Abstract
A process for the preparation of an amorphous mesoporous and macroporous alumina: at least once dissolving an acidic precursor of aluminium, adjusting pH by adding at least one basic precursor to the suspension obtained in a), co-precipitation of the suspension obtained from b) by adding at least one basic precursor and at least one acidic precursor to the suspension, filtration, drying, shaping and heat treatment. An amorphous mesoporous and macroporous alumina with bimodal pore structure:
