摘要： A process is described for producing humic acids by coal oxidation effected in the dry phase with oxygen or an oxygen-nitrogen mixture in a fluidized bed reactor using coal of up to 3 mm particle size and operating at a temperature of between 150 and 300°C at a partial oxygen feed pressure of between 0.7 and 5 ata, at a total pressure not exceeding 40 ata and for a contact time of between 30 and 600 minutes, characterised by recycling part of the exit gases from the reactor back to the reactor after cooling them to a temperature of between 50 and 100°C.

摘要： Process for preparing regenerated humic acids from coal by means of the continuous oxidation on fluidized bed, characterized in that a coal of lignite, sub-bituminous or bituminous type is submitted to a preliminary oxidation under mild conditions in order to reduce the hydrogen content of said coal by an amount of 5 to 25% of hydrogen initially present in the starting coal, and that the resulting coal is subsequently submitted to an oxidation in order to produce the desired humic acids.
