Production of synthetic natural gas in a fluidized bed reactor

Jan Kopyscinski, April 2010

Hello everybody,

This is my first message here in this forum. My former colleague (Johannes) sent you already the link to my PhD-Thesis (see below). I just want to give some more information about my work as a Doctoral Student at the Swiss Federal Institute of Technology (ETH Zurich) and at the Paul Scherrer Institute (


Grass for Power Generation

Grass for Power Generation
Johanes Judex, PSI April 2010

Hello everybody,

I have learned from this gasification network since three years and I learned a lot.
Thank you all, for sharing much information.

Most of the time I stayed in the background but now I want to post the link to my PhD thesis I did at the ETH Zuerich and Paul Scherrer Institut in Biomass Gasification.

I am not a native english writer so you will excuse the formal mistakes I made. Anyway I did my best to present:

Grass for power generation -- extending the fuel flexibility for IGCC power plants

The outline of the work is as follows:

The fuel: natural native grass (extensive), wood
The gasifiers: bubbling fluidised bed (5-10kW) & single pellet reactor
The sampling: continuous wet scrubber
The diagnostik: GC, GC/MS, ICP-OES, TC, Karl-Fischer, Draeger tubes, SID
The parameters: Lambda, temperature, bed material
The goal: Stable operation, product gas clean enough for gas turbine applications
The result: you have to read it and decide for yourself

Well, I hope there is something for everybody in this work.

World Bank Group Energy Strategy

The World Bank have launched online consultations for the World Bank Group Energy Strategy. The online consultations are part of broader effort to gather input from a wide range of perspectives on how the Bank Group can best help developing countries improve the access and reliability of energy while helping facilitate the shift to a more environmentally sustainable energy development path. In addition to collecting comments online, WBG will hold a series of meetings, videoconferences, and other events in the first phase of consultations from February 2010 to June 2010.


Smith Spun-Glass Tar Extractor

Jeff Davis, January 2010

The below text is from "Gas Engines and Producers", Marks.

The apparatus shown in Fig. 39 is a recent development in gas cleaning.

With this type of apparatus the standard anthracite producer is used with bituminous coal and no attempt is made to fix the resulting tar.

Danish Technological University Updraft Gasifier Plant

Danish Technological University Updraft Gasifier Plant
DTU, Denmark, September 1, 2009

DTU Updraft Gasifier and Stirling EngineDTU Updraft Gasifier and Stirling Engine

Today, operation started on Stirling DK's latest installation situated on the campus areas of the Technical University of Denmark (DTU). Approximately 1% of DTU's total power consumption and 2% of its heat consumption will be supplied by the installation.

The plant includes a Stirling engine with an output of 35 kWe of electrical power. The surplus heat from the plant, in the form of hot water, is fed into the district heating system of the DTU campus.

The plant is fuelled by wood chips originationg partly from cuttings from DTU park areas. In this way, the plant is a stand-alone facility that enables DTU to become partly self-sufficient with CO2-neutral power and heat from locally availabel fuel sources.

More information about the project can be found here.
