ABSTRACT: This review provides an overview of the recent

achievements in catalytic process development for alkyne hydrogenations. It underlines the necessity of simultaneous optimization

over different length scales from molecular/nanoscale of active

phase, up-to macro-scale of catalytic reactor design. One case

study, the hydrogenation of 2-methyl-3-butyn-2-ol, is analyzed in

detail to illustrate the practical application of this approach. Finally,

it presents the personal view of the authors concerning the new

trends and paths available in the field.

KEYWORDS: alkyne, hydrogenation, catalyst design, support effect, reactor design 1. INTRODUCTION

Sustainable processing with minimal environmental impact has

been recognized as one of the major challenges of this century.1

As a result of the severe restrictions in environmental

legislation, the chemical industry is now undergoing a

progressive redefinition. Catalytic technology, as a fundamental

tool for green chemistry, has an unprecedented enabling

potential for sustainable production. Heterogeneous catalysts

are of utmost importance in the fine chemical industry. The

typical design in these systems is based on an active phase, main

responsible for the catalytic performance (activity and

selectivity), immobilized on a suitable support. This avoids

agglomeration of the active species during chemical reaction

and enables an easy catalyst recovery. The conventional

methodology applied for catalyst optimization has been an

empirical "trial-and-error" approach which results, at best, in

slight or incremental improvements of their performance.

Moreover, it is greatly based on speculation and is, in practice,

laborious and time-consuming. With the concomitant advance

in theoretical understanding and the development of computational power, a new era of rational catalyst design (RCD) is

dawning.2 This approach is based on a multidisciplinary

combination of new advances in synthesis, characterization,

and modeling with the ultimate aim of predicting the catalyst's

behavior based on chemical composition, molecular structure,

and morphology.3
