石灰石脱硫反应活性的研究

The Study in Limestone Desulphurization Reaction Activity

采用气测法，在流化床模拟试验台上，对２０个天然石灰石样品进行了脱硫反应特性的测定。通过对实验数据的线性回归，获得了每个石灰石样品的脱硫反应活性数据一反应速度常数Ｋ，并建立了石灰石化学成分对Ｋ影响的预测模型。从而，为燃煤发电厂在选择吸收剂种类时提供了重要依据。

Adopting gas-testing method, 20 samples of natural limestone have been testedfor characteristics of desulphurization reaction on fluidized bed analyogue experiment.Passing linearregression for testing datas, the active data of every sample of limestone in desulphurization reaction-rate constant K can be worked out, and a caluculating model has been esteblishedfrom limestone's chemical components with K Thus, the important basises were provided, when wechoose kinds d the absorbing agent for power station of boming coal.
