Abstract
865,455. Treating gases with discharges. ELEKTROPHYSIKALISCHE ANSTALT B. BERGHAUS. July 15, 1957 [July 14, 1956], No. 22314/57. Class 39(1). In a method of carrying out chemical reactions on gaseous, vaporous or finely dispersed substances, in which the substances are injected as a jet into a vessel 2 through a nozzle 8 and in which the substances are removed from the vessel by means of a pump 29 so that a non-homogeneous gas pressure zone is established within the vessel, a glow discharge is set up in the non-homogeneous pressure zone between an apertured cathode and an apertured anode through which the substances pass. The cathode and the anode are insulated from the gas outlet 27. The nozzle 8 may act as the cathode and one or more ring electrodes 15a, 15b, 15c as the anode, or the electrode 15a as the cathode and electrodes 15b, 15c as anodes. The nozzle 8 may act as an anode with electrode 15a as the cathode. Ring electrode 15a may be replaced by a cylinder. It is stated that the glow discharge moves away from the nozzle in the direction of the jet. A direct, direct intermittent or low or high frequency discharge may be utilized. Several nozzles may be provided associated with separate anodes or with a common anode. The gas may be injected at an angle to or normal to the glow discharge. The gas pressure within the vessel is preferably at 1 to 10 mm. Hg., but may be above 20 mm. Hg. or above 50 mm. Hg. The gas is preferably injected at a velocity greater than 1/10th of the velocity of sound and the ratio of the gas pressure in the nozzle to the gas pressure in the vessel is preferably in the ratio of between 100:1 and 10:1. The nozzle and vessel are preferably cooled and the substances entering the vessel may be preheated or heated at the nozzle if the nozzle is at a higher temperature. A starting-up procedure is described in which an inert gas is introduced into the vessel and the glow discharge established.
