The subcritical hydrothermal treatment can be performed at a generally low temperature and followed by a second hydrothermal treatment at a higher temperature.

The product of the hydrothermal treatment is optionally subjected to a reduction treatment (including nitriding treatment).

More specifically, the invention is provided to improve hydrothermal stability of the catalyst through hydrothermal treatment of ceramic fabric carriers before washcoating.

The present invention relates to an apparatus for the continuous hydrothermal treatment of substances.

Step (1): subjecting a cellulose-containing biomass to a hydrothermal treatment and then separating the resultant solution into a hydrothermal treatment solution and a cellulose-containing solid material.

The required barbosalite may be made by the hydrothermal treatment of a solid that is predominantly ferric phosphate.

Refined organic liquid can be recycled into the hydrothermal treatment as the solvent.

The thin films possess a mesoporous structure which may be enhanced by means of a hydrothermal treatment.

High absorbency lyocell fibers are obtainable by hydrothermal treatment.

A process for the coating of glass microspheres with an aluminium hydroxide is described which comprises the hydrothermal treatment of a suspension of complexed Al3+-ions with glass microspheres.

The present invention further relates to a corresponding method of continuous hydrothermal treatment.

A method, apparatus and use for hydrothermal treatment of organic material.

The method does not involve a hydrothermal treatment step, hence avoiding the formation of zeolite crystals.

Within specific industrial processes it may be necessary that products have to be treated hydrothermally.
