Title : Hydrogen rich syngas using steam gasification of mixed food waste via nickel based catalyst


This study focuses on use of Ni as a catalyst in steam gasification of food waste to enhance syngas yield and hydrogen fraction in it. Nickel is a popular earth metal which is widely used as catalyst in organic chemistry. In this study, 5% Ni was loaded on food waste ash using the traditional impregnation method. Food waste ash was produced by heating ground food waste in muffle furnace up to 800°C.  The Ni loaded on food waste ash showed high potential in cracking the tar produced by gasification of food waste. Food waste ash also contains different alkaline oxides which can act as catalyst in direct or indirect ways.  Prepared catalyst was mixed with Food waste in equal proportion and then used as feedstock for steam gasification. 100 gm of such mixture was used in steam gasification which was conducted in a fixed bed gasifier at 800 oC with steam flow rate fixed at 0.75 ml/min. Several parameters for evaluating the gasification performance of food waste in presence of 5% Ni catalyst was determined such as syngas yield, syngas composition, hydrogen yield, High Heating Value and Carbon Conversion Efficiency. The use of catalyst increased the syngas yield from 0.94 to 1.05 m3/Kg. It was also observed that hydrogen fraction increased by 20% and CO fraction increased from 11.8% to 22.65%. The increase in high heating value and carbon Conversion efficiency was found to be 17% and 63% respectively. 

Audience Takeaway Notes: 

  •  Audience will be able to learn new technique of food waste management using thermochemical process like gasification. 
  • This will not only provide a new method of waste management but also produce energy out of it.
  • This is an interdisciplinary research and the researcher and teachers will learn how interdisciplinary approach can solve a big problem like food waste management.
