Petrochemical activated carbon filter activated carbon filter manufacturing process petrochemical manufacturing process consists of: a first, including dehydration and carbonization, the raw material is heated at a temperature of 170 至 600 ℃ drying, the original organic matter about 80% charring. Second, is to make the charcoal-activated, it is through the use of activators such as water vapor and carbon to complete the reaction, the endothermic reaction is mainly in the mixed gas consisting of CO and H2, for burning charcoals heated to a suitable temperature (800 to 1000 ℃), to burn them all biodegradable material, the resulting well-developed porous structure and huge specific surface area, which has a strong adsorption capacity. In order to unify the standard decolorizing carbon, so that production can be controlled based in the activated carbon industry generally or with iodine adsorption adsorption of carbon tetrachloride (CTC) to calibrate the activated carbon adsorption, the higher the adsorption, the adsorption capacity of the activated carbon more strong. Petrochemical activated carbon filter is mainly used in the petrochemical industry in the E-deodorizer (refined sweetening), ethylene desalinated water (refined filler), catalyst support (palladium, platinum, rhodium, etc.), water purification and sewage treatment; chemical catalysts and carrier gas purification, solvent recovery and oil and other bleaching, refining. Iodine value is defined: A measure of the degree of unsaturation of the fat, is equal to the number of grams of iodine 100g fat ingested. Detection of activated charcoal to smelt activated carbon starch solution as indicator, titrated with standard sodium thiosulfate solution. Iodine Value Description big fat high in unsaturated fatty acids, or highly unsaturated degree. Represents an indicator of unsaturated organic compounds degree. Refers to the substance can absorb 100g (plus) the number of grams of iodine. Mainly used to determine fat, fatty acids, waxes, and polyester-based material. Unsaturated greater extent, higher iodine value. Drying oil has an iodine value greater than the non-drying oil the iodine value. Decolorized with activated charcoal for citric acid are two major categories: powdered activated carbon and granular activated carbon. For citric acid fermentation broth can also be processed using granular activated carbon. Granular activated carbon compared to powdered activated carbon, has the continuity, cycle characteristics, increase work efficiency, while reducing environmental pollution. Currently, citric acid adsorption performance bleaching has been in use granular activated carbon adsorption index 维尼隆 carbon carrier, that depends on how much acid adsorption properties of activated carbon adsorption to define quality of decolorizing charcoal, this indicator can be part of the explanation of activated carbon adsorption properties, but does not apply to the citric acid decolorization accurate. Citric acid is used as the granular activated carbon adsorption process is to be adsorbed dye solution, or even some of the other macromolecules adsorbed substances, and the molecular diameter acetate only 0.51nm, and Pigment macromolecules diameter far Therefore, activated carbon adsorption pore size range acetate represented not represent its adsorption properties of macromolecular pigment. Currently, commonly used bleaching adsorption adsorption performance indicators at home and abroad caramel (or molasses value) and methylene blue adsorption properties of activated carbon can be expressed in a large hole and the hole, but due to the current domestic citric acid used in granular activated carbon adsorption and Other decoloration granular activated carbon to the hole most of the main, the large number of little holes, little caramel value, so the use of methylene blue adsorption Asia to illustrate the granular activated carbon adsorption of citric acid bleaching ability is more accurate.
