Activated Carbon Can be Used for CH4 Storage and Transportation
Stored
natural gas plays a vital role in ensuring that any excess supply delivered
during the summer months is available to meet the increased demand of the
winter months. However, with the recent trend towards natural gas fired
electric generation, demand for natural gas during the summer months is now
increasing (due to the demand for electricity to power air conditioners and the
like). At the time, the natural gas industry noted that seasonal demand
increases could not feasibly be met by pipeline delivery alone. Natural gas in
storage also serves as insurance against any unforeseen accidents, political
conflicts, natural disasters, or other occurrences that may affect the
production or delivery of natural gas. In order to be able to meet seasonal
demand increases, underground storage fields were the only option. Before the
storage process, transportation takes places an important role. Scientists
developed an option for gas storage and economical method for transportation of
natural gas by the help of active carbon’s adsorption property. Via the high adsorption rate and capacity of
activated carbon, the higher mole of methane, can be possible to store at
low pressures by comparison with conventional methods.
Adsorption
is the process by which molecules of a substance, such as a gas or a liquid,
collect on the surface of another substance, such as a solid. The molecules are
attracted to the surface but do not enter the solid's minute spaces as in
absorption.
Activated
carbon is a form of carbon processed to be riddled with small, low-volume pores
that increase the surface area available for adsorption or chemical reactions.
Activated carbon is a carbonaceous adsorbent with a high internal porosity, and
hence a large internal surface area. Commercial activated carbon
grades have an internal surface area of 500 up to 1500 m2/g. People studied
the feasibility of storing CH4 in an abandoned coal mine and transportation of
CH4 by tankers in adsorbed state using activated carbon as medium. It can be
concluded that active carbon can be used for safe storage and transportation of
methane as an alternative to conventional methods.
Now, we need
to use good performance active carbons that help people to transport as much
CH4 as possible in one time. Problem is how to know that very active carbon is
suitable for us. Under this situation, we need one instrument to help us, to
analysis that active carbon adsorption performance, and that instrument is HIGH PRESSURE GAS SORPTION ANALYZER.
We, Gold APP Instruments, had researched and produced high pressure gas sorption analyzer H-Sorb
2600 series by static
volumetric principle. Capable of testing nanomaterials adsorption and desorption
performance, PCT (pressure composition temperature) or PCI (pressure
composition isotherm) curves. H-Sorb 2600 series with 2 analysis ports and 2 degassing ports,
fully automated operation, supports night operation without operators watch,
longest supporting test time can be last as long as half month (can be
upgrade), all-featured data reports can help researchers to get all analysis
details they want.
Gold APP
Instruments China is a
professional manufacturer for analytical and research instruments, such as BET surface area analyzers, surface area and porosity analyzers, helium true density analyzers, high pressure gas sorption analyzers and so on, to determine nanomaterials
specific surface area, pore size, pore volume, pore size distribution, true
density, open and closed spaces, adsorption/desorption isotherms,
pressure-composition-isotherm, pressure-composition-temperature curve and so
on.
