Test method for active coke cyclic desulfurization and denitrification performance

The invention relates to a test method for active coke cyclic desulfurization and denitrification performance. The method comprises the steps of filling a desulfurization and denitrification reactor with active cokes; cyclically carrying out N times of desulfurization-denitrification-active coke regeneration, wherein the N is greater than 1; and calculating active coke desulfurization efficiency and active coke denitrification efficiency in each cycle. In a cycle, the desulfurization and denitrification reactor works at a desulfurization reaction temperature, a denitrification reaction temperature and an active coke regeneration reaction temperature in sequence. A desulfurization reaction gas is a mixed gas of SO , O , H O and N . A denitrification reaction gas is the mixed gas of NO, NH , O , H O and N . In a regeneration phase, nitrogen is imported into the desulfurization and denitrification reactor. Through control over a working mode of the desulfurization and denitrification reactor, many times of desul
