Abstract:
Sulfur-linked bis alkylthio alkylimino N-alkyl carbamate pesticides can be stabilized against thermal decomposition induced and accelerated by a variety of contaminants by incorporation of a substantially non-alkaline inorganic compound, containing at least two oxygen atoms bound to a multivalent cationic atom. Thermally stable wettable powder, dispersible granular and liquid formulations of these pesticides can be prepared.
Abstract:
A method of systematically controlling endoparasites and ectoparasites of warm-blooded animals by orally or percutaneously administering to the animal a parasiticidally effective amount of an acyl urea compound.
Abstract:
An insulation system, and method of fabricating insulating means, comprising insulating material having good heat transfer resistance at pressures between 1 and 500 microns of mercury, and hydrophobic molecular sieve adsorbent having a water capacity of less than 12 percent.
Abstract:
An improved method for the bulk drying of water-containing organic feedstocks by means of selective adsorption of the water in fixed molecular sieve beds wherein the improvement comprises integrating a series of at least four fixed adsorption beds in a manner such that at least two of the beds are always involved in the adsorption-drying phase of the process cycle, and at least two of the beds are always undergoing some portion of the regeneration phase in such a manner that a closed-loop non-condensible purge gas stream used to heat and to cool the beds undergoing regeneration is passed first through the bed being cooled and thereafter through the bed being heated, with the heat energy removed from the former being imparted to the latter.
Abstract:
Cracking catalysts and their use in cracking processes. The cracking catalyst is prepared using novel non-zeolitic molecular sieves and, optionally, traditional zeolitic aluminosilicate cracking components.
Abstract:
Cracking catalysts and their use in cracking processes. The cracking catalyst are prepared using mixtures of catalytic cracking catalysts and selected silicoaluminophosphate molecular sieves.
Abstract:
Silicone compositions, appropriate for dental impressions, curable by a polycondensation reaction catalyzed by a tin II compound. The improvement consists in using tin catalyst stabilized by an amine, which provides the composition with a long useful life (shelf life), before utilization/cure. The compositions advantageously replace the ones from the prior art, polyaddition cured, providing articles with better finishing and uniform surface. The process for preparing the composition and the cure to obtain formed articles are also described.
Abstract:
Synthesis gas comprising carbon monoxide and hydrogen is converted to C5 hydrocarbons suitable for use as liquid motor fuels by contact with a dual catalyst system capable of enhancing the selectivity of said conversion to motor fuel range hydrocarbons and the quality of the resulting motor fuel product. The catalyst composition employs a Fischer-Tropsch catalyst, together with a co-catalyst/support component comprising SAPO silicoaluminophosphate, non-zeolitic molecular sieve catalyst.
Abstract:
The conversion of synthesis gas to liquid molar fuels by means of a cobalt Fischer-Tropsch catalyst composition is enhanced by the addition of molybdenum, tungsten or a combination thereof as an additional component of said composition. The presence of the additive component increases the olefinic content of the hydrocarbon products produced. The catalyst composition can advantageously include a support component, such as a molecular sieve, co-catalyst/support component or a combination of such support components.
Abstract:
Method for slag chemistry control in a refractory lined vessel during the process of refining metal by the injection of oxygen gas during a period of oxidation and by the injection of nonoxidizing gas or gases during a period of reduction and melt specification adjustment such that the slag at the completion of the refining process will have a preselected composition consisting essentially of A% alumina (Al2O3). B% silica (Sio2). C% CaO and D% MgO and a ratio X of alumina to silica equal to a preselected value of between about 0.1 to 10. The preselected slag chemistry at the completion of refining is achieved by using a combination of aluminum and silicon to achieve as completely as possible the preselected ratio of alumina to silica in the slag while at the same time satisfying the fuel, reduction, and specification silicon requirements of the bath at the given intervals corresponding to the end of the oxidizing period, the reducing period and the final trim.
