载溴高硫石油焦活性炭脱汞实验研究
Experimental Study on Mercury Removal of High-Sulfur Petroleum Coke Activated Carbon Impregnated With Bromine
摘要
Abstract
As a petrochemical industry by-product, petroleum coke with high sulfur content was made into activated carbon, and then treated by NH4Br solution for modification with Br uploading on its surface. The prepared petroleum cokes were characterized by means of nitrogen (N2) adsorption/desorption, and scanning electron microscopy/X-ray energy dispersive spectroscope (SEM-EDS). Experimental studies on Hg removal were investigated in both a fixed bed and an entrained flow reactor system. Petroleum coke activated carbon modified by NH4Br performs better mercury adsorption capacity than commonly used activated carbon from coal. It is noted that 1% additive of NH4Br into the petroleum coke activated carbon nearly remove all the mercury in a fixed bed within 120 min, and the mercury removal efficiency of entrained flow reactor system under condition of 120℃, 2 second residence time and about 90 000 C/Hg ratio is above 90%. The results solidly support that the modified high sulfur petroleum coke can be used as high effective mercury removal adsorbent in a flue gas injection of demercuration system for coal fired power plant.关键词
