Obiettivo THE AIM OF THE RESEARCH IS TO ESTABLISH IF ANTHRAQUINONE WORKS AS A PULPING AID IN THE NEUTRAL SULPHITE SEMI-CHEMICAL PULPING OF EUROPEAN HARDWOODS IN THE WAY IT HAS WORKED IN OTHER PULPING PROCESSES, PRINCIPALLY THE ALKALINE PULPING OF SOFTWOODS. THE ANTICIPATED BENEFITS TO BE GAINED ARE HIGHER PULP YIELD, LOWER CHEMICAL USAGE AND LOWER REFINER ENERGY REQUIREMENT. IT IS ANTICIPATED THAT POTENTIALLY, PULP YIELD COULD BE INCREASED BY 2 - 3 % AND A REDUCTION IN CHEMICAL ADDITION OF UP TO 2% ON WOOD COULD BE ACHIEVED. THE RESEARCH PROJECT IS AIMED AT INVESTIGATING THESE ASPECTS OF USING ANTHRAQUINONE BY MEANS OF AN EXTENDED LABORATORY STUDY COMPRISING A SERIES OF WOOD PULPING TESTS. THESE WILL INVESTIGATE LEVELS OF ANTHRAQUINONE REACTION TIME AND TEMPERATURE AND PROCESS PH. RESULTS WILL BE MONITORED BY MEASUREMENT OF CHANGE IN % YIELD LIQUOR CONSUMPTION, REFINER ENERGY REQUIREMENTS AND PULP QUALITY.
