Clean biomass-based syngas generation
From Grave-to-Cradle: Creating Value from Sewage Sludge
Short Introductive summary
In this work the pellets produced by Torwash in their pilot plant in Cuijk were tested as feedstock in the indirect gasifier (up to 5 kg/h) at TNO with steam at different temperatures. These pellets are the product of the Torwash patented process that upgrades directly the wet sludge received from a water treatment plant into a solid feedstock. The product gas composition obtained from the indirect gasification is mapped including the presence of contaminants such as HF, NH3, HCN and HCl. The flue gas obtained during the process is continuously monitored with an FTIR. The results will be presented on a volume basis for the main products. The mass balances of the system will be presented in terms of carbon yield based on the total carbon input from the feedstock.

Presenter's biography
Berend Joost (Berend) Vreugdenhil holds an M.Sc. degree in Chemical Engineering from the Technical University Delft. In 2006 he started his career at ECN within the Syngas and SNG group, where research is focussed on developing the technology to produce sustainable natural gas from biomass. The first four years at ECN he was involved in the gasifier research, looking into the effect of bed materials on gas composition, temperature effects and the influence of gasifying medium. Next to this he also looked into the behaviour of tar and more precisely the condensation behaviour of tar in a producer gas.Since beginning of 2011 he is responsible of the tar removal technology developed by ECN, named OLGA, and is coordinating the research program into further optimizing this technology and broadening the range of applications of OLGA. In 2015 he changed in his role to Innovation Manager Gasification, which entails setting out program for gasification within ECN. The area he now is responsible for is gasification, gas cleaning and gas upgrading. Next to the production of substitute natural gas (SNG) from biomass/waste also the production of valuable chemicals (BTX, ethylene) are routes that are being developed
