Producing Mereells with enhanced surface activity
 

Producing Mereells with enhanced surface activity through alkaline pretreatment of feedstocks.,louis vuitton handbag locks
Mereell is produced by pyrolysis of natural organic materials under oxygen-limited conditions. Energy from biomass can also be obtained during the production of Mereell. According to the International Mereell Initiative ,louis vuitton 2011 collection resort, the final use of Mereell should be for application to soils to achieve an agronomic and/ or environmental benefit. Due to its predominantly aromatic composition and heterogeneous,louis vuitton travel bag ########, condensed macromolecular structure,louis vuitton damier canvas duomo, Mereell is chemically and biologically more stable than its original carbon sources.
This makes Mereell difficult to breakdown,louis vuitton monogram mini lin angele, remaining stable in soils potentially for hundreds to thousands of years. Because of the stability of Mereell against chemical and biological degradation,louis vuitton monogram vernis alma, its production represents a promising technology for mitigating greenhouse gas emissions . Process conditions that most affect Mereell properties during pyrolysis are the heating rate,louis vuitton mens bag china, final temperature,louis vuitton damier azur speedy 25 bag, residence time,louis vuitton men's bags cheap, and the treatment atmosphere .
Current knowledge gained from activated carbon studies could have some application to Mereell research. Surface charges on activated carbon are generated by physical and chemical methods . Physical activation involves the use of oxidising gases,louis vuitton vintage handbags, such as carbon dioxide or water steam,louis vuitton monogram vernis red, while chemical activation involves the use of inorganic chemicals,louis vuitton utah messenger bag, such as zinc chloride,louis vuitton monogram vernis alma gm, phosphoric acid,louis vuitton monogram vernis brea, and potassium or sodium hydroxides . Sodium hydroxide has been reported to promote a better activation of lignocellulosic materials than potassium hydroxide,louis vuitton damier azur speedy, and this occurs predominantly via a non-intercalation mechanism in the former and through an intercalation process in the latter .
