Abstract
Abstract This process, in which gas bubbles are formed in the electrolyte, is carried out in electrolytic cells which are non-partitioned or partitioned by at least one separator and in which at least one electrode is perforated. For this purpose, the electrolyte is caused to flow by means of gravity through the electrolytic cell in such a manner that a gas space is formed laterally to the main direction of flow of the electrolyte, both electrodes or the separators or one separator and the perforated electrode being wetted.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
74 words
A process for the electrolysis of liquid electrolytes in which gas bubbles are formed in the electrolyte, in electrolytic cells which are non-partitioned or partitioned by at least one separator and in which at least one electrode is perforated, which comprises causing the electrolyte to flow by means of gravity through the electrolytic cell in such a manner that a gas space is formed laterally to the main direction of flow of the electrolyte.
Claim 2
Dependent Claim
74 words
A process for the electrolysis of liquid electrolytes in which gas bubbles are formed in the electrolyte, in electrolytic cells which are non-partitioned or partitioned by at least one separator and in which at least one electrode is perforated, which comprises causing the electrolyte to flow by means of gravity through the electrolytic cell in such a manner that a gas space is formed laterally to the main direction of flow of the electrolyte.
Claim 3
Dependent Claim
27 words
The process as claimed in claim 1, including two electrodes and wherein the electrolyte is caused to flow in such a manner that both electrodes are wetted.
Claim 4
Dependent Claim
27 words
The process as claimed in claim 1, wherein the electrolyte is caused to flow in such a manner that the perforated electrode and a separator are wetted.
Claim 5
Dependent Claim
23 words
The process as claimed in claim 1, wherein the electrolyte is caused to flow in such a manner that the separators are wetted.
Claim 6
Dependent Claim
20 words
The process as claimed in claim 1, wherein the electrolyte is caused to flow at least partially through the separator.
Claim 7
Dependent Claim
24 words
The process as claimed in claim 1, wherein the electrolyte is caused to flow in such a manner that it is reversed several times.
Claim 8
Dependent Claim
20 words
The process as claimed in claim 1, wherein the electrolyte is caused to flow in several channels side by side.
Claim 9
Dependent Claim
18 words
The process as claimed in claim 1, wherein the electrolyte is deflected and flows in a meandering pattern.
