Title: Improvements in the manufacture and production of lubricating oils
IPC: C10G21/06
Filed: 1933-10-30
Abstract: Lubricating-oils are obtained by: (1) converting coal, peat, or other solid carbonaceous materials into liquid products, e.g. by extraction, low - temperature carbonization, destructive-hydrogenation, or coking, followed or not by cracking or destructive-hydrogenation; (2) topping the liquid products to 350 DEG C., and purifying the residue or fractions containing such residue at elevated temperatures by alcoholic solutions of caustic alkalies or other alkaline reagents; and (3) treating the purified products with selective solvents mixed or not with active carbon or bleaching earths.  The oils may then be improved by removing paraffin wax and/or adding agents lowering the setting point. When the 350 DEG  C. residues contain large proportions of asphalt or resin these impurities are preferably removed by precipitants or extraction agents, e.g. benzine, illuminating oils, and liquefied gaseous hydrocarbons, before treatment with alcoholic alkali. Selective solvents specified are phenols, liquid sulphur dioxide, liquefied gaseous hydrocarbons, aniline, acetone or other ketones, keto-acids, e.g. levulinic acid.  The conversion of the coal or peat into liquid products may be effected by extraction with such solvents as benzine, benzene, middle oils, heavy oils, pyridine, or halogenated hydrocarbons, mixed or not with alcohol or ether, and advantageously under pressure and at 50--500 DEG  C.; or by destructive hydrogenation at 350--600 DEG  C.; the tarry product is then distilled to 300, 325, or 350 DEG  C.  In an example, finely ground lignite is treated with dilute sulphuric acid to neutralize basic constituents, impregnated with ammonium molybdate, made into a paste with lubricating oil, treated with hydrogen at 200 atmos. and 475 DEG C., and the mainly liquid products are distilled up to 350 DEG  C. 1000 gms. of the residue is boiled under reflux with a solution of 100 gm. of caustic potash in 300 c.c. of ethyl alcohol, and allowed to stand; the refined oil is separated, washed with 5 per cent sulphuric acid, and treated 3 times with equal amounts of phenol at 50 DEG  C.  The product is freed from phenol by distillation, and from paraffin wax by diluting and cooling.

Title: Improvements in and relating to separators for gaseous substances, dust collectors, spark arrestors, dust extractors and the like
IPC: B04C3/00
Filed: 1920-11-01
Abstract: 172,838. Morris, F. Nov. 1, 1920. Density separa - tors.- In separators for gaseous s u b - stances, dust-extractors, spark-arresters, &c., the mixture of gas and suspended particles enters the chamber by a helic a 1 path and is caused to leave the helical portion as far from the axis as possible. The casing a has a truncated conical tube g secured over an opening d for the admission of gas. A central core j is placed inside the tube as shown and helical vanes h are secured between the cone and tube. Another cone k may be attached to the cone j. A tube l is secured to the casing over an opening e immediately opposite the opening d; the diameter of the tube is smaller than the diameter of the adjacent end of the conical tube g. The gas is drawn into the apparatus through the opening d, is given a rotary motion by the vanes h, and is forced away from the axis by the cone j. When it emerges from the tube g, the dust or other suspended matter passes into the chamber r and the clean gas passes out through the tube l. The dust collects in a rotary valve m at the bottom of the casing and is discharged by turning the valve. The cones j, k may be replaced by tubes passing through the tubes g, l and carrying a rod to keep the parts in their proper positions. In this case the vanes h are given an inclination and shape to throw the gas away from the axis. In a modification, the conical tube g is secured to a cylindrical inlet tube instead of directly to the casing. In another modification, two stays are provided as shown in Fig. 8, the first separation occurring in the chamber y and the second in the chamber r. The discharge valve may have a number of chambers which discharge through an orifice in the casing. Another modification is adapted for use in a locomotive type of funnel, and baffle-plates cause the separated cinders to pass into ducts leading to discharge valves. The Provisional Specification states that the dust may be collected in chambers which communicate with the lower part of the casing by means of slides and traps, and may be removed through a door in the lower part.
