Combustion behaviour of coal and biomass are different due to difference in their physical and chemical properties. Thermogravimetric analysis is a useful technique to determine combustion characteristics of coal/biomass blends. This study elaborates the lab scale findings of co-combustion experiments in Thermogravimetric analyzer (TGA) [in which Differential Scanning Calorimetric (DSC) and The...

Co-firing ramie residue with coal was carried out in a thermogravimetric analyzer and a cyclone furnace to evaluate the effects of coal fraction (0 to 30 wt. %) on combustion performance. Thermogravimetric analysis (TGA) results showed that devolatilisation was the predominant process when the coal percentage in the blend was below 30 wt. %. For pure biomass firing in the cyclone furnace, an op...

some innovative solutions are proposed to the problem of the unavoidable physical migration of antioxidants from plastic films for packaging, in order to minimize the consequent undesirable effect of food contamination. in previous exploratory tests, phenolic antioxidant co-units were achieved and incorporated into polyethylene chain and now the work is extended to create new families of polyme...

Polypyrrole–hydroxyethylcellulose/TitaniumDioxide (PPy-HEC/TiO2) nanocomposite was synthesized via in situ chemical oxidative polymerization method at room temperature in water and water/ethyl acetate solution in the presence of ferric chloride (FeCl3). The effect of TiO2 nanoparticles and HEC on the characteristics of products such as thermal stability and morphology was investigated. The fabr...

1. General experiments 2-(imidazol-1-yl)terephthalic acid (Im-H 2 BDC • HCl) was prepared by a similar process according to the literature. 1 Other reagents were purchased from commercial sources and used as received. N 2 and CO 2 sorption isotherms of Im-UiO-66 (1) and (I-)Meim-UiO-66 (2) were measured by using a Micrometrics ASAP 2420 instrument at 77 K and 273K, 298 K, respectively. Before t...

p-Chlorobenzophenone (p-CBP) is the important chemical intermediate used for the synthesis of several pharmaceutical drugs like fenofibrate, cetirizine, alprazolam, and benzodiazepine. The aim of this study was set to evaluate the impact of biofield energy treatment on physicochemical and spectroscopic properties of p-CBP. The study was accomplished in two groups i.e. control and treated. The t...
