Co-gasification of oily sludge and chicken manure in a laboratory-scale updraft fixed bed gasifier

Abstract

The purpose of this study is to obtain recycled beneficial products with the thermal decomposition of petrochemical industry bottom sludges using gasification processes in a laboratory-scale updraft circulation fixed bed reactor. This work as a result of the gasification experiments carried out at 700-800 degrees C in the presence of limited oxygen results in a waste mass decrease within the range of 64-98%. Furthermore, the calorific value obtained using a mixture of waste consisting of petro-chemistry tank bottom sludge (75%) and dry chicken manure (25%) at 700 degrees C, with a dry air flow rate of 0.05 L/min, is at 3872 kcal/m(3). Depending on the varying experimental conditions, the highest values for CH4 and H-2 gas are measured as 30% vol at 700 degrees C with a 0.05 L/min dried air flow. The co-gasification of chicken manure and petroleum oily sludge is a promising method for achieving sustainable waste management and energy recovery in the concept of waste-to-energy.
