GASIFICATION OF SEMICOKE OF BROWN COAL FROM THE KANSK-ACHINSK BASIN UNDER PRESSURE. INFLUENCE OF CALCIUM AND SODIUM COMPOUND ADDITIVES

摘要

The reactivity of the semicokes obtained from brown coal of the Berezovo Deposit of the kansk-Achinsk Basin and from brown coal preliminarily mixed with aqueous solutions of calcium or calcium + sodium acetates taken in an amount of 3/100 of Ca or 3/100 of Ca + 1/100 of Na (mass /100_ of the dry coal was compared in Steam and air gasification conducted at 800 deg . C, a pressure of 3 MPa, and a volume Ratio of air:steam = 1:1.
