BASF HF-200
Smooth, Spherical Alumina
BASF HF-200 alumina is a smooth, spherical alumina which has demonstrated its value in removing free HF and organic fluorides from HF alkylation product streams.
Both propane and butane streams from the HF alkylation process are treated to remove fluorides to meet product specifications.
The mechanism of fluoride removal involves both adsorption and chemical reaction on the alumina. Organic fluorides and HF adsorb on the alumina. The organic fluorides react to form olefins and HF. HF reacts with the alumina, forming AlF3. The high surface area and pore size distribution of BASF HF-200 alumina is designed to optimize the entire adsorption-reaction-conversion performance.
The excellent physical strength of BASF HF-200 remains throughout the life of the alumina. The low abrasion loss and low silica content contribute to longer service life and minimized plugging of valves due to alumina fines and SiF4 formation.
