Abstract: A syntactic foam and water-based explosive comprising glass microbubbles formed by heating feed having a size distribution with a span of less than 0.9 that are dispersed in a polymeric matrix or emulsion explosive. A method for making glass microbubbles, syntactic foam and water-based explosives is described.

Abstract: Methanol is produced by gasifying a carbonaceous feed material with steam in the presence of a carbon-alkali metal catalyst and added hydrogen and carbon monoxide at a temperature between about 1000.degree. F. and about 1500.degree. F.

Abstract: A process for the separation of carbon dioxide and other acid gas components, in a compound distillation column, from a gaseous mixture comprised of one or more hydrocarbons, inclusive of methane, and hydrogen. The compound distillation column is sectioned (or zoned), one section of which is operated at higher pressure than another, and hence in a relative sense is referred to as a high pressure section while the other is referred to as a low pressure section. A product, principally methane, is removed from the high pressure section while a product of principally acid gases is removed from the low pressure section. By maintaining the sections at different pressure, the separations are more efficiently made and phase separation of products in the low pressure section is easily maintained.

Abstract: A high purity chemical synthesis gas is produced by reacting steam with a carbonaceous feed material in the presence of a carbon-alkali metal catalyst and substantially equilibrium quantities of added hydrogen and carbon monoxide at a temperature between about 1000.degree. F. and about 1500.degree. F.

Abstract: A process for the separation of carbon dioxide and, optionally, other acid gas components in a distillation column, operated at high pressure and low temperature, from a gaseous mixture comprising one or more hydrocarbons, including particularly methane, and hydrogen. In its preferred aspects, the feed is predominantly methane, suitably from about 30 to about 85 mole percent and preferably from about 50 to about 80 mole percent methane. The concentration of hydrogen in the gaseous mixture will be sufficient to provide from about 6 to about 34 mole percent, preferably from about 15 to about 25 mole percent hydrogen in the rectification portion of the distillation column. The separation can be effected in a single column usually having from about 20 to about 30 theoretical distillation stages and the feed can be one constituted ab initio within the desired ranges of composition, or modified by addition of components just prior to or at the time of distillation.

Abstract: A game board depicting a land area of natural features and man-made objects surrounded by a border of spaces representing knowledge areas, said land area divided into paths of squares over which the movement of game pieces is directed by chance and by choice of the players.A set of preferred rules which stress hunting safety and teach the sport of hunting to the novice while simultaneously provided challenge to the experienced hunter.A plurality of game pieces representing bird and animal wildlife and game pieces representing the players (hunters).A plurality of cards representing hunting equipment which determine the wildlife to be hunted and accessory equipment to accompany the hunter.A plurality of cards representing hunting situations which vary the progress of the play.A die which provides chance movement and selection of cards during the play.

Abstract: Subdivided carbonaceous feed solids containing volatilizable hydrocarbons are hydrogasified by heating the solids to at least minimum hydrogasification temperature while in dilute phase suspension in a gas containing molecular hydrogen and in contact with subdivided hot solids having a temperature greater than minimum hydrogasification temperature. The feed and hot solids are passed with the hydrogen-containing gas through a transfer line hydrogasification zone having a length which, for the velocity of the solids passage therethrough, limits the residence of the solids therein to the time necessary for devolatilization of the carbonaceous feed solids and for conversion of a predetermined minor proportion of the carbon of the feed solids to methane. Suitably from about one to about 50 mol percent of the carbon in the carbonaceous feed solids is converted to methane.
