Abstract
Fuel reformulation has been seeded by the growing consciousness of the potential damages mankind was causing to the
ecosystem and to itself. Fuel reformulation means that fuels are defined on a chemical composition base with additional
engine-technology related standards rather than on pure performance bases. These standards, which are getting more and
more stringent, can be met by different leverages, mainly catalysts and processes operating conditions.
This survey reviews the contribution of catalytic materials to the production of cleaner fuel components through some
significant examples selected from scientific and technical literature. Having described the trends in automotive fuels quality,
production of gasoline and diesel pool components is discussed relating the required properties to the material active site
configuration, i.e. acidity/basicity, structural parameters, physical constraints. While distinctions are made between pathways
leading to gasoline and those leading to diesel, sulfur removal is faced on a more generalized approach.

1. Introduction
As a consequence of the growing awareness of
mankind to the potential damage to the earth’s ecosystem,
a fuel revolution is taking place: “reformulated
fuels” are defined on a chemical composition base
with additional performance standards rather than on
a behavior base.
The energy history has experienced the introduction
of fossil fuels in the last couple of centuries causing
a continuously growing release of contaminants
to the atmosphere. Their nature and effects are different
and we can divide them into toxic and non-toxic
