Title: Improvements in the purification of crude hydrocarbons or their derivatives
IPC: C10G17/09
Filed: 1930-05-17
Abstract: Crude hydrocarbons such as coke oven benzol, are purified by treatment with maleic acid or anhydride.  Crude benzol is refluxed with 1 to 3 per cent of maleic acid anhydride, and the purified oil is separated by distillation.  Further purification by treatment with sodium hydroxide or carbonate may be employed.  The process may be applied to hydrocarbons before or after the removal of sulphur compounds as described in Specifications 315,439, [Class 91, Oils &c.], and 333,511, [Class 1 (i), Chemical processes &c.].  The treatment removes such impurities as cyclo-pentadiene, butadiene, and heterocyclic compounds such as pyridine.  By crystallizing from benzene, the residue obtained from the purification of crude benzol, there is obtained methylene tetra hydro phthalic acid anhydride.  The residue may be esterified with a polyvalent alcohol such as glycerol to form a resin.ALSO:Crude hydrocarbons such as coke oven benzol are treated with maleic acid or anhydride, whereby impurities such as cyclopentadiene, butadiene, and heterocyclic bases such as pyridine, are removed.

Title: Improvements in autogenous coking of agglomerates of zinciferous and carbonaceous materials
IPC: C22B1/14
Filed: 1949-06-08
Abstract: 659,956. Agglomerating zinc ores. NEW JERSEY ZINC CO. June 8, 1949, No. 15293. Convention date, July 31, 1948. [Class 82(i)] [Also in Group XII] In a method of autogenously coking agglomerates of zinciferous material and carbonaceous material the said agglomerates are moved in a bed through a furnace in which coking conditions are established by radiant. transfer of heat to the bed from a combustion zone in which heat is provided by combustion of at least a portion of the volatile matter liberated from the said carbonaceous material by the coking thereof, the amount of heat transferred to the bed being insufficient to heat the agglomerates to a temperature in excess of 900‹C. Fig. 1 shows a furnace for carrying out the coking operation. Briquettes are fed to a hopper 13 provided with a grizzly 14 for separation of fines. Shoot 15 discharges the briquettes on to a travelling grate 11, under levelling bar 17, which carries them through the furnace to discharge hopper 18. Air is admitted under pressure from supply line 27 to valved branches in each of hoppers 22 permitting control of the air supplied to each part of the furnace to maintain a gentle, protective, candle-like flame about the briquettes in the moving bed and to ensure that the heat of combustion of the volatile matter consumed in the bed is insufficient to raise the temperature of the bed to the desired coking range. Air is introduced to the combustion zone above the bed through ports 30, the amount being so controlled as to effect combustion of that amount of volatile matter liberated from the bed required to bring the bed to an average coking temperature of about 800‹C., the hottest parts of the bed being at not over 900‹C. Waste gases from the zone are withdrawn through adjustable gates 24 to a secondary combustion zone where combustion is completed with air drawn in through ports 31. The burnt gases are withdrawn through pipe 25, a portion being branched off to line 35 below the charging hopper and used to dry the incoming charge by passage therethrough. Coking conditions should be such as to produce 0.4-1.2 tons of coked agglomerates per day per square foot of grate area in the coking zone. The coked agglomerates may be charged to a vertical retort heated to zinc smelting temperature and permitted to descend by gravity through the retort as the reduction proceeds with the liberation of zinc vapour. Specifications 533,988, [Group IV], and 563,037, [Group XII], and U.S.A. Specifications 1,810,070 and 1,835,460 are referred to.
