Simple but reliable methods for the determination of the physicochemical properties of gari were evaluated for the parameters, such as grain size, bulk density, swelling index, moisture content, gross calorific value, cyanide content, and acidity content. The grain sizes were between 525 and 928 μm (weighted means), the bulk densities between 0.541 and 0.699 g/cm³, and the swelling indices betw...

The natural gas quality fluctuates in complex pipeline networks, because of the influence transmission process, changes source, and fluctuations customer demand mixing process. Based on dynamic characteristics system with large time lag non−linearity, this article establishes a deep−learning−based prediction model for calorific value which is used to accurately efficiently analyze networks caus...

Solid waste management is challenging in Phnom Penh city, Capital of Cambodia. The only one formal treatment taken is the final disposal of mixed waste into an open dumpsite. The current study analyses the physical and chemical characteristics of municipal solid waste disposed of in the dumpsite to assess their suitable handling methods. The current study found that the major compositions of wa...

Waste Low density polyethylenes (LDPE) represent a source of energy and valuablechemicals, were pyrolysed catalytically in a batch reactor under atmospheric pressure. Calciumcarbide was used as a catalyst to explore its effect on pyrolysis product distribution. The effect oftemperature, amount of catalyst and time on the yields of the pyrolysed products wasinvestigated. The effect of catalyst o...
