Abstract：To utilize lignite clean and effectively,introduced advanced drying and gasification technologies of lignite at home and abroad based on the analysis of Vitoria lignite characteristics.Evaporation drying and non-evaporating dehydration technology were the main lignite drying technologies. The technological processes and current states of pulverizer drying technology,lignite ball drying technology,rotary steam tube drying technology and dehydration process with mechanical thermal extrusion were analyzed.The first and third technology were more mature,which were widely used in the industry.The integrated lignite drying and gasification process and the pressurized fluidized bed gasification process were discussed.For the integrated process,it was utilized in coal chemical industry by setting the operation condition in oxygen enriched or pure oxygen and inputting vapour.
Keywords：ligniteevaporation dryingnon-evaporating dehydrationlignite gasificationintegrated drying gasification
