Ash from thermal power plants as secondary raw material.
The basic characteristic of thermal power plants in the Republic of Serbia is that they use low-grade brown coal (lignite) as a fuel. Depending on the location of coal mines, lignite may have different properties such as heating value, moisture, and mineral content, resulting in different residue upon combustion. Because of several million tonnes of ash and slag generated every year, their gran...
متن کاملObtaining raw material: plants as tool sources for Nigerian chimpanzees.
We investigated the acquisition of plant materials from which Nigerian chimpanzees manufacture wooden tools to harvest insects and honey from nests of army ants, honey bees and stingless bees. Slender trunks of juvenile trees and branches are most commonly used, and bendable vines rarely, probably reflecting the need to work with relatively sturdy tools to extract resources. While several tools...

متن کاملGrass Species as Raw Material for Pulp and Paper
Paper has been made from grasses and other non-wood materials for over 1900 years. Wood is a relatively new papermaking fibre, only 100 years old. Today the commercial non-wood pulp production accounts for 6% of the global pulp production. The main source for the raw material is plants of the Gramineae family. Research on nonwood material has concentrated on grasses like Miscanthus, Phalaris, S...
متن کاملReductive de-polymerization of kraft lignin for chemicals and fuels using formic acid as an in-situ hydrogen source.
In this study, formic acid (FA) was employed as an in-situ hydrogen donor for the reductive de-polymerization of kraft lignin (KL). Under the optimum operating conditions, i.e., 300 °C, 1 h, 18.6 wt.% substrate concentration, 50/50 (v/v) water-ethanol medium with FA at a FA-to-lignin mass ratio of 0.7, KL (Mw∼10,000 g/mol) was effectively de-polymerized, producing de-polymerized lignin (DL, Mw ...
