脱硫活性炭简介：
脱硫活性炭是一种含硫材料制成的外观呈黑色、无味、***，内部孔隙结构发达。比表面积大，吸附能力强的一类微晶质碳素材料，是一种常用的吸附剂。 活性炭按外观形状分为：粉状、颗粒状、不规则颗粒状、圆柱形、球型和纤维状等。脱硫活性炭指的是在汽油精制过程中，利用活性炭负载磺化钛氰钴，对原油中超标硫醇进行脱除，从而减少汽油含硫量，提高品质。符合国家环保排放的要求。
脱硫活性炭特点：
① 比表面积大、吸附值高。作为装载磺化钛氰钴的活性炭，要求亚甲蓝吸附值要高，中孔发达，负载量超过普通活性炭。
② 强度好，不易碎。由于负载磺化钛氰钴活性炭，要在固定床中反复接受压力考验，溶液浸泡，所以要求强度要高，颗粒是自然形状。
③ 灰份杂质含量少。为了确保催化剂顺利进行化学反应，要尽量减少炭中灰份，金属离子等各种杂质含量。提高活性炭孔隙利用率。
④ 水分低。尽可能保持活性炭***水分，避免影响其功能发挥。
脱硫活性炭按生产原料可分为：
活性炭脱硫剂有两种:一种是用于粗脱硫的普通活性炭脱硫剂,还有一种是用于精脱硫的改性活性炭脱硫剂.前者常以煤为原料,以焦油为胶粘剂挤条成型后经炭化处理,再用水蒸气活化,经筛分后制成.后者常选用已成型的活性炭,用活性炭金属盐容液等浸渍后,再经干燥、焙烧和过筛后制得.如在活性炭上涂渍上乙醇胺等可以使活性炭得以改性,能脱除大部分的有机硫醚.

Desulfurization of activated carbon properties:
English name: goff mercaptan carbon
Chinese name: mercaptan activated carbon
Desulphurization activated carbon by appearance shape can be divided into: powder and granule and irregular granular, cylindrical, spherical, and fibrous, etc. Is a kind of sulfur the appearance of the material in black, tasteless, non-toxic, internal pore structure are developed. Is greater than surface area, strong adsorption ability of micro crystalline carbon material, is a kind of commonly used adsorbent. Desulphurization activated carbon is in the process of refined gasoline, using activated carbon load sulfonated cobalt, titanium cyanide for crude oil in overweight mercaptan removal, thus reducing the gasoline sulfur content, improve the quality. In line with the requirements of state environment protection.
Preparation:
Desulphurization activated carbon has two kinds: one kind is used for coarse ordinary desulphurization activated carbon desulfurization, another is used for modification of fine desulfurization desulfurization of activated carbon. The former often with coal as raw material, with extrusion molding article after carbonization tar for adhesive processing, again by steam activation, after screening. Latter often choose has formed activated carbon, activated carbon with a metal salt solution after impregnation, after drying, roasting and sieving system. Such as ethanol amine on the coating on the active carbon can make the activated carbon can be modified, can removal most of the organic sulfur ether.
The desulfurization characteristics of activated carbon:
(1) large specific surface area, high adsorption. As activated carbon loading of sulfonated cobalt titanium cyanogen, methylene blue adsorption value is higher, the hole developed, load more than the normal active carbon. (2) good strength, not easy broken. Due to load sulfonated cobalt titanium with activated carbon, to accept the pressure test again and again in the fixed bed, solution soaked, so demand higher intensity, particle preferably natural shape. (3) ash less impurity content. Chemical reactions to ensure that the catalyst smoothly carries on, try to minimize carbon in ash, metal ion and other impurities. Raise the utilization ratio of the activated carbon pore. 4. Low moisture content. As far as possible keep minimum water activated carbon, avoid affecting its function.
Using the matters needing attention:
Within 5 ~ 60 ℃ temperature some good desulphurization activated carbon desulfurization efficiency. Above 60 ℃, due to the table in the adsorption of activated carbon sulfide is weaker, therefore its desulfurization effect declined. Activated carbon desulfurization in dry gas desulfurization effect is poor, the requirements of purified gas relative humidity is 70% ~ ***, and, when necessary, should be properly hydrated. Because of fine desulfurizer in the process of preparation of activated carbon has added some appropriate can greatly speed up the reaction of active component, so don't need like activated carbon when using coarse desulfurization agent that add ammonia in raw material.
Due to unique specific surface area activated carbon and microporous structure characteristics, it can absorb the high boiling point of organic sulfur compounds, but of COS and CS2 low boiling point organic sulfide adsorption quantity is small, and transformation of EZX except closed type multi-functional fine desulfurizer. Fine desulfurizer can reach 1 ~ 3 years service life generally don't need regeneration. But fine desulfurizer can jam because of adsorbed gas in coal tar channel influence sulfur capacity, will also because of the gas in unsaturated hydrocarbon and larger molecular weight of polymer and polymerization reaction of covering surface and reduce the sulfur capacity. So should be removed in advance before the fine desulfurization process of raw material content is higher in the coal tar.
Desulphurization activated carbon is one of the first to use the dry process desulphurization agent, has been 70 years history. The use of previously activated carbon desulfurization technology and equipment for large, regeneration and sulfur recovery process is relatively complex, annoying lock operation. In the 1950 s was gradually replaced by wet method. In recent years because of the regeneration methods to improve and simplify, and developed the fine desulfurization by activated carbon desulfurization and the ambient temperature fine desulfurization technology, there are many medium and small ammonia plant, NiaoSuChang, alcohol plants using desulfurization dry active carbon removal and part of the organic sulfur in raw gas. This method has a large sulfur capacity, strong adaptability, low operation temperature, and the advantages of renewable can repeatedly use and recovery of sulfur, and the price of activated carbon desulfurization is cheaper. But the desulphurization activated carbon are limited to aerobic, anaerobic sulfur absorption ability is low. In terms of resistance to water, activated carbon is better than that of ferric oxide desulfurizer for desulphurization.
Desulphurization mechanism:
Activated carbon desulfurization mechanism is the use of activated carbon surface active groups accelerated the catalysis of gas H2S and O2 of the following reaction:
H2s + O2 and h2o + 2 s 2 2 Δ H = 434.3 kJ/mol
H2S and O2 on the surface of the activated carbon, reaction is actually divided into two steps, first is active carbon adsorption on the surface of oxygen, the surface of the active center formed oxide, and H2S in the gas molecules react with chemical adsorption of oxygen, generated by the sulfur deposition in the microporous activated carbon as ash. In order to accelerate the reaction, improve the effect of desulfurization, the ratio of the actual O2 / H2S should be larger than the theoretical value of 0.5, the ratio is greater than 3 as well.
Desulphurization activated carbon may be too impregnation method introducing active metal such as copper delimit, alkali metal, alkaline earth metal, etc., to modified to improve its catalytic activity.
Activated carbon packing:
25 kg/bag or 20 kg/bag, inside plastic outside double packaging, export products are also available ton bag packaging, the packaging can be adjusted according to customer requirements production.
