Hydrocarbyl polyoxyalkylene aminoalcohol and fuel composition containing same

An ash fusion temperature increasing agent principally comprising a silicon and/or titanium compound, such as SiO.sub.2 and/or TiO.sub.2 is mixed with an ash-containing fuel comprising a pumpable liquid hydrocarbonaceous material and/or petroleum coke to produce Mixture A. In one embodiment, the ash fusion temperature increasing agent comprises about 55-100 wt. % of silicon compound selected from the group consisting of fine silica or quartz, volcanic ash, and mixtures thereof; and the remainder, if any, of said ash fusion temperature increasing agent comprises a member of the group consisting of aluminum compound such as Al.sub.2 O.sub.3, magnesium compound such as MgO, and mixtures thereof. Mixture A is reacted with a free-oxygen containing gas in a free-flow refractory lined reaction zone of a partial oxidation gas generator. A hot raw effluent gas stream comprising H.sub.2 +CO along with fly-ash having an increased initial deformation temperature are produced at a higher temperature. Alternatively, Mixture A may be first introduced into a coking zone and converted into petroleum coke in which the ash fusion temperature increasing agent is dispersed throughout. The petroleum coke entrained in a liquid or gaseous carrier is then introduced into the partial oxidation gas generator where a hot raw effluent gas stream comprising H.sub.2 +CO is produced along with fly-ash having an increased ash fusion temperature. The fly-ash is readily separated from the effluent gas stream; and, the gas generator may be operated in the fly-ash mode at a higher temperature, thereby yielding higher carbon conversions while extending the life of the refractory lined reaction zone.

Partial oxidation process

An ash fusion temperature reducing agent comprising a comminuted ore mixture of the silicates of iron, calcium, magnesium and aluminum is mixed with an ash containing pumpable liquid hydrocarbonaceous material to produce Mixture A. Mixture A is reacted with a free-oxygen containing gas in a partial oxidation gas generator. A hot raw effluent gas stream comprising H.sub.2 +CO along with molten ash having a reduced ash fusion temperature are produced at a lower temperature. Alternatively, Mixture A may be first introduced into a coking zone and converted into petroleum coke in which the ash fusion temperature reducing agent is dispersed throughout. The petroleum coke is then introduced into the partial oxidation gas generator where the hot raw effluent gas stream comprising H.sub.2 +CO is produced along with molten petroleum coke ash having a reduced ash fusion temperature. The molten ash is readily separated from the effluent gas stream and the gas generator may be operated at a lower temperature thereby extending the life of the refractory lined reaction zone.

A method of producing a thick slurry of powdered coal and water. It includes feeding less coal than is required for the thick slurry into a ball mill, and introducing all of the water required so that a thin slurry is produced. The remaining coal required is pulverized in a dry grinder, and the thin slurry and dry powdered coal are mixed to produce the desired thick slurry.

Method of producing a coal-water slurry of predetermined consistency

An extruder for feeding finely divided solids. And, in combination therewith, means for using gas in various ways to repulverize the finely divided solids. It lends itself to a procedure for continuously charging finely divided solids with water into a high pressure reactor. The high pressure is inherently contained, and the solids are repulverized for use in a reaction.

Method of charging solids into coal gasification reactor

A method of feeding powdered coal to a high pressure reactor which is being used with a fluidized bed/entrained flow coal gasification process. It includes steps of feeding a moist powdered coal to an extruder, and extruding the mixture into a high pressure stream of gas. The extrudate is dispersed into the gas stream, and the stream of extrudate and gas carrier is dried. Then the dry extrudate is separated and fed into the reactor vessel.
