Among the efficient adsorbents, carbon materials are quite promising due to their wide range of porosity, high surface area and low cost.
Carbon aerogels are novel porous carbon materials that have received considerable attention in the literature over the past decade or so.
The major uptake at relative pressures less than 0.1 and an almost horizontal plateau at higher relative pressures indicate they are highly microporous materials.

The biogas is obtained from organic materials decomposition; mainly the methane has energetic potential, especially for the combustion process in internal combustion engines.
The development of this sector is confronted with its competition with the food processor in semi-arid countries like Algeria, which limits its potential to respond to national energy demands to the use of various waste materials in order to produce biofuels.

Siphoning has long been recognised as the most loss efficient method of metal transfer and now with the availability of fully engineered, automated systems which are safe and reliable in addition to reducing melt loss by 75%; this method is set to become the industry standard.
The net loss of aluminium in this conversion is counted as an energy loss (as well as a material loss, due to its irreversible nature) by accounting for the cumulative energy consumed in producing the aluminium from bauxite.
The success of this system encouraged the installation of a system which married the Comalco developed siphon automation to a specially engineered pipe handling system designed by Major Furnace Australia for the third potline expansion at the Boyne Smelter, Queensland.
(CRUCIBLE WEI POIN SIPHO PIP META FLOW (CRUCIBLE WEI POIN SIPHO PIP META FLOW SUCTIO (HOLDING The key functional parts of the system are: the siphon pipe handling & pre-heating system; the siphon vacuum control system; the operator interface; pipe transport and maintenance equipment and the furnace interlocks.
It is clear from the data presented that filling a holding furnace with molten aluminium is no longer the 'tall poppy' of energy wastage when siphoning is employed and now with the availability of fully engineered, automated systems, this method is set to become the industry standard.

Generally speaking, the wettability is different with different roller materials, leading to different conditions between roller and strip.
