APPARATUS FOR cAirALYsIs.
Specification of Letters Patent.
Application filed June 24, 1918, Serial No. 241,652. Renewed June 5, 1919. Serial No. 302,045.
ment in Apparatus for Catal sis, and do hereby declare that the following is a full, clear, and exact description thereof.
My invention relates particularly to an apparatus for use in the production of aldetreat large quantities of .the alcohol.
hydes from alcohols.
The object of my invention is to provide a catalyzer apparatus of an advantageous character, by means of which a catalytic agent, as for example finely divided copper, may be effectively applied to alcohols to produce aldehydes, as for example in the production of acetaldehyde from ethyl alcohol, and in such a manner that the necessary temperature may be effectively maintained throughout all portions of the catalyzer.
A further object is to provide an appa-.
ratus of this character which is so arranged that the necessary temperature will be applied throughout all portions of the catalyzer, while at the same time the capacity of the apparatus is made sufficiently large Bto y meansv of my invention I am able, therefore, to avoid the disadvantages of other types of catalyzer a paratus in which the catalyzer was ine ectively or unevenly heated when large quantities of the catalyzer were being used to treat correspondingly large quantities of the alcohol, or in which it was necessary to provide the apparatus with only a small capacity if the catalyzer was effectively and uniformly heated.
Further objects of my invention will appear from the detailed description thereof contained hereinafter.
While my invention is capable of embodiment in many different forms, for the purpose of illustration I have shown only one form of the same in the accompanying drawing, in whichv The figure is a vertical section of an apparatus made in accordance with my invention.
In the drawing, I have shown a cylindrical casing 1, having an asbestos lining 2 for insulation, provided with a body of catalytic material 3. The body of catalytic material 3 may be comprised of granular carbon, as for example charcoal, treated so as to carry throughout the body thereof finely divided nitrate.
reduced copper... This catalytic material may be treated to form the finely divided reduced catal tic metal, such for example, as copper, nic e1, chromium or iron, thereon. As an exampleof this treatment, the carrier such as charcoal maybe impregnated with Patented Nov. 8, 1921.
the nitrate of the metal, the metal precipitated with ammonia, and the mass dried and ignited and then reduced with hydrogen at about 300 degrees C. for several hours. As a' result of this process a finely divided catalytic metal is produced on the carrier and the metal is in highly porous condition due to the volatilization of the ammonium The reduction takes place preferably in a copper tube. y In order to retain the bod of catalytic material 3 in place, an insulated perforated copper plate 4: is as shown provided at the lower end of the container 1, below which there is located a cover 5, having an inlet pipe 6 for alcohol vapors. At the upper portion of the container 1, a perforated copper plate 7 preferably retains the body of catalytic material 3 in place. The copper plates 4 and 7 are connected, respectively, to leads 8 and 9, located in an electric heating circuit, and the plate 7 is adapted to be adjusted by means of an insulating screw 10, passing through a cover 11 at the top of the container 1, so as to adjust the resistance to the passage of the electric current through the carbon particles of the catalytic material 3, and so as thus to adjust the temperature within the container 1. The vapors of acetaldehyde are conveyed away by means of a pipe 12 located in the cover 11. H
In the operation of my apparatus, the vapors of an alcohol, such for example as ethyl alcohol, are conveyed into the catalyzer apparatus by means of the pipe 6, and said vapors, as'well as the catalytic material, are maintained at the desired temperature of between 250 and 350 C. by the passage of the electric current through the carbon particles comprising the catalytic material 3 and the temperature of which is adjusted by adjusting the screw 10 to adjust the pressure exerted between said carbon particles. The acetaldehyde and hydrogen formed from the alcohol will be conveyed away by the pipe 12, and may be separated in any suitable manner.
In this way a large volume of alcohol vapors may be effectively treated in the appagranular material 'the passage of the ratus, while at the same time the action of the catalytic material willbe uniform, in-
asmuch as said material will be uniformly 1. In combination, a body of catalytic material in the form of a granular conductor of electricity, means for passing a current of electricity through the same -to maintain the catalyzer at an elevated temperature, and means for varying the resistance of the to the passage of the electric current.
2. In combination, a body of catalytic material comprising granular carbon, means for passing a current of electricity through the same to maintain the catalyzer at an elevated temperature, and means for varying the resistance of the granular material to electric current.
