摘要
F-T固废由含油铁基废催化剂和稳定渣蜡组成,含有55%～65%的蜡质组份,属于危废.文中通过将F-T固废与水煤浆气化装置煤粉进行共混复配,研究了F-T固废黏附特性调控,添加F-T固废的水煤浆表观黏度、静态稳定性等成浆性能,为在气化装置上掺烧F-T固废,实现资源化利用提供了可靠的实验数据.结果表明:添加烷基酚聚氧乙烯醚或十二烷基苯磺酸钠,可以有效改善F-T固废的黏附特性;相同成浆浓度下,含有F-T固废的水煤浆表观黏度随固废含量增加而增大;当添加10%F-T固废,水煤浆最大成浆浓度由62.2%下降到了60.7%.
Abstract
F-T solid waste is composed of oily iron based waste catalyst and stable slag wax,which contains 55%～65%wax components and belongs to dangerous waste.In this paper,by blending F-T solid waste with coal powder in coal water slurry gasification unit,the regulation of adhesion characteristics of F-T solid waste was studied respectively,and the apparent viscosity and static stability of coal water slurry slurry with F-T solid waste were added to provide reliable experimental data for blending F-T solid waste in gasification unit and realizing resource utilization.The results show that adding alkyl phenol polyoxyethylene ether or sodium dodecyl benzene sulfonate can effectively improve the adhesion properties of F-T solid waste.At the same slurry concentration,the apparent viscosity of CWS containing F-T solid waste increases with the increase of solid waste content.When 10%F-T solid waste is added,the maximum slurry concentration of CWS decreases from 62.2%to 60.7%.
