FICFB-Reactor - Thermal Gasification

The Hofbauer Reactor is the world´s first functioning FICFB (Fast Internally Circulating Fluidized Bed) plant. The core of the plant is formed by the two inter-connected fluidized bed systems of the fluidized bed steam gasifier (reactor).

In the gasification zone the cut-down biomass is whirled up and gasified in anaerobic conditions at approx. 850°C in the shortest time possible by introducing steam. The bed material (olivine sand) has the function of a heat transfer medium and provides a stable temperature in the reactor.

In the next step the resultant product gas is purified and cooled. The heat emitted during cooling is used for the generation of district heat. Subsequently, the gas is filtered, and tar scrubbed with bio-diesel. In this specialized process all resulting residual materials are recycled.

In the gas purification neither solid waste nor waste water arises, and the product gas is completely free from nitrogen. Fluidized bed steam gasifiers work extraordinarily reliably and regularly (7,000-8,000 operating hours per annum) and are considered state-of-the-art (Best Available Technology).

A downstream engine optimized for gas operation can produce electric power and heat from the product gas (combined heat and power, CHP), with the overall efficiency being higher than 85%. Alternatively, a methanization plant also allows the generation of bio synthetic natural gas (BioSNG) from product gas in certified quality. The product gas consist of up to 40% of hydrogen, which can be extracted; in Fischer-Tropsch-Synthesis high-grade fuels can be synthetisized from the product gas.

The GRE Multi-Fuel Plant, the logical advancement of the plant developed in Güssing and in use there since 2002, reliably provides energy with system relevance – i.e., a minimum of 7.000 hours per annum – and, in addition to the feedstock wood, also allows waste materials rich in hydrocarbon, dried sewage sludge, and the like, to be used as feedstock for gas generation.

The energetic exploitation of waste otherwise unusable as a material is increasingly becoming of interest to communities, as waste management presents an enormous logistic and financial burden which will still increase in the future. In gas generation the toxic potential of the waste is eliminated without causing harm to the environment.

What is used here, is fractions of high caloric value from the mechanical-biological processing of domestic waste, domestic-waste-like industrial waste, and the like. The construction of the GRE Hofbauer Reactor is more than 50% cheaper than that of comparable waste combustion plants.

The advancement was realized with the scientific support of the Vienna University of Technology (Prof. Hermann Hofbauer) and our strategic partner, the experienced energy business consulting firm Consulectra (an affiliate of the RWTÜV Group).

The planning of the Multi-Fuel Plant has been completed, documented and certified, the application for a patent will be filed shortly. Blueprints for putting it into practice are ready. This makes Güssing Renewable Energy the world´s only enterprise which is in a position to offer this technology on a realistic basis. Owing to the cooperation with the Vienna University of Technology GRE has a technological lead of 10-15 years.

new crops for energy production part 1

In Burgenland, Austria an energy crop is being cultivated, which could be utilized in the Hofbauer-Reactor for the production of energy. We visited the person who runs the plantation and asked him about his experiences with the crop.

executives of Asian companies visit Gussing

At the end of October 2013 delegations of Asian companies visited Gussing to see the operating Hofbauer-Reactor, as they are eagerly interested to import this efficient and CO2-neutral technology in Thailand and in Japan. The delegations represented executives from Siam Cement Public Company Limited, Satake Corporation and Mitsui Engineering & Shipbuilding Co., Ltd. .

tech flash gasification animation -> polygeneration

This animation of the Hofbauer-Reactor will show you how we produce a multitude of energy-products such as electricity, heat, natural gas and liquid fuels from carbonic residues. We call this process "polygeneration". Instead of combusting the waste material, which create additional CO2 in the atmosphere, our gasification technology is 100% CO2-neutral.

tech flash liquid fuels from biomass through Fischer-Tropsch synthesis

In this video we show you how we convert biomass to liquid fuels. Through Fischer Tropsch synthesis, the cleaned syn-gas from the Hofbauer-Reactor can be turned into waxes for further refining to liquid fuels. With the side-by-side comparison, you will see the advantages of biomass derived fuels compared to fossil fuels.
