Carbon Clothing Essay

1736 words - 7 pages

Carbon is a simple element on the periodic table. Carbon is found in all living things. There is also another role that this element plays apart of and that is hunting. I bet you probably didn’t know that until now, but they have activated carbon clothing for scent elimination. There are also other uses for them but we’ll go over that later on.

Activated carbon works through the process of physical adsorption, similar to a sponge only with air instead of water. In the fabric of clothing the carbon creates a bond that traps odor molecules produced by the body. Activated carbon acts like microscopic Velcro. When the odor molecules come into contact with the activated carbon, they are ...view middle of the document...

Thanks to the characteristic of reduced diffusion resistance during the process of adsorption and desorption, ACF has much greater capacity and higher speed in performing adsorption and desorption than powders and granules. Another advantage of ACF is its easy-forming property that can be fabricated into cloth, felt, and paper to meet different demands in application. This new and advanced material is the answer to demands for improved military and industrial protection. ACF, in fabric, out performs Granular Activated Carbon (GAC) and Powdered Activated Carbon (PAC) in the respect of formation. With the help of corrugation and sewing technology, it can be made into whatever forms to meet any unique requirement in applications. ACF effectively removes aliphatic, hydrocarbons, halogenated, aromatic, aldehydes, ketoses, acids, alcohols, phosphorus compounds, ethers, esters, sulfur, and nitrogen compounds. ACF also removes hydrogen sulfide, sulfur dioxide, chloride, and formaldehyde.
The advantages of ACF include huge adsorption volume, heat-resistance, acid-proof, and base-proof. ACF’s capacity for adsorption of organic vapors, such as gasoline, aldehydes, alcohols, and phenol, is seven to ten times that of GAC. It also has significant capability in adsorbing inorganic gas (e.g. NO, NO2, SO2, H2S, HF, HCl etc.) as well as substances in water solution (e.g. dyes, COD, BOD, oils, metal ions, precious metal ions). It also exhibits outstanding ability in the adsorption of bacteria. A bed of 3mm to 4mm thickness of ACF can have similar adsorption performance as a bed of 20mm to 100mm thickness of GAC. ACF does not only perform remarkably for high concentration substances but also for low concentration. For instance, ACF adsorbs toluene when the gas concentration is diminished to 100ppm, whereas GAC starts to absorb only when the concentration is more than 100ppm. Furthermore, ACF performs normal adsorption even if the concentration of phenol in wastewater is lowed down to 5ppm to 10ppm, which is not achievable by other adsorption materials.
Extruded activated carbon (EAC) combines powdered activated carbon with a binder, which are fused together and extruded into a cylindrical shaped carbon block with diameters from 0.8 to 130mm. These are mainly used for gas phase applications because of their low pressure drop, high mechanical strength and low dust content.
Bead activated carbon (BAC) is made from petroleum pitch and supplied in diameters from approximately 0.35 to 0.8 mm. Similar to EAC, it is also noted for its low pressure drop, high mechanical strength and low dust content, but with a smaller grain size. Its spherical shape makes it preferred for fluidized bed applications such as water filtration.
Porous carbon containing several types of inorganic impregnated with iodine, silver, cations such as Al, Mn, Zn, Fe, Li, Ca, have also been prepared for specific applications in air pollution control especially in museums and galleries. Due to its...

Butanol Essay

863 words - 3 pages 1 Butanol is a compound called an alcohol. This is because of a hydrogen atom of a carbon compound is replaced by an -OH group. From butane we get butanol. Alcohols formed from alkanes are called alkanols and have the general formula CnH2n+1OH. Butanol is a liquid at room temperature because of the hydrogen bonding that has strong intermolecular forces so allows butanol to have a much higher boiling point. Butanol is made from the fermentation

The material was compressed over the years by sand and dirt, leaving the form of a carbon known as coal. The
