Metal–Organic Frameworks for Separations

Dielectric-barrier discharges (silent discharges) are used on a large industrial scale. They combine the advantages of non-equilibrium plasma properties with the ease of atmospheric-pressure operation. A prominent feature is the simple scalability from small laboratory reactors to large industrial installations with megawatt input powers. Efficient and cost-effective all-solid-state power supplies are available. The preferred frequency range lies between 1 kHz and 10 MHz, the preferred pressure range between 10 kPa and 500 kPa. Industrial applications include ozone generation, pollution control, surface treatment, high power CO2 lasers, ultraviolet excimer lamps, excimer based mercury-free fluorescent lamps, and flat large-area plasma displays. Depending on the application and the operating conditions the discharge can have pronounced filamentary structure or fairly diffuse appearance. History, discharge physics, and plasma chemistry of dielectric-barrier discharges and their applications are discussed in detail.

An overview of hydrogen production technologies

Renewable technologies are considered as clean sources of energy and optimal use of these resources minimize environmental impacts, produce minimum secondary wastes and are sustainable based on current and future economic and social societal needs. Sun is the source of all energies. The primary forms of solar energy are heat and light. Sunlight and heat are transformed and absorbed by the environment in a multitude of ways. Some of these transformations result in renewable energy flows such as biomass and wind energy. Renewable energy technologies provide an excellent opportunity for mitigation of greenhouse gas emission and reducing global warming through substituting conventional energy sources. In this article a review has been done on scope of CO2 mitigation through solar cooker, water heater, dryer, biofuel, improved cookstoves and by hydrogen.

Role of renewable energy sources in environmental protection: A review

Catalysis for the valorization of exhaust carbon: from CO2 to chemicals, materials, and fuels. technological use of CO2.

A method of transforming a normally gaseous composition consisting essentially of methane into a material comprising a major portion, at least, of hydrocarbons containing at least two carbon atoms; the method comprising the steps of feeding the composition into a reactor including a first electrode means (2), a second electrode means (3) and at least one layer (4) of a normally solid dielectric material positioned between the first and the second electrode means; submitting the composition within the reactor in the presence of a normally solid catalyst (6) to a dielectric barrier discharge; and controlling the dielectric barrier discharge to convert the normally gaseous composition into the material comprising a major portion, at least, of the hydrocarbons containing at least two carbon atoms.

PROBLEM TO BE SOLVED: To provide a method for co-generating electricity and product flow containing at least one formally-liquid hydrocarbon. SOLUTION: An electric power generating system is operated by burning a first part of a composition which is gaseous under normal conditions containing methane. At least part of the electricity is used for operating a dielectric barrier discharge reactor having at least one of a first electrode device, a second electrode device, and a layer of a normally-solid dielectric material positioned between the first electrode device and the second electrode device. The second part of the composition is introduced into the reactor. The second part of the composition is subjected to dielectric barrier discharge in the presence of a normally-solid catalyst. The second part of the composition is turned to a product flow containing at least one normally-liquid hydrocarbon.
