    • PURPOSE: An apparatus and a method for controlling the ammonia occlusion amount of a selective catalytic reduction system are provided to enable the spraying of urea solution to be accurately controlled to generate ammonia since ammonia consumption is accurately predicted on the SCR(selective catalytic reduction) system. CONSTITUTION: An apparatus for controlling the ammonia occlusion amount of a selective catalytic reduction system comprises a SCR catalyst, first and second temperature sensors, an NOx sensor and a controller. The occluded ammonia reacts with NOx by the SCR catalyst to purify the NOx. The first and second temperature sensors detect the temperatures of the front and rear ends of the SCR catalyst. The NOx sensor detects the amount of NOx, which flows into the SCR catalyst. The controller calculates total ammonia required for the SCR catalyst and controls occlusion.
