Our goal in this paper is the description and analysis of new findings and results on membrane reactors and catalytic reactors/heterogeneous processors for the steam reforming reactions of methane, natural gas, and methanol for use in power generation systems and fuel cells. The current communication continues this research by giving emphasis in the so-called “Improved Reaction” and “ReformingF...

BACKGROUND Biogas is a renewable energy carrier which is used for heat and power production or, in the form of purified methane, as a vehicle fuel. The formation of methane from organic materials is carried out by a mixed microbial community under anaerobic conditions. However, details about the microbes involved and their function are limited. In this study we compare the metagenomes of four p...

The current situation and possible future developments for nuclear power--including fission and fusion processes--is presented. The fission nuclear power continues to be an essential part of the low-carbon electricity generation in the world for decades to come. There are breakthrough possibilities in the development of new generation nuclear reactors where the life-time of the nuclear waste ca...

In present day's energy conveyance frameworks is experiencing serious force quality issues. These force quality issues incorporate high responsive force trouble, music momentums, burden unbalance, unreasonable unbiased current and so forth. A few solutions for these force quality issues are accounted for in the writing. A gathering of controllers together called Custom Power Devices (CPD), whic...

A set of constraints is derived for the operating characteristics of tokamak power reactors which are bulk heated by electron cyclotron resonance heating (ECRH). Four heating modes are considered: ordinary wave heating at the electron cyclotron frequency, 0, and at the second harmonic frequency, 20, and extraordinary wave heating at 0 and at 20. For ordinary wave heating at 1, which appears to ...

Microbial fuel cells (MFCs) are devices that exploit living microbes for electricity generation coupled to organics degradation. MFCs are expected to be applied to energy-saving wastewater treatment (WWT) as alternatives to activated-sludge reactors (ASRs). Although extensive laboratory studies have been performed to develop technologies for WWT-MFCs, limited information is available for compar...

For meaningful assessment of results from laboratory and pilot plant trials, it is often necessary to know the mixing characteristics within the ultrasonic reactors. Previous workers have used conductivity measurements in an attempt to characterize the residence time distribution in ultrasonic reactors, but these results do not provide direct data on the mixing within the high power region adja...
