Received: 17 January 2012; in revised form: 15 February 2012 / Accepted: 26 March 2012 / Published: 17 April 2012 Abstract: Magnesium nickel silicate (MNS) has been investigated as a catalyst to convert tars and light hydrocarbons to syngas (CO and H ) by steam reforming and CO reforming 2 2 in the presence of H S for biomass gasification process at NexTech Materials. It was 2 observed that complete CH4 conversion could be achieved on MNS catalyst granules at 800–900 °C and a space velocity of 24,000 mL/g/h in a simulated biomass gasification stream. Addition of 10–20 ppm H S to the feed had no apparent impact on CH conversion. 2 4 The MNS-washcoated monoli
