摘要:
Synthesis gas is produced by the reaction of light hydrocarbons, primarily methane, in a fluid bed reaction zone of attrition resistant nickel on alpha-alumina catalyst, with steam and oxygen and the conversion level is preserved by limiting the loss of nickel from the reaction and thereby limiting the back reaction of the synthesis gas to form methane in the presence of entrained catalyst in a cooling zone.
摘要:
Light hydrocarbons, e.g., methane are converted to synthesis gas at elevated temperatures and pressures in the presence of a particulate catalyst, e.g., Ni/Al.sub.2 O.sub.3. The conversion of feed to synthesis gas is preserved by rapidly cooling the reaction production to a temperature below that which favors the back reaction of carbon monoxide and hydrogen to form methane.

摘要:
A heavy hydrocarbonaceous oil containing certain types of organic sulfur compounds, such as, dibenzothiophenes, is hydrorefined in two stages with interstage removal of hydrogen sulfide and ammonia. A nickel-containing hydrorefining catalyst is used in the first hydrorefining stage and a cobalt-containing hydrorefining catalyst is used in the second hydrorefining stage.
摘要:
A process for producing transportation fuels, such as gasoline and diesel fuel, from syngas with a low H2/CO ratio. The syngas is first converted to dimethyl ether which is then converted to gasoline by way of a dimethyl ether to gasoline process and to diesel fuel by way of a Fischer-Tropsch process.

Disclosed is a portable demilitarization apparatus and system for segmenting an ordnance and is comprised of a fixed housing having a gantry/robotic positioning system, a high pressure water jet cutting head, and a rotational drive subassembly and a slideable main assembly comprised of a cradle subassembly, a centering ring subassembly, a collection subassembly and a rotational drive mechanism.
摘要:
A method for controlling the peak temperature of a fluid gasification zone used for the gasification of carbonaceous materials to a syngas. Pulsed oxygen is used to control the peak temperature of the gasification zone and to avoid hot spots in the gasifier.
摘要:
Ammonium picrate, Explosive "D", is converted to picric acid, which is then converted to triaminophenol by the conversion of the aromatic nitro groups to amino groups. The triaminophenols are then converted to triaminobenzenes by the removal of the hydroxyl groups and the triaminobenzenes are converted to m-phenylenediamine, aniline, and primary aliphatic amines by the removal of amino groups.

摘要:
A process for the production of chlorates and derivative chemicals from ammonium perchlorate as a starting material. Ammonia is produced in a first step wherein a metal hydroxide is reacted with ammonium perchlorate to produce ammonia and a metal perchlorate. If the metal hydroxide used is sodium hydroxide, sodium perchlorate is formed. The ammonia generated is recovered and sent to a reformer to produce hydrogen which is used to fuel a fuel cell that generates water and electrical energy to run an electrochemical reactor where the metal perchlorate is converted to a metal chlorate and derivative chemicals.
