GT-xCHEM
GT-xCHEM is an exhaust aftertreatment and chemical systems add-on for GT-SUITE with extensive capabilities for emissions reduction and clean technology solutions
Exhaust Aftertreatment and Chemical Systems ModelingWHAT IS GT-xCHEM?
GT-xCHEM unifies the best-in-class capabilities of exothermia suite and GT-SUITE for exhaust aftertreatment and chemical systems solutions and delivers new capabilities essential for the development of regulatory compliant emissions systems. In addition, it supports expansion into chemical systems applications related to the mobility and stationary power industries such as fuel reformers for hydrogen fuel cells, CO2 capture and storage, and other chemical processing applications.
Exhaust Aftertreatment Modeling at its CoreGT-xCHEM FOR EXHAUST AFTERTREATMENT MODELING
GT-xCHEM builds upon a long tradition of exhaust aftertreatment modeling with GT-SUITE including the following highlights:
- Predictive tailpipe emissions with or without integrating with engine, vehicle, controls, etc.
- Design aftertreatment system components (catalyst sizing, washcoat loading, topologies, etc.)
- Can be used for control system development for fuel dosing, urea injection, warmup strategies
- Ideal for drive cycle simulations, real driving emissions (RDE), and real world emissions (route)
- Highly flexible and intuitive user interface for reaction mechanism development
- State-of-the-art mechanisms and validation results for many catalysts and particulate filters
- Fast quasi-2D/3D modeling capability developed from the successful 1D solution
Research and Development for Future ApplicationsGT-xCHEM FOR CHEMICAL SYSTEMS MODELING
The reactor modeling capabilities of GT-xCHEM are adaptable to accommodate research and development of new clean technologies:
- Fuel reformers and cracking catalysts for producing hydrogen for fuel cells and H2 ICEs

Emission Control Technologies for Zero Carbon Fueled EngineEUROPEAN REGIONAL DEVELOPMENT FUND PROJECT
Τhe enterprise EXOTHERMIA SA, which is headquartered in the Region of Central Macedonia, was co-financed by the European Regional Development Fund (ERDF) of the European Union for the implementation of its project under the Action “Investment Plans of Innovation“ in the Region of Central Macedonia, under the framework of the Operational Program “Central Macedonia 2014-2020.”
The Action aims to assist enterprises and research organizations in implementing research projects.
The use of carbon-free fuels in internal combustion engines is a very attractive solution in the direction of CO2 emissions reduction. In road transport, the use of hydrogen (H2) as a fuel in internal combustion engines is proposed as a clean fuel for LD/HD vehicles. At the same time, in the field of maritime transport and in line with the IMO’s proposed strategy for reducing CO2 emissions from ships, the use of ammonia (NH3) as a marine fuel will be adopted at increased rates.
In this investment plan, Exothermia SA intends to develop new simulation models and acquire know-how in the emerging area of zero-carbon engines. Specifically, the project aims to investigate the operation of H2 and NH3 fueled combustion engines with the respective de-NOx after-treatment systems using testing and modeling methods. The target is to develop a complete simulator to be used in the combined optimization of combustion and emissions after-treatment in on-road and marine applications.
Investment’s total budget is 399,430€ out of which 319,544€ is public expenditure. The Action is co-financed by Greece and the European Union – European Regional Development Fund.
The approved investment plan includes the following categories of investment:
- Staff costs
- Expenses of instruments & research equipment
- Expenditure on contract research, knowledge and patents
- Additional overheads and other operating expenses
- Expenditure on patents and other intangible assets
- Expenditure on the secondment of highly qualified staff to new posts created for the purpose of the project
Through its participation in the Action the company achieves:
- Development of synergies with research and academic institutions/companies
- Increasing competitiveness
- Transfer of know-how
- Production of new innovative products/services in the priority areas of the smart specialization strategy (RIS3)
- Enhancing extroversion
- Employment of highly qualified scientific staff
