DEFINITION

Classification: 204/170

(under subclass 168) Processes directed to the production of gaseous hydrocarbons.

(1) Note. This group of patents is intended to include processes for the production of heating and illuminating gaseous mixtures comprising hydrocarbons when use is made of an electrostatic field or electrical discharge for their preparation. However, those processes are not here included which employ an electrostatic field or electrical discharge as merely one of a series of treatments of hydrocarbons to produce such gases unless the other treatments are in nature of preparatory steps for the electrostatic field or electrical discharge step and are integrally associated therewith.
