Description
Patented May 19, 193i V UNITED STATES? PATENT oFHc ensrAv nenorr Ann HARRY r. BENNER, or. onIcAeo, ILLINOIS, ASSIGNORS r0 UNIVERSAL on. PRODUCTS COMPANY, or oHIcAGo, ILLINOIS, A CORPORATION or SOUTH DAKOTA I PROCESS FOR CRACKING HYDBOGARLBON'PRODUCTS No Drawing. Application filed April 25, 1921,.Seria1 No. 464,367. Renewed lTuly 2, 1928.
This invention relates to cracked hydro carbon products and process of producing" as to convert substantial percentages thereof into light hydrocarbons as, for example, gasoline or gasoline-like bodies.
The invention will be more clearly understood from the description of the process as carried out by us and hereinafter fully set forth.
For example, a wax oil, resulting from the atmospheric distillation of a Mexicancrude oil of substantially 20 Baum gravity, in accordance with our process, is subjected to pressure distillation under an initial pressure of 350 pounds per square inch and a liquid temperature of 820 R, which pressure :is gradually reduced down to 80 pounds per square inch and which temperature is increased to a liquid temperature of v887 F. By carrying out the process under such conditions of'ternperature and pressure,a pressure distillate equal to 60 per cent of the oil charge may be recovered, having an average Baum gravity of 50. The pressure distillate,-upon redistillation, produces 7 5 per cent gasoline, having an initial end point of 103 R, an end point of 428 F., a Baum gravity of 57.7
is gradually reduced from 350 to 80 pounds per square inch, while the temperature is the oil ranges from 820 F. to 887 F. and the vapor temperature from a minimum of 783 F.to a maximum of 890 F.
When subjected to redistillation, 80 per cent of the gasoline produced boils below 350 F. and the same has a light, straw color. The residuum, upon retreatment, yields 27.9 per cent coke,.while 70 per cent of the residuum boils below 820 F.
From the foregoing, it will'be seen that our process permits of the recovery of a very substantial yield of gasoline from a wax oil by subjecting the same to pressure distillation under a gradually decreasing pressure.
We claim as ourinv'ention A process for cracking wax oil, consisting in introducing a body-of oil to a still, in maintaining said oil while undergoing distillation in the still under a gradually decreasing self imposed vapor pressure ranging from a maximum of at'least 350 poundsper square inch, and in increasing the temperature substantially as the pressure on the oil is decreased.

and an unsaturated hydrocarbon content of 15 A per cent. Calculated upon the basis of the" process, 35 per cent of the still charge may be recovered as pressure distillate per hour. More specifically, the Mexican Wax oil treated had a Baum gravity of 19.6 and I initial boiling point of 298 F., while 95 per.
cent ofthe oil boiled'below 7 85 F.'3I1d. con-. tained 64 per cent" unsaturates. This oil, when treated in accordance with our process, can be ma'detoyield per cent pressure distillate,33.5 per cent residuum, with a carbon. and gas production of only 6.5 per cent'of the oil charge.
As above pointed out, the pressure on the oil
