Study on the possibility of using spent RFCC catalysts from Dung Quat Refinery as an admixture for cement
Abstract
Spent catalysts discharged from fluidised catalytic cracking unit are waste materials of the oil refining industry. It is estimated that, on average, each cracking reactor can discharge from 5 - 6 tons of RFCC catalyst per day. In Vietnam, the amount of spent RFCC catalysts which are discharged by the Dung Quat Oil Refinery is about 20 tons per day. To prevent serious environmental risks from this huge amount of waste, the authors have studied the possibility of re-using the spent RFCC catalysts from Dung Quat Refinery as an admixture for cement.
