Carbon adsorbents based on myanmar plant wastes as cleaning agent of industrial emissions and discharges

Abstract

In numerous productions of the Republic of the Union of Myanmar burdensome large-amount of
plant waste is formed. Sources of scientific and technical information indicate the principal possibility of
obtaining of activated carbon on their base, suitable for solving the problems of cleaning and neutralization
of a wide range of discharges and emissions of various enterprises and industries. The purpose of the study is
to evaluate in solving these problems the feasibility and effectiveness of using carbon adsorbents, obtained by
pyrolysis of representative samples of these wastes of national production (in the form of fragments of coconut
shells and plum seeds, Burmese iron-wood, mango seed shells, Guza-Pai – field residues of cultivation of
cotton and rice husks) and the steam activation of its carbonized material, as the most simple and affordable
technology for implementation in condition of Myanmar. The optimal conditions for the implementation of
these operations and technical parameters (yield, porous structure, absorption capacity, specific consumption
of steam, bulk density, abrasion resistance) of the obtained adsorbents are characterized. Characterizations of
the scientific novelty of the studying results of comparative evaluation of the effectiveness of their use in
solving the problems of multicomponent wastewater treatment (for example, wastewater release № 1 JSC
«Moskoks») and recuperation of vapors of volatile organic solvents (for example, n-butanol) from their mix tures with air are presented. It is stated that for a number of parameter (yield, porosity, absorption capacity
and other characteristics), not all of the obtained activated carbons reach the level of the best adsorbents on
the base of the corresponding similar waste, but can be competitive products in the organization of their production
in Myanmar, practically without enterprises of this profile, but experiencing significant needs in their
products, poorly satisfied due to the significant market price of activated carbon.
