固定碳含量是指通过试验室的方法，将测得的水分、灰分、挥发分从总重量减去，其差值与原样品炭之百分比。
实验结果表明：活化剂改性后的煤沥青，固定碳含量提高。
The results show that the fixed carbon in coal-tar pitch modified with activating agent has been increased.
干燥无灰基固定碳含量增加，着火活化能增加，反应速率减小。
With the carbon content of dry ash-free basis increasing, ignition activation energy increases and reaction rate falls.
一般说来，电站煤质的品位低、灰含量高(低的固定碳含量)，直接气化效果很差。
Generally speaking, the coal of power plant is low-grade, high-ash (the low content of fixed carbon) and the effect of direct gasification is bad.
