combined cycle performance can be improved by improving the performance of gas turbine based topping cycle. amongst various options the effective cooling of gas turbine blade for realizing the higher turbine inlet temperatures is one of the attractive options. the present paper deals with the thermodynam-ic analysis of advanced technology gas/steam combined cycle based power plant having closed...

The biogas needs to be reformed before electro-chemical conversion in the solid-oxide fuel cell, which can promoted efficiently with wise thermal management and reforming conditions. To ensure system safety catalysts durability, additional mineral-bearing water carbon deposition should avoided. This paper conducted a detailed biogas-SOFC CHP analysis considering four layouts, featuring hot cold...

In this paper, an integrated coke dry quenching combined gasification system using coke oven gas and steam to quench the incandescent coke is proposed. The distinct advantages of the system include energy conservation, pollution reduction, coke quality improvement and full use of resources. Based on the minimization of the Gibbs free energy, the flow rate and composition of the syngas are predi...

In this idealized, stoichiometric equation, cellulose (represented as C,H,,O,) reacts with water to produce hydrogen and carbon dioxide, mimicking the commercial manufacture of hydrogen from methane by catalytic steam reforming chemistv. More realistically, a practical technology must be able to convert the cellulose, hemicellulose, lignin, and extractive components of the biomass feedstock to ...

The partial oxidation and CO2 reforming of methane were studied on Pt/Al2O3, Pt/ZrO2, and Pt/ Ce–ZrO2 catalysts. The reducibility and the oxygen transfer capacity were evaluated by oxygen storage capacity (OSC). The effect of the support on the cleaning mechanism of the catalyst surface was investigated by the sequence of CH4/O2 and CH4/CO2 pulses. The Pt/Ce–ZrO2 catalyst showed the highest sta...

2. Productivity at this level means that the production costs of H 2 (expressed as the cost in US dollars per joule of calorific value contained in the molecule) are two to three times higher than for natural gas 4,5. However, taking into account the transportation and distribution costs of natural gas, and how pure you want the H 2 to be, the comparative cost of H 2 production can vary. Biomas...

this study was conducted to compare fungi and whole rumen microorganisms (wrm) digestibility of treated sugarcane pith by fungi and of buffalos and holstein cows. dry matter (dm), neutral and acid detergent fiber (ndf and adf) digestibilities of steam treated sugarcane pith (stp) by fungi and wrm were compared with a two-steps digestion technique, gas production (gp) and specific rumen fungi cu...

Renewable hydrogen may be produced in the near term at a cost that is competitive with natural gas reforming by integrating hydrogen production with existing industrial utilization of agricultural residues. A team of government, industrial, and academic organizations is developing a steam reforming process to be demonstrated on the gaseous byproducts from a process for making activated carbon f...

A micro-channel heat exchanger reactor with different micro-baffle shapes has been studied numerically. Governing equations were solved base on the finite volume method with FLUENT software. In upper section, oxidation reaction of methanol was occurred and in lower section, steam reforming of methanol was done. Two sections were separated with solid part which played as heat exchanger and trans...
