Producing Mereells with enhanced surface activity

Producing Mereells with enhanced surface activity through alkaline pretreatment of feedstocks.,reebok reignman 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 ,zappos mens 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,reebok zigtech basketball shoes, condensed macromolecular structure,skechers men shape ups, Mereell is chemically and biologically more stable than its original carbon sources.
This makes Mereell difficult to breakdown,skechers shape ups sleek fit, remaining stable in soils potentially for hundreds to thousands of years. Because of the stability of Mereell against chemical and biological degradation,reebok zig running shoes, 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 women's shape ups xf size 5.5, final temperature,reebok tennis shoes, residence time,mens reebok 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,women's reebok simply tone shoes, such as carbon dioxide or water steam,skechers shape ups for men, while chemical activation involves the use of inorganic chemicals,reebok zigtech shoes white and black, such as zinc chloride,reebok zig pulse shoes, phosphoric acid,reebok zigzag running shoes wearing out on the side, and potassium or sodium hydroxides . Sodium hydroxide has been reported to promote a better activation of lignocellulosic materials than potassium hydroxide,reebok women's aerobic shoes, and this occurs predominantly via a non-intercalation mechanism in the former and through an intercalation process in the latter .
