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