A method for denitrification of water, in which the water to be denitrified is made to flow over a porous carrier which comprises a transition metal, preferably palladium, used in an amount between 0.01 and 5% by weight on the carrier and on which denitrifying bacterial strains capable of surviving in the presence of hydrogen are made to adhere, and in which hydrogen is used as a reducing agent and the pH of the reaction is adjusted to values of 4.5 to 7.8 preferably by using carbon dioxide.

Method for water denitrification

Catalysts for the fluid-bed hydrodechlorination of carbon tetrachloride to chloroform having high catalytic stability and comprising platinum supported on microspheroidal gamma alumina, characterized in that the platinum is in the form of particles dispersed throughout the mass of the support.

Catalysts for hydrodechlorination of carbon tetrachloride to chloroform

An ethylene oxychlorination catalyst in granular form, consisting of CuCl.sub.2 supported on an alumina carrier, displaying a cylindrical configuration with trilobed cross-section provided with three through-bores equidistant from each other, each of which through-bores has its axis parallel to the axis of the cylindrical granule.
