摘要： : Sulfur oxides contained in the flue gas from coalfired boilers are adsorbed by an adsorbent prepared by dry-distilling a portion of the fuel coal satisfying at least one of the following requirements: an ash content lower than 15 % by weight and a fixed carbon content of at least 50 % by weight; thereby producing semi coke, and activating the semi-coke by steam. After use, the adsorbent is heated to desorb the adsorbed sulfur oxides in a high concentration. The desorbed sulfur oxides are passed through a bed of semi-coke before the activation to recover the sulfur oxides as elemental sulfur.

摘要： PURPOSE: To prepare a desulfurizing agent high in adsorbing performance economically by a method wherein the surfaces of coal are oxidized by combustion gases in a carbonizing step for coal, when preparing the desulfurizing agent used for a dry type exhaust-gas desulfurizer from coal.
CONSTITUTION: When preparing the desulfurizing agent used in a dry type desulfurizing process for removing sulfur oxides in combustion exhaust gases by the carbonization and activation of coal, a part of combustion gases is contacted to coal before or after the carbonizing step so as to oxidize the surfaces of the coal or the carbonized coal, followed by activation. By such a treatment, oxides are formed on the surfaces of the coal or the carbonized coal, whereby the succeeding activation reaction is facilitated and development of pores is accelerated. Accordingly, a desulfurizing agent having high adsorbing performance can be prepared at low cost.

摘要： PURPOSE:To reduce the cost of fuel and to effectively use heat source by a method wherein a carbonaceous adsorbent damaged in the process of adsorption and desorption is combusted as a heat source for regenerating adsorbent used in the dry type exhaust gas desulfurization process. CONSTITUTION:In the dry type exhaust gas desulfurization equipment using a carbonaceous adsorbent, the carbonaceous adsorbent pulverized by repeated adsorption and desorption is combusted to heat a heat medium such as river sand or alumina thereby to form a high temperature heat medium 506. The heat medium 506 is supplied to a desorption column 104 and used as the heat source for regenerating process of the adsorbent. Thereafter, the heat medium is handled by a classifier 520 to be classified into a desulfurizing agent 15 and heat medium 523. The desulfurizing agent 15 is returned to a moving layer adsorber 101, and the heat medium 523 to a medium fluidized layer 501. In this manner, the heat source is effectively used and the cost is reduced.

摘要： PURPOSE:To enhance removal efficiency of SOx and to attain to reduce a desulfurizing cost, in removing sulfur oxide in a waste gas of coal combustion from a boiler or the like, by using coal of which a wt. ratio of ash and fixed carbon is a specific value respectively as stock coal for a desulfurizing agent. CONSTITUTION:Coal whose wt. ratio of ash is 15% or less and that of fixed carbon is 50% or more, for example, Ermelo coal is crushed and classified by a crushing machine 107 and a classifying machine 108 and, thereafter, sent into a dry distillation and activating furnace 109 to prepare a desulfurizing agent. The obtained desulfurizing agent is sent to a moving layer adsorbing tower 101 by a conveying machine 110 and contacted with a waste gas from a boiler 100 in a crosswise stream mode to adsorb and remove SOx. The treated gas is discharged to the air through a dust removing machine 105 and a chimney 106. The SOx adsorbed desulfurizing agent is sent to a desorbing tower 102 from the adsorbing tower 101 to be regenerated therein and, after fine coal is removed by the classifying machine 104, returned to the adsorbing tower 101. On the other hand, a desorbed gas 7 is sent to a sulfur element recovery apparatus 103 to recover sulfur.

摘要： PURPOSE:To reduce the amount of movement of adsorbent in a moving layer adsorption column for treating waste gas from coal combustion boiler by a method wherein plural desulfurization sections of adsorbent layers are arranged in the direction of a treating gas flow, and adsorbent having different adsorption capacities are selectively used. CONSTITUTION:To use typically the change in the height of adsorbent layer, a treating gas 3 passes through adsorbent layers a', b', c' having different height and at right angle to the gas flow direction and exits as gas flow 4. The adsorbent 1 moves downward and taken out by the extracting machines 6 for regeneration. To use the adsorption column of this invention for desulofurization for waste gas of the boiler, it is practical to change the speed of moving the adsorbent in each desulfurization section. This added with a combination of adsorbents having different adsorption capacities results in the reduced amount of circulated or consumed adsorbent and improves the control response of a desulfurization equipment.
