ALTAD PROJECT

PROJECT TITLE

DEVELOPMENT OF ALTERNATIVE SYSTEM FOR THE SELECTIVE CATALYTIC REDUCTION OF NITROGEN OXIDES FROM DIESEL ENGINES.

ACRONYM

ALTAD

ABSTRACT

The main objective of this project is to develop and design a system for selective catalytic reduction of nitrogen oxides from diesel engines; more efficient and environmentally friendly than current systems based on Adblue®.

To do so, a prototype of an alternative device for selective catalytic reduction of NOx of diesel engines, based on the use of methanol is being developed; thus achieving a system with superior performance. The device will consist of a methanol reformer (produces hydrogen from methanol) and a catalyst device SCR-H2, able to remove NOx emissions from diesel engine exhaust fumes .

DETAILED PROJECT DEVELOPMENT

FIRST SEMESTER

The Life-Cycle Assessment (LCA) of traditional after-treatment systems (AdBlue® based) and the new system (to be developed) are performed.

Development of a methanol reformer catalyst:

Objective: Design and prepare stable and efficient catalysts to produce H2 from methanol.

SECOND SEMESTER

Simulation models are made to predict the effectiveness of the new after-treatment system. At the same time, emission measurement tests are performed on the engine bench with the traditional system after-treatment (AdBlue®).

Prototype development subsystem:

Objective: Integrate catalysts developed in the prototype.

THIRD SEMESTER

Both the mechanical design and the electronic control design of the new after-treatment system are made.

Prototype development subsystem:

Objective: Integrate catalysts developed in the prototype.

SCR catalysts-H2 Development

FOURTH SEMESTER

Mechanical integration of the new after-treatment system with the combustion engine is performed, and the control electronics start. Trials begin on the engine bench with the new system.

Prototype development subsystem:

Objective: Integration of catalysts developed in the prototype.
