Thermal Dissolution of Bituminous Coal in Heavy Coal Semicoking Tar and in Binary Blends with the Anthracene Oil

The effect of hydrorefining of heavy coal semicoking tar on its composition and efficiency for bituminous coal dissolution was studied. It was found that the concentration of the oxygen-bearing compounds decreased as a result of catalytic hydrotreating with hydrogen or with hydrogen donors. This resulted in improved dissolving power. However, best result in coal dissolution was achieved when heavy semicoking tar was blended with the anthracene oil. The products obtained represented at ambient temperature solid pitch-like matter with the softening points of 124 to 138 °С (“ring and ball” method). It was composed of mainly bi- and three-cyclic aromatics, the content of quinoline-insolubles being less than 6 %, and the ash content less than 0.5 %

Study was conducted to identify the changes in nutritional and microbiological aspects of fresh, smoked, salt-smoke-dried (SSD: treated with salt, smoke and sunlight), Control dried (CD: treated only with sunlight) tengra (Mystus tengara) during storage at ambient temperature (26-28oC) and refrigeration temperature (40C). The study was done to investigate the effect of natural preservatives salt and smoke on the shelf life of the product over the storage period. The moisture content of fresh tengra was 76.06% whereas 18.80 and 18.36% for SSD and CD respectively. Fresh tengra had 13.45% protein, 7.46% lipid and 2.80% ash. The initial value of protein, fat and ash content of SSD tengra was 63.40, 19.95 and 16.55% respectively on dry matter basis. During 60 days storage period moisture increased whereas protein, fat, and ash content decreased considerably. After two month storage at ambient temperature the protein, lipid and ash content for SSD tengra were 62.75, 19.07 and 15.99% respectively whereas the values of the same parameters stored at refrigeration temperature were 62.54, 19.54 and 16.12% respectively on dry matter basis. The initial TVB-N and SPC value for SSD tengra was 5.86 mg/100g and 1.02×104 CFU/g respectively. During storage period the TVB-N and SPC value slowly increased and the values reached to 18.21 mg/100g and 3.32×104 CFU/g respectively for salt-smokedried tengra stored at ambient condition whereas 11.81mg/100g and 2.14×104 CFU/g respectively for the products stored at refrigeration temperature. The overall quality of salt-smoke-dried product was better than control dried product on the basis of organoleptic, nutritional and microbial aspects. Information obtained from this study it is cleared that, combination of salting, smoking and drying is efficient method of fish processing which could be useful to consumers, processors, and nutritionist at national and global basis.Asian J.

Objective: Thermal Dissolution (TD) and Co-thermal Dissolution (CTD) of Shenfu (SF) coal and lignin were studied. The effect of temperature on the TD and CTD of SF coal and lignin was discussed. Method: The synergistic effect of SF coal and lignin in CTD was probed with the characterization of thermal dissolution soluble fraction by elementary analysis, FTIR and TG determinations. Result: The results suggested that TD activity of lignin was higher than that of SF coal. Both SF coal and lignin gave their maximal thermal dissolution yield (TDY) of 57.6 and 82.5%, respectively at 360oC. In CTD of SF coal and lignin process, the experimental values (expressed by EXP) of TDY and Thermal Dissolution Soluble Yield (TSY) were both higher than the corresponding calculated weighted mean values (expressed by CAL) of TDY and TSY obtained from the individual TD of SF coal and lignin, suggesting that there existed a synergistic effect in the CTD of SF coal and lignin. Both TDY and TSY in CTD were enhanced to maximal values at 360oC with (EXP-CAL) values of 3.4 and 7.5%, respectively. Conclusion: There were interactions between SF coal and lignin in the CTD process. The pyrolysis of lignin at low temperature may form some intermediates such as phenoxy radicals, and these intermediates can further cause depolymerization of coal, thus promoting the TD of coal.
