Sulphuric acid-urea composition resulting from the reaction of urea with a sulphuric acid sludge of petroleum origin, method of preparation and use as a fertiliser source.

摘要

Sulphuric acid/urea composition formed by the product resulting from the action of urea on a sludge of petroleum origin containing, by weight, from 50 to 99% of sulphuric acid and from 1 to 20% of organic residues. The acidic sludge can contain water and often arises from an alkylation reaction. This composition can be used as a fertiliser source or as a component of a fertilising formulation.
