions and the materials properties. The comprehensive analysis of the influence factors had not been studied before.

A Modified Model for Kinetic Analysis of Petroleum Coke

International Journal of Chemical Engineering, Volume 2019, Issue 1, 2019., 2019
In this study, a nonisothermal kinetics analysis of petcoke was performed at heating rates of 10, 15, and 20°C/min using thermal gravimetric analysis (TGA). The behaviour of petcoke at different gasification stages (dewatering, volatilization, char burning, and burnout) was studied.

Effects of Maceral Compositions of Coal on Methane Adsorption Heat

Geofluids, Volume 2018, Issue 1, 2018., 2018
The role of maceral compositions (vitrinite and inertinite) in the adsorption characteristics of coal has not been fully understood in terms of energy. In this study, using a microcalorimeter, the adsorption heat of maceral compositions for methane is directly measured for five groups of Chinese coal samples with different coal ranks.

Characterization of Some Nigerian Coals for Power Generation

Journal of Combustion, Volume 2016, Issue 1, 2016., 2016
Five coal samples from Odagbo (Kogi State), Owukpa (Benue State), Ezimo (Enugu State), Amansiodo (Enugu State), and Inyi (Enugu State) of Nigerian coal deposits were subjected to proximate analysis, ultimate analysis, calorific value determination, and petrographic and thermogravimetric analysis to determine their suitability for power generation ...

Physical Characteristics and Technology of Glass Foam from Waste Cathode Ray Tube Glass

Journal of Materials, Volume 2013, Issue 1, 2013., 2013
This paper deals with the laboratory investigation of cathode‐ray‐tube‐ (CRT‐) glass‐based glass foam, the so‐called “Geofil‐Bubbles” which can be applied in many fields, mainly in the construction industry (lightweight concrete aggregate, thermal and sound insulation, etc.).

Relationship between Particle Size Distribution of Low‐Rank Pulverized Coal and Power Plant Performance

Journal of Combustion, Volume 2012, Issue 1, 2012., 2012
The impact of particle size distribution (PSD) of pulverized, low rank high volatile content Alaska coal on combustion related power plant performance was studied in a series of field scale tests. Performance was gauged through efficiency (ratio of megawatt generated to energy consumed as coal), emissions (SO2, NOx, CO), and carbon content of ash (fly ...

Toward Fossil‐Free Steelmaking: Overview of Physiochemical Properties of Hydrochar and Its Application in Blast Furnace and Electric Arc Furnace Processes

cScience, Volume 1, Issue 1, December 2025.
ABSTRACT The steel industry is among one of the largest CO2 emitters in the world. To meet climate targets, replacing fossil‐based carbon with renewable biocarbon in metallurgical processes, particularly in blast furnaces (BFs) and electric arc furnaces (EAFs), has emerged as a viable short‐ to mid‐term solution.
