SYNTHESIS, CHARACTERISATION AND EVALUATION OF MULTI-LAYERED AND PILLARED MATERIALS FOR PROCESS CHEMISTRY AND THE ENVIRONMENT

Objective


Processes for the reproducible and predictable preparation of pillared layered and multi-layered materials with regular interlayer spacings were developed. Three different types of layered materials were studied, namely pillared and layered clays, zirconium phosphates and phosphonates and layered double hydroxides. Many novel materials were synthesised and characterised. The successful laboratory syntheses were refined and, for representative materials, scaled up to produce several kilograms per batch.

Materials were tested for catalytic behaviour towards a range of industrially important processes including the etherification of olefins, catalytic cracking, isobutane alkylation, ethylene hydration and glycol ether synthesis. Clay based catalyses performed very well for the production of the gasoline components MTBE and TAME, whilst chromium-copper based LDH's pillared with vanadate or molybdate polyoxomettalate anions have been found to be very selective catalysts for the synthesis of glycol ethers.
The project will develop processes for the preparation of pillared layered structures and multi-layered materials of regular interlayer spacings, having desirable and predictable chemical properties. If successful this will generate several materials with a wide range of possible applications, including improved chemical synthesis and environmental protection.

Materials will initially be prepared as powders or pellets by different methods in each laboratory and tested using an agreed range of reactions and characterization techniques, while successful materials will be scaled-up for further testing. The work will be divided into five tasks covering the preparation and selection of materials, evaluation, characterization and optimization of active site, scale-up of preparations, the assessment of performance at the laboratory pilot scale and project management.SP 1 2
