中文摘要:
      针对利用碳热法还原重晶石生产硫化钡工艺中,因固体碳还原剂带入灰分导致产品硫化钡纯度低,硫酸钡转化率不高等问题。采用液化石油气替代固体碳作为还原剂对重晶石进行还原,考察了气体流量,反应温度以及反应时间对重晶石转化率的影响。结果显示,反应时间对重晶石的还原率影响较大,其次是反应温度和气体流量,在气体流量1.5L/min,反应温度1150℃,反应时间90min的条件下,重晶石的转化率为95.9%。
英文摘要:
      In the process of producing barium sulfide from barite by carbothermal reduction, the purity of barium sulfide is low and the conversion rate of barium sulfate is not high due to the introduction of solid carbon reductant into the ash. Reduction of barite with liquefied petroleum gas instead of solid carbon as reducing agent. The effects of gas flow rate, reaction temperature and reaction time on barite conversion were investigated. The results showed that reaction time had a great influence on the reduction rate of barite, followed by reaction temperature and gas flow rate. Under the conditions of gas flow rate 1.5L/min, reaction temperature 1150℃ and reaction time 90 min, the conversion rate of barite was 95.9%.
