Hydrogen - Fuel cell :

Osmosys, micro-CHP for individual houses program

IRMA starts a new collaborative program "Osmosys" on micro-CHP for individual houses operating with natural gas.

The concept is based on natural gas steam reforming to produce a hydrogen-rich reformate. The reformer, with various catalytic steps, is developed and built by IRMA in collaboration with the engineering company Syngas (44). The reformer is coupled to a high temperature PEM fuel cell.

The target : to produce electricity and heat with very high electric efficiency ( ~ 38 %).
Power ~ 1 KW electric.

IRMA is developing the reformer, the stack is provided by the Danish company Serenergy and Auer, a heaters manufacturer from Picardy, is the integrator and manufacturer of the complete system. This CHP-system will be characterized by EIFER in Karlsruhe (EDF in Germany). ICGM Institute in Montpellier will be in charge of membranes fundamental studies.

"Osmosys" has industrial objectives. It is part of the decentralization of power generation. This technology is already highly developed in Japan : more than 15,000 units are already in operation (photo: Program ENE.FARM Japan).

The program will end in March 2014.
Funding : DGCIS and Regional Council of Brittany.

Non-Road Mobile machinery, ships :

IRMA has developed a highly efficient catalyst for the nitrogen oxides (NOx) catalytic reduction by ethanol

This study was included in the cooperative program “REDNOx”, about the NOx catalytic reduction by hydrocarbons for automotive exhaust treatment (coordinated by PSA Peugeot Citroën). PSA and IRMA have jointly patented a catalyst for this application in 2011. IRMA has the exclusivity for non automotive uses.
IRMA is looking for an industrial partner for the catalyst and technology development on the “Off Road” market, which is subject to new regulations.
Diesel engines installed on mobile machinery (NRMM) significantly contribute to air pollution with various emissions: unburned hydrocarbons (HC), nitrogen oxide (NOx) and particulates. According to UE environmental policy, the objective is to gradually reduce these emissions and to remove polluting equipments. Then, these new emissions limits must be strictly respected by NRMM manufacturers in order to market them.
Since 1st January 2011 ships are also concerned by new NOx emissions regulations. These rules concern the ships of 61 states, which have ratified Annex VI of the International Convention for the Prevention of Pollution from ships (MARPOL Convention) of the International Maritime Organization (IMO). This new regulation requires a NOx abatement about 20%, compared with previous standard (and 80% from 1st January 2016).

NOx reduction :

Improve your DéNOx catalyst

Urea or ammonia Selective catalytic reduction (SCR) is the most common technique for the NOx emissions treatment.

It covers many areas and more generally stationary combustion sources : incinerators, electricity production units from fossil fuels, glass, cement ...

These units are subject to operating permit and regulation applies particularly for nitrogen oxides (NOx) emissions.

It is essential for their operators to know the DeNOx process and the intrinsic catalysts activity to predict, among other interventions to respect the standards.

Catalysts activity decrease over time. Their lifetime is normally indicated by the suppliers. Sometimes the evolution is due to dust or poisons deposition, which are difficult to anticipate or estimate.

IRMA offers its expertise to estimate the catalysts level activity (with a sample) compared to a new product, by a standard catalytic test.

IRMA uses physico-chemical means in order to make catalysts analysis : evolution study of various parameters (specific surface area, porosity, XRD), identification of potential deposits (SEM, EDAX, ICP), these datas are correlate with a loss of activity observed or suspected.

This offer allows operators to conduct their business intelligence tool providing the information necessary for decision making (changing the catalyst loading, regeneration, modification of temperature ...). IRMA also offers its expertise in regeneration solutions.

Greenhouse gas: N2O

IRMA develop a catalyst for nitric acid plants

IRMA has developed, together with GPN, a catalyst for N2O decomposition, a greenhouse gas which has a global warming potential 310 times that of CO2.

IRMA has a first industrial reference with this catalyst 10 years ago, at Clariant S.A plant, on a glyoxal synthesis unit.

The greenhouse gas reduction is equivalent to about 3 million tons of CO2.

This catalyst has been recently installed by GPN on tail gas treatment in a new GPN nitric acid plant (Capacity of 1 500 tons HNO3 per day) on Grand Quevilly site.
This unit starts in July 2009.

GPN has presented, at the ANNA conference at Little Rock USA in October 2009, the efficiency of this catalyst on N2O abatement formed on platinum gauzes dedicated to NH3 oxidation in NO.

As shown on the following curve (N2O abatement versus time), the results obtained are excellent (dowload document).

Nitric acid units are the major industrial N2O emitters. GPN is one of the first licence provider for this process.

With our partner, GPN, we hope to develop this catalyst at a worldwide scale.

IRMA carry on its work on a high temperature N2O decomposition catalyst which offers an alternative after platinum gauzes to N2O tail gas treatment as described above.

Ademe has provided financial support to all of this work.

Hydrogen and fuel cell :

1 kW prototype

The aim of GEN-BOX program (validated by PAN'H in 2007 and funded by ANR), which ends in November, is to develop and design small autonomous multifuel units (NG, propane, LPG, ethanol) for electricity production based on the concept involving a reformer and a high temperature PEM fuel cell.

Partners of this program :
- SNECMA : coordination, PEM fuel cell (HT) designer and supplier
- IRMA : reformer design with Syngas collaboration
- AUER : manufacturer

- IRC Lyon : ethanol reforming
- LMM : car potential benefits
