Thermo-catalytic
reforming - TCR®

Flexible technology platform for energy production and biorefinery based on organic waste & residues

Innovative, Patented Technology Platform

Susteen's flexible technology platform can transform more than 65 different types of organic wastes and residues into energy. The platform is based on the proprietary and patented TCR® technology and has been developed, tested and optimized for more than 20 years at the Fraunhofer Institute for Energy Research UMSICHT.
 
TCR® converts biomass in a multi-stage process (thermal drying, pyrolysis and catalytic reforming) with product treatment and final coal gasification. As a result, we use this process to produce high-quality synthesis gas, bio-oil and biochar.

Feedstock Supply

Feedstock is introduced via a lock system with the absence of oxygen in the reactor system. Possibly, is an upstream pre-treatment of the feedstock is necessary. The system can work with variable moisture content of 10% to over 30%, variable piece size of 3 mm to approx. 30 mm and plastic content of up to 10%.

Carbonization

In a first TCR® reactor stage, the biomass is carbonized to biochar at medium temperatures (400 - 500 ° C), excluding oxygen. Volatile organic compounds and water evaporate. Optimized process conditions and the use of a processintegrated catalyst reduces the formation of unwanted tar.

Catalytic Reforming

In the second TCR® reactor stage, biochar and vapors from the first stage are further heated to 500-700 ° C. These intermediates are further refined by catalytic cracking and reforming.

Product Gas Treatment

The vapor phase is cooled and separated into synthesis gas, oil and water phase. The synthesis gas is freed of particles and aerosols in a purification stage.

The TCR® Process at a Glance

The innovative TCR® process was developed by the Fraunhofer Institute UMSICHT and converts a variety of residual materials into high-quality gas, coal and oil in a robust thermal process.

The product coal is discharged from the reactor system and can be converted into a coal gas, if necessary, in a direct downstream gasifier for generating electricity and heat. This makes sense especially for mineral-rich or contaminated feedstocks. In normal operation, TCR® systems can be completely heated by the combustion of synthesis gas or coal gas. This also makes a self-sufficient, decentralized deployment possible.

The Advantages of TCR® at a Glance

For the energy recovery of organic residues, various processes such as combustion, gasification and biogas technology have been developed.
Depending on the input material, the TCR® process can offer important advantages.

  • With a capacity of around 3000 tonnes of dried feed per year, the TCR® technology is particularly suitable for the decentralized energy disposal of problematic residues such as sewage sludge or market waste with residues of packaging material.

  • TCR® can process almost any solid organic residue after proper processing. Systems can also be designed especially for mixed and variable feedstocks with up to 15% plastic content.

  • TCR® achieves exceptionally high product quality, enabling a wide range of applications. The easiest way is to generate electricity and heat on CHP. Coal and oil can be stored and can be converted into electricity with demand control.

  • For all products, recycling methods are also being developed. For example, the produced oil can be refined into standard-compliant diesel and gasoline fuel. Also of interest is the chemical use of bio-oil and synthesis gas.

  • Synthesis gas can also be used to separate green hydrogen for industrial applications. This is another example of the great potential of the TCR® process.

  • The TCR® process is efficient and robust. More than 80% of the primary energy of the dried feedstock is available after deducting the process heat in the products. Our system design is optimized for robust operation.
