Title: Improvements in or relating to method of synthesizing gasoline hydrocarbons
IPC: C07C1/06
Filed: 1948-01-20
Abstract: Carbon monoxide and hydrogen are catalytically reacted to produce liquid hydrocarbons, oxygenated compounds, and water, the oxygenated compounds being separated and a part thereof recycled to the reaction zone to increase the yield of hydrocarbons.  The product is preferably separated into a gas phase, a liquid hydrocarbon phase, and a water-phase, the last containing most of the low-boiling oxygenated compounds, the gas phase is recycled at least in part, the water phase extracted at elevated temperature and pressure with a hydrocarbon solvent to remove most of the non-acidic oxygenated compounds, the extract combined with the original liquid hydrocarbon phase, fractionated, and a substantial part of the fraction distilling below 245 DEG  F. recycled.  The rest of this fraction and the fraction boiling above 245 DEG  F. are treated to extract oxygenated compounds and give a hydrocarbon raffinate.  The synthesis may be effected with a fluidized iron catalyst.  The separation into three phases may be made at 200-300 DEG  F. and 150-300 pounds per square inch, which displaces part of the low-boiling oxygenated compounds from the aqueous to the hydrocarbon phase.  The aqueous phase may be extracted at 200 DEG  F. and 200-250 pounds per square inch with naphtha.  Ethyl alcohol and organic acids are the main constituents of the residual water-phase, the former being removed as aqueous azeotropes and recycled to the synthesis while the acids may be recovered by azeotropic distillation of the water with a hydrocarbon.  The hydrocarbon phases not recycled may be extracted with ethylene glycol to remove alcohols, aldehydes, ketones, and some esters.  Other solvents are polyolefin glycols, furfural, acetone or nitromethane.  The hydrocarbon raffinate is water-washed and fractionated to yield gasoline and diesel fractions.  Part may be used for the primary extraction of the water phase.  The glycol extract is fractionated to distil up to C7 alcohols, and aldehydes and ketones, while high-boiling alcohols &c. are recovered by steam distillation.  These may be hydrogenated, and the alcohols separated by fractionation. Oxygenated products boiling above 245 DEG  F. may be recycled to the synthesis or one specific type of product such as alcohols or even one alcohol such as ethanol only.  The Specification as open to inspection under Sect. 91 comprises the use of oxygenated compounds, such as alcohols, aldehydes, ketones, acids, and esters of up to 20 C atoms, from any extraneous source for addition to the reactants.  This subject-matter does not appear in the Specification as accepted.

Abstract: 228,177. Gebers, F. Jan. 22, 1924, [Convention date]. Screw propellers. - Partially immersed screw propellers have blades the leading edges of which project forwatdly in the plane of rotation, and the roots of which are supported at two places in the boss. The blades may be fitted with external pitch altering gear which is handcontrolled or automatically as by the engine governor. The pitch may increase from root to tip and from leading to following edge. The leading edge of the blade is inclined forwardly to make an' acute angle with the tangent to the outer blade circle., Fig. 1, and the tip of the leading edge may be formed with a scallop. Instead of the blade being attached directly to the boss, an intermediate arm may be employed. When the blades are rotatable on their axes, the root a is supported in the boss in two bearings, Fig. 8, and' may be radially or offset to the shaft axis. Each blade has an external arm b, Fig. 9, which is connected to a rod c on a sliding ring d, the latter being constrained to rotate with the boss by guide bolts e. The ring d is slidden by a non-rotating disc g which is moved axially by worm and worm gear i acting on two lower screws h. The control gear for a number of propellers may be jointly actuated.
