Abstract The increase in the prices and demand for cooking fuel has necessitated deployment of an alternative (biomass wastes), which is efficient relatively inexpensive. Biomass wastes are abundant underutilized energy purposes Nigeria. conversion these into briquettes can help to mitigate over-dependency wood deforestation. In this study, biomass such as rice husks (RH), banana peels (BP), co...

This study aimed to maximize the utilization of date palm residues and convert them into an environmentally friendly form fuel. The variety Khalas (leaf fronds whole fronds) were used produce fuel briquettes at three moisture contents (8, 10, 12%) four storage times (0, 15, 30, 45 days). mechanical, fuel, quality properties these investigated. results showed that leaf had best in terms mechanic...

Oil shale is an important unconventional oil and gas resource, but it poorly utilized in the Dalianhe coal mining area, northeastern China. Systematic sampling test analysis were used to evaluate characteristics of quality. The research shows that between middle lower seams coal-bearing member a rich ore with high content, medium calorific value, ash volatile low moisture, ultralow sulfur conte...

Dioclea reflexa seeds belonging to the family called Fabaceae were evaluated for its oil content and fatty acid composition chemical composition. Proximate results indicated that D. reflexa seeds contained ash (9.17±0.01%), crude fat (10.65±0.01%), fiber (9.25±0.03%), moisture (13.30±0.01%), crude protein (26.00±0.43%), carbohydrate (31.63±0.12%) and calorific value (1372.07 KJ/100g. Minerals a...

It is well-known that the calorific value and heat transfer speed of coal are closely related to quality index, affect explosion intensity maximum pressure dust explosion. In this paper, for different indexes studied experimentally, main parameters affecting elucidated by principal component analysis multivariate statistical analysis.
