Producing Mereells with enhanced surface activity through alkaline pretreatment of feedstocks.,skechers women's shape ups
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 ,reebok mens basketball shoes, 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,black reebok work shift shoes, condensed macromolecular structure,reebok zig tech shoes, Mereell is chemically and biologically more stable than its original carbon sources.
This makes Mereell difficult to breakdown,skechers shape ups for men, remaining stable in soils potentially for hundreds to thousands of years. Because of the stability of Mereell against chemical and biological degradation,reebok zig shoes youth, its production represents a promising technology for mitigating greenhouse gas emissions . Process conditions that most affect Mereell properties during pyrolysis are the heating rate,skechers shape ups strength, final temperature,reebok zig tech shoes, residence time,reebok zigtech shoes white and black, 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,skechers shape ups in ireland, such as carbon dioxide or water steam,skechers shape ups optizime wide, while chemical activation involves the use of inorganic chemicals,reebok zig pulse ii running shoes, such as zinc chloride,skechers shape ups originals, phosphoric acid,reebok zigtech shoes, and potassium or sodium hydroxides . Sodium hydroxide has been reported to promote a better activation of lignocellulosic materials than potassium hydroxide,reebok zig energy mens shoes, and this occurs predominantly via a non-intercalation mechanism in the former and through an intercalation process in the latter .
