摘要:
Homogeneous amorphous aluminum phosphate composition with a surface of 100 to 300 m.sup.2 /g and a pore volume in pores with diameters of less than 1000 nm of at least 1.0 cm.sup.3 /g, in which phosphorus and aluminum are present in a molar ratio in the range from 0.9:1 to 1:1 and which is characterized in that it is present in the form of microspherical particles with a particle size of 10 to 20 .mu.m and displays a bimodal pore-size distribution in the pore-diameter range of less than 1000 nm. Also described is a process for the production of the novel aluminum phosphate composition, which is suitable in particular as a cracking catalyst, as a catalyst support, especially for polymerization catalysts, as a flatting agent, as an adsorption agent and as a thickening agent.
