This work investigates the potential of coconut shell for air-steam gasification using thermodynamic equilibrium model. A thermodynamic equilibrium model considering tar and realistic char conversion was developed using MATLAB software to predict the product gas composition. After comparing it with experimental results the prediction capability of the model is enhanced by multiplying equilibriu...

This work aimed to investigate the impact of highest treatment temperature (HTT), heating rate, carrier gas flow rate and feedstock on the composition and energy content of pyrolysis gas to assess whether a self-sustained system could be achieved through the combustion of the gas fraction alone, leaving other co-products available for alternative high-value uses. Calculations based on gas compo...

abstract- in this study, texture profile analysis and a creep test were used to determine the textural quality attributes of fish protein isolates and conventional surimi. these isolates were made from raw materials obtained from filleting processes of silver carp (hypophthalmichthys molitrix) using acid and alkaline aided treatments. texture profile analysis was performed in order to obtain ha...

We derive self-similar solutions including cooling and heating in an Einstein de-Sitter universe, and investigate the effects of cooling and heating on the gas density and temperature distributions. We assume that the cooling rate has a power-law dependence on the gas density and temperature, Λ∝ρT, and the heating rate is Γ∝ρT . The values of A and B are chosen by requiring that the cooling tim...

District heating pricing is a core element in reforming the heating market. Existing district heating pricing methods, such as the cost-plus pricing method and the conventional marginal-cost pricing method, cannot simultaneously provide both high efficiency and sufficient investment cost return. To solve this problem, the paper presents a new pricing model, namely Equivalent Marginal Cost Prici...

• A detailed LHV determination method with uncertainty quantification is reported. Determinations leverage a fundamental approach GC × GC-FID measured class concentrations. Uncertainty quantifications consider isomeric, GC, and heats of formation variance. All 17 determinations from this work agree ASTM D4809 measurements. The D3338 estimation agrees poorly for alternative fuels. assessment pre...

In design of a parallel resonant induction heating system, choosing a proper capacitancefor the resonant circuit is quite important. The capacitance affects the resonant frequency, outputpower, Q-factor, heating efficiency and power factor. In this paper, the role of equivalent seriesresistance (ESR) in the choice of capacitance is significantly recognized. Optimal value of resonancecapacitor i...
