摘要
报导了福建无烟粉煤在碱性催化剂作用下的催化气化工作进展，在小型Φ１８ｍｍ固定床与Φ２０ｍｍ流化床中，进行了水蒸气气化、混合气（空气／水蒸气）气化，采用复合１催化剂添加量８％，８５０～９００℃及流化床条件下，即可获得产气率Ｖ＞３ｍ３／ｋｇ煤（无催化剂时，Ｖ＜１．６ｍ３／ｋｇ煤）及煤气热值ＱＬＶＨ＞９ＭＪ／ｍ３（水蒸气气化）与＞６ＭＪ／ｍ３（混合气气化）的结果，并与无烟煤气化的工业装置进行了比较。
The catalytic gasification using alkali matter for Fujian pulverized anthracite is firstly reported by this study It indicates that under the normal pressure with the temperature ranging from 850 to 900 and the catalyst (compound catalyst 1) content of about 8%, a higher gas yield (TBXV >3m3/kgcoal) can be produced either in a 18mm fixed or in a 20mm fluidized bed Gas with higher heating value ( Q LVH>9MJ/m3) or lower heating value ( QZLVH>6MJ/m3) can be also achieved by the stream gasification or the mixing (stream/air) gasification Obviously, the results arisen from this experiment, in which an special Fujian anthracite with a low ash-fusing point was gasified successfully, are quite better than that obtained from some industrial set of coal gasification even employing the lump coal Therefore, it will provide the important information and basis for the further commercial development of coal catalytic gasification4HZ
