Abstract: Preparation of a fermented sludge for use as an animal feed additive which contains a fermentation product, comprises granulation, compaction and drying of the sludge in a fluidised bed, at the same time as introducing extra mechanical energy above that needed to fluidise the bed particles, in order to achieve the desired additive particle size and bulk weight.

Abstract: Coated particles of sodium percarbonate consisting of a core of sodium percarbonate made by crystallisation in the aqueous phase and a two-layer coating adhering to and enveloping the core, applied by spraying in a whirling bed, in which the innermost layer consists essentially of Na percarbonate and the outer layer consists essentially of Na sulphate which may be partially hydrated.

Abstract: A method for the production of granulated alkali metal and alkaline earth metal cyanides by fluid bed granulation comprises spraying a solution or suspension of the cyanide onto a fluidised bed of the cyanide nuclei. The water is evaporated using a stream of super-heated water vapour introduced at a temperature of 150 - 500 degrees C, the bed temperature being 110-350 degrees C.

Abstract: Reducing or preventing foaming in chemical and physical transformation processes in liquid media comprises carrying out the transformation in a buoyancy-free jet reactor with no baffles, which has a tapered lower part and is fitted with a gas injector in a position which facilitates circulation without buoyancy. The reactor contents are thoroughly mixed by gas injection. Also claimed is an apparatus for the above process, with a pipe connection for taking off a high-solids suspension and an inlet tube for a liquid medium above the gas injector, the outlet of this tube being located in the cloud of bubbles formed when the apparatus is working.

Abstract: An ammoxidizable compound is reacted with an ammonium salt, especially an inorganic ammonium salt, in the presence of a source of oxygen and an ammoxidation catalyst at 100 to 700 DEG C., preferably 200 to 700 DEG C., in order to produce cyano compounds of the formula R-CN, in which R is H or an organic group.
