Low-carbon means the low or lower emission of greenhouse gas(primarily carbon dioxide). With the development of globle industrial economy, increasing of population, inflation of human desire and incontinence of the way of life and production, the world climate has been confronted with more and more difficult problems. The emission of carbon dioxide has been increasing and the ozone layer has been suffering from an unprecedented crisis. Climate change of globle catastrophic has appeared repeatedly and has serious harm to human's survival environment and safety of health. Although humans are pround of GDP for its growth or inflation in high speed, GDP knocks off for the pollution of environment and climate change (therefore, countries appeale to the development model and statistical way of "green GDP").

Introduction of low-carbon

Physical Description: Carbon compounds generally refers to the products out of fossil fuels, which are seperated and further synthesised into those necessary for life and production, such as ethylene, plastic, etc.

The forms of carbon are varied, including crystallized elemental carbon, such as diamond and graphite; amorphous carbon, such as coal; complex organic compounds, such as flora and fauna; carbonate, such as marble, etc. physical and chemical properties of elemental carbon depend on its crystal structure. The crystal structure of diamond with high hardness is different from that of graphite with soft oiliness in appearance, density, melting point, etc.

Elemental carbon at normal temperature is not lively and insoluble in water, dilute acid, dilute alkali and organic solvent; the reaction with oxygen at different high temperature can produce carbon dioxide or carbon monoxide; among halogen, only fluorine can react directly with elemental carbon; with heat, elemental carbon is easy to be oxidized by acid; at high temperature, carbon also can react with large amounts of metal to produce metal carbide. Due to the reducibility of carbon, it can be smelted into metal at high temperature. the so called low-carbon life refers to the life that decreases the energy consumed in one's life to the minimum, as a result of reducation of carbon emission.

Chemical Element

Use of Charcoal

Charcoal is the material, which is important and indispensable for the national economy. Charcoal used to be as fuel. As charcoal is flammable, fire resistant, with less ash and no sulfur, it has been a kind of high quality fuel.

Due to its unique microporous structure and strong adsorption ability, charcoal has been widely used in food, pharmaceutical, chemical, metallurgy, national defense, agriculture and environmental protection, etc.
