Abstract: 711,366. Distilling oil shale. DALIN, D. July 25, 1051, No. 17661/51. Class 55 (1) In a process for distilling oil shale and like carbonaceous material, the shale is fed downwardly through vertical retort 13 comprising superposed preheating zones 11 and 12, a distillation zone 10 and a combustion zone for spent shale 5, the hot flue gases from the combustion zone 5 being used in heaters 49 and 36 respectively to heat a circulating gas which is passed through the distillation zone to distil the shale and air for the combustion zone, the thus heated air passing first through the shale preheating zone 11 and then partly to the combustion zone 5 and partly for recirculation. The flue gases after the heater 36 pass to the stack either through a line 28 or through a line 27, the preheating zone 12 and a line 31. Boiler tubes 17 and 56 are arranged adjacent to and in the combustion zone 5, water being fed thereto from a steam drum 15, which also feeds the water to tubes 22 which form the walls of the preheating zone 11 and steam to a superheater 20 arranged in the path of the hot flue gases from the zone 5 and adapted to feed superheated steam through tubes 19 which form the walls of the distillation zone to control the temperature in the distillation zone. Distillation products leave via a line 46 passing partly to purification and partly for recirculation through the heater 49 and the distillation zone. Flaps 55 and 39 control the admission and passage of air into the combustion zone 5 and through the preheating zone 11  respectively. The retort 13 is arranged centrally of a surrounding vessel dividing the vessel in conjunction with transverse walls into a series of inlet and outlet chambers 29, 30, 38, 40 and 52, 45, gases pass laterally through the material in the retort between the inlet and outlet chambers. In a modification the combustion zone may be of greater width than the remainder of the retort to increase the capacity of the apparatus. Specifications 647,051 and 647,119 are referred to.

Filed: 1967-04-19
Abstract: 1,199,803. Curable polyurethane compositions. UNION CARBIDE CORP. 19 April, 1967 [20 April, 1966], No. 17861/67. Headings C3P and C3R. [Also in Division B2] A curable composition comprises a solution in a monomeric ethylenically unsaturated compound of a polyurethane, the relative amount of the polymerizable ethylenic groups of the unsaturated compound per polymerizable ethylenic group of the polyurethane being 0À2 to 5, the monomeric ethylenically unsaturated compound containing no hydrogen atoms reactive with NCO groups and the polyurethane being the reaction product of a bis-(isocyanatoalkyl)- fumarate in which the alkyl group contains at least two carbon atoms and a cyclic diol at an isocyanate/hydroxyl ratio of at least one, the cyclic diol possessing (a) a non-aromatic cyclic nucleus which is carbocylic or heterocyclic containing 5 to 7 atoms therein, the heterocyclic nucleus containing no atoms other than C, O or N, (b) at least one monovalent hydrocarbon or acyloxy substituent monovalently bonded to the cyclic nucleus and (c) two alcoholic non- phenolic hydroxyl groups which may be monovalently bonded directly to the carbon atoms which form the cyclic nucleus or to a hydrocarbon radical (other than that referred to in b), which in turn is bonded to the cyclic nucleus. The bis-(isocyanatoalkyl) fumarates used are suitably those wherein the alkyl group contains 2 to 12 carbon atoms, especially bis-(2-isocyanatoethyl) fumarate. Exemplified cyclic diols are 4-(4-methyl-3-pentenyl)-3-cyclohexene-1,1- dimethanol; 4 - (4 - methyl pentyl) cyclohexane - 1,1 - dimethanol; linseed fatty acid derived - 2 - oxazoline - 4,4 - dimethanol; dehydrated castor fatty acid derived-2-oxazoline- 4,4-dimethanol; soya fatty acid monoester of tricyclo-[4.3. 1<SP>2,5</SP>0<SP>1,6</SP>]-decane-3 or 4,8,9-triol. Preferred monomeric ethylenically unsaturated compounds are diallyl phthalate, ethyl acrylate, styrene and methyl methacrylate, if desired, diluted with an inert solvent such as benzene, toluene, xylenes, butyl acetate or the monomethyl ether of ethylene glycol monoacetate. The isocyanate-hydroxyl reaction suitable takes place in the monomeric ethylenically unsaturated compound as solvent and in the presence of a catalyst for the NCO/OH reaction. Suitable such catalysts are tertiary amines and organometallic compounds. A vinyl polymerization inhibitor may be incorporated at this stage to prevent premature curing. The polymerization through the ethylenic bonds of the polyurethane and reactive solvent is achieved by the addition of vinyl polymerization catalysts, such as peroxides, azo compounds, persulphates, percarbonates, perborates and peracids. Metallic activators or accelerators may be added to the polyurethane solution prior to the addition of vinyl polymerization catalysts. The final cure involves a reaction between the free isocyanate groups (NCO : OH greater than one) and the moisture in the air.
