Low temperature VOC combustion over manganese, cobalt and zinc AlPO{sub 4} molecular sieves. Semi-annual report-1, September 1, 1995--February 29, 1996

The objective of this project is to prepare manganese, cobalt and zinc containing AlPO{sub 4} large pore molecular sieves of structure type -36 and evaluate their ability to function as successful oxidation catalysts for the removal of low levels of VOC`s from gas streams. The tasks to be accomplished are as follows: (1) To develop reliable synthesis methods that produce the large pore metal aluminophosphates containing manganese, cobalt and zinc in their framework. (2) To characterize these materials to determine phase purity and the location of the incorporated metal in the framework. Characterization will also include the nature of the active sites within the structures and the effect manganese, cobalt and zinc has on the structures` acidity. (3) To screen the material for their catalytic activity in the oxidation of hydrocarbons and aromatics. This report gives a summary of the status of the project as of 28th February 1996
