Abstract:
A process for treatment of a lignocellulosic material comprising contacting the lignocellulosic material with a solution of chloride ions, which solution comprises a concentration of chloride ions in the range from equal to or more than 1 ppm weight to equal to or less than 350 ppm weight based on the total weight of the solution; at a temperature in the range from equal to or more than 120°C to equal to or less than 200°C; and at a pH in the range from equal to or more than 0.1 to equal to or less than 4.
Abstract:
The invention relates to a method for applying a cermet electrode layer to a sintered electrolyte. This layer consists of a mixture of an ion-conducting oxide and a semiprecious metal oxide or precious metal oxide. According to the invention, the ion-conducting oxide is calcined without the presence of the (semi)precious metal oxide in order to provide for lateral electron conductivity, while the sintering of the mixture on the electrolyte takes place at as low a temperature as possible.
Abstract:
The invention relates to a laboratory degradation test system for testing degradation of a test specimen in a test fluid flow, the test system comprising: - a reactor assembly, which reactor assembly comprises: - a reactor vessel, the reactor vessel having a reaction space, an inlet and an outlet and a specimen holder for retaining a test specimen inside the reactor vessel, - a heater for heating the reactor vessel, - a fluid circulation system generating a test fluid flow over the test specimen, which fluid circulation system comprises: - a circulation line which extends between the outlet of the reactor vessel and the inlet of the reactor vessel, which circulation line is arranged outside the reactor vessel, - a pump for providing fluid circulation through the circulation line and the reactor vessel, which pump is arranged in the circulation line. The laboratory test system according to the invention is characterised in that the volume available to the test fluid inside the reaction space after insertion of the degradation test specimen is less than or equal to 10 ml.
