Car urea market development opportunities ushered from the diesel car ownership, the market demand will achieve rapid growth. 2011 domestic sales of 880,600 heavy-duty diesel vehicles, 2012 sales of 636,000 vehicles in Hebei urea, 2013 annual sales 750 000 - 760 000. Related professionals to predict, including heavy diesel vehicles equipped with SCR system at a rate of at least 500,000 of annual growth, the end of 2015 China IV diesel car ownership is expected to reach 1.25 million in theory, by the end of 2017 can theoretically reach 2.25 million vehicles. According to diesel production estimates, is expected to 2018 China's automotive market capacity will reach 7 million tons of urea. So Shandong car with urea, urea market size car with a sharp increase will become a trend. General performance indicators to measure and evaluate the traditional activated carbon adsorption, including iodine value, methylene blue adsorption, carbon tetrachloride adsorption, surface area, milling strength and ash, etc., especially iodine value, methylene blue, and carbon tetrachloride value, direct response the activated carbon adsorption of organic matter. But often appear activated carbon adsorption performance in general and field test results do not match, the relevant question is not good, mainly due to iodine value, methylene blue value, and carbon tetrachloride adsorption, etc. is the use of small molecules (such as iodine molecule diameter of about 1 -1.5nm, methylene blue molecule diameter 1.5-1.8nm urea solution between car prices, carbon tetrachloride molecule diameter of 0.71nm) adsorption test, the measured absorption values ??are representative of activated carbon for these small organic molecules adsorption capacity, and these small molecules in water treatment compared with activated carbon adsorption object, there is a big difference in the molecular volume. Small molecules can reach a lot of microporous activated carbon inside, macromolecules can not go in, of course, can not be adsorbed, so the small molecule adsorption ability of activated carbon adsorption of macromolecules is not necessarily good. Characterized by a specific surface area also has the same problem, the amount of adsorption of organic molecules in water depends on the pore size distribution of activated carbon instead of the activated carbon the specific surface area, however, by measuring the pore size distribution of activated carbon like activated carbon is selected relatively time-consuming, laborious.
