Abstract: The Mannich reaction products of certain diaminopropanes with formaldehyde and salicylic acids are potent carburetor detergents and corrosion inhibitors in hydrocarbon fuels, particularly in gasoline.

Abstract: A slag trap structure is for use where synthesis gas is generated having small particulate slag entrained therewith. It has a high pressure shell with a body of water at the bottom for quenching and removing the slag. There is a coaxial inner wall to direct the flow of synthesis gas and slag down from an inlet at the top toward the body of water. And there is an outlet spaced substantially above the level of the water to cause reversal of the gas and slag flow. Also, there is means for recirculating some clean gas in conjunction with the inner wall to direct a swirling flow that confines the downward flow centrally in the vessel.

Abstract: The spreadability of marine diesel cylinder oils is improved by the incorporation therein of a spreadability improving amount of a polyalkoxylated phenoxy compound having the formula: ##STR1## wherein R is an aliphatic hydrocarbyl group having from 5 to 70 carbon atoms and n ranges from 14 to 30.

Abstract: Bitumen is recovered from a subterranean formation of heavy oil sands traversed by at least one injection well and at least one associated production well in fluid communication with each injection well. Air in admixture with a heating fluid selected from the group consisting of low quality steam, hot water, or mixtures thereof, and an alkalinity agent are injected into the formation by way of each injection well. The subterranean heavy oil sands are thereby raised to a temperature in the range of about 200.degree. to 350.degree. F. A portion of the bitumen at reduced viscosity is oxidized without burning to produce additional petroleum acids which are neutralized to form emulsifying agents. The condensed steam and/or hot water contacting the bitumen form with it a bitumen-water emulsion. By pressure from the injected mixture of air and heating fluid, the resulting bitumen-water emulsion is then recovered from each production well.

Abstract: Hot synthesis gas is cooled and deashed by passage through first zone in contact with a downwardly descending film of cooling liquid, a second zone in contact with a spray of cooling liquid, a third zone in contact with a body of cooling liquid, and a fourth zone in contact with a spray of cooling liquid--at least a portion of the cooling liquid to the first zone preferably being recycled cooling liquid from which at least a portion of the solids contained therein has been removed.

Abstract: Method and/or system for removing liquid slag from a pressurized gasifier. Hot liquid slag is quenched in a quenching medium such as water. The quenched and solidified slag is crushed to a maximum particle size. The crushed slag and quenching medium are alternatively connected to opposite ends of a floating piston while the other end is connected to an outlet for disposal of the slag. The crushed slag and quenching medium are subjected to the gasifier pressure so that the piston acts to forceably eject the mixture through the outlet.

Abstract: An improved method for preparing sulfurized triisobutylene whereby the sulfurization reaction is conducted in the presence of a N-halogen substituted organic promotor selected from the group consisting of N-halo aniline, N-halo succinimide and 1,3-N-dihalo dialkylhydantoin is provided.

Abstract: A continuous process for preventing the build-up of metals from the hydrocarbonaceous fuel feed in a partial oxidation system in which about 80-100 wt. % of the carbon-soot produced is recycled to the gas generator. By the subject process a significantly large portion of the metals and metal compounds i.e. ash in the soot-water feed stream to the decanter become concentrated in the grey water that separates out in the decanter in the carbon recovery section. The concentration of ash suspended in the grey water may be then easily reduced in a solids-liquid separator with or without the addition of a flocculant and prior to recycling a portion of the grey water to the gas quench tank and/or gas scrubber.

Abstract: A novel fuel composition contains gasohol plus, as a wear-inhibiting additive, a reaction product of an acrylic acid or methacrylic acid and an amine such as mono-oleyl amine.

Abstract: Outlet structure of a powdered coal gasification generator. The bottom of the generator has an outlet throat with cylindrical walls that extend beyond the base. And, the walls terminate in an oblique manner with a face shaped to promote flow of slag from the generator to a single point in order to minimize reentrainment of slag into the gasification products.

Abstract: Disclosed are beta-amino acid derivatives which impart friction reducing properties to lubricating compositions. The additives of the invention are bifunctional carboxylic acid salts and amides derived from the basic hydrolysis of a cyanoethylated amine.

Abstract: Burner for use in a coal gasification process wherein a combustible mixture is formed comprising a combustion supporting gas such as oxygen, and a coal slurry. To avoid deposition of slag and ash particles along the hot, exposed face of the burner, a dynamic fluid blanket or barrier is directed transversely of the burner face. The fluid flow originates at the burner periphery and is addressed to sweep, or impinge against at least a part of the burner face adjacent to the central opening which defines the burner discharge port.

Abstract: In the combination of a reactor vessel which includes a quench ring and a dip tube surrounding a bottom outlet, there is an improved quench ring structure. It includes a first annular cooling conduit mounted against the floor of the reactor chamber and surrounding the outlet. That floor supports a refractory lining. There is a second annular cooling conduit mounted beneath the first conduit. And, there is a high temperature resistant seal between the two conduits. The result maintains a tight seal against escape of high temperature reactor gas, in spite of any warping of the reactor floor.

Abstract: A fuel composition comprising a mixture of hydrocarbons boiling in the middle distillate boiling range and an effective stabilizing amount of a alpha, omega diamino poly(oxypropylene) poly(oxyethylene) poly(oxypropylene) represented by the formula: ##STR1## wherein x and z each has an approximate value ranging from 1 to 3 such that the sum of x plus z has an average value ranging from 3 to 4, and y has an approximate value ranging from 10 to 16.

Abstract: A high turndown de-slagging burner is provided for simultaneously introducing one or two mixed pairs of reactant feedstreams into a free-flow noncatalytic partial oxidation gas generator for the production of synthesis gas, fuel gas, or reducing gas by way of the central and/or annular sections of the burner, respectively. Each pair of feedstreams comprises a stream of free-oxygen containing gas with or without a temperature moderator and a pumpable liquid slurry stream of solid carbonaceous fuel, such as a coal-water slurry. Other hydrocarbonaceous fuels may be employed. The burner comprises four coaxial concentric conduits that are radially spaced to provide coaxial concentric annular passages. All of the conduits and annular passages are closed at the upstream ends and open at the downstream ends. Each pair of feedstreams is separately mixed together in a central or annular pre-mix chamber located upstream from the face of the burner.

Abstract: The ability of marine diesel engine cylinder lubricants is improved by the incorporation therein of a spreadability improving amount of at least one polyoxyethylene ester of the formula: ##STR1## wherein n ranges from 18 to 22 and R is an alkyl group having 11 to 17 carbon atoms in the chain.

Abstract: Toxic inorganic CN-containing sludge as produced by treating at least a portion of the water used to quench cool and/or scrub the hot raw effluent gas stream from a partial oxidation gasifier with a ferrous salt and a base may be disposed of by separating the inorganic CN-containing sludge from the water and introducing the sludge into the partial oxidation gas generator in admixture with the hydrocarbonaceous fuel feed. Most of the cyanides are effectively destroyed in the reaction zone, and the ash components in the waste solids are recovered as slag from the generator. The separated water is upgraded by further treatment and recycled to the quench tank and/or gas scrubber. The subject process provides an environmentally safe solution for the otherwise costly problem of disposing of toxic sludge. When coal is included in the feed to the gas generator, any calcium in the sludge will act as a fluxing agent for the coal ash. A more fluid slag having a lower ash-fusion temperature is obtained.
