Near the end of the month, temperatures soared, but the demand for Shenzhou profiles did not have a concentrated explosion. Today, the opening of the market, some of the local profile slightly pulled up, but the transaction was affected by the shortage of resources but decreased. Traders said that the current situation is more embarrassing, there is no goods at the beginning of the month, the current market is no goods, the market is very frustrating for businesses. Recently, there have been very few supplements for the arrival of resources in Shencheng. Some of the resource prices have risen sharply. In view of the frequent overhaul of mainstream steel mills and the tight funding, most businesses have a wait-and-see attitude, and their enthusiasm for stocking is not high, as inventory levels gradually decline. The support under the local profile is obvious, and there is a higher probability of continuing upward in the later period. To sum up, the recent price of local profiles will be mainly oscillating upwards.
1. Product introduction
Coal-based Column Denitrification Column Activated Carbon is cylindrical black particles. It has many characters, such as high porosity, high sulfur capacity, high desulfurization efficiency, large surface area, light weight, strong adsorption capacity, wear resistance, good water resistance, low air resistance, easy regeneration, not easy to break under high pressure etc. It is a commonly used in adsorbent.
2. Adsorption purification principle and process
Coal-based denitrification Activated Carbon is divided into large pores (pore size greater than 50nrrt), the middle hole (pore size between 2 ~ 50nm) and micro-pore (pore size less than 2nm) three categories.
The denitrification activated carbon is by active carbon`s adsorption and catalytic activity of activated carbon. The strong catalytic effect of the active carbon for sulfur dioxide in gas, and a small amount of Oxygen in the oxidation reaction, the reaction of elemental S adsorbed the surface of activated carbon. When activated carbon desulfurization agent the adsorption reaches saturation, the desulfurization efficiency decreased obviously, it must carry on the regeneration. The regeneration of active carbon adsorption depends on the material, sulphur began to melt under atmospheric pressure is 190 degrees, 440 degrees Celsius will sublimate into gas, therefore, the general use of superheated steam temperature of about 450-500 degrees Celsius for the regeneration of activated carbon desulfurization agent. When the desulfurization agent reach high temperature, the elemental sulfur separate out activated carbon, the precipitation of sulfur into sulfur recovery pool, water cooled to form solid sulfur.
