摘　　要：目前造纸废渣的主要处理方式为焚烧,虽然该工艺简单有效,但会产生二噁英等有害物质,因此部分地区环保部门开始限制新建焚烧项目。针对造纸废渣处理难的问题,结合废物特性,探索使用气化工艺对其进行处理。在700~900℃利用水蒸气与造纸废渣共同反应制取富氢燃气,并进一步研究了CaO、MgO作为催化剂对气化反应的影响。结果显示:气化温度为900℃,产气中H2的比例超过50%;两种催化剂均可催化大分子有机物分解为气体小分子,导致燃气热值及气化效率提高。At present,the main way to treat papermaking waste residue is incineration.Although this process is simple and effective,it can produce harmful substances such as dioxins.Therefore,environmental protection departments in some areas have begun to restrict the construction of new incineration projects.Aiming at the problem of difficult treatment of papermaking waste residue,combined with the characteristics of waste,explore the use of gasification process to treat it.Hydrogen-rich gas was prepared by the reaction of water vapor and paper waste residue at 700〜900°C,and the effects of CaO and Mg0 as catalysts on the gasification reaction were further studied.The results show that the proportion of H2 in gas production is more than 50%when the gasification temperature is 900 C.Both catalysts can catalyze the decomposition of macromolecular organic matter into small gas molecules,resulting in increase of gas heating value and gasification efficiency.
