Abstract: ABSTRACT       Substantially ash-free carbonaceous reductant for use in reduction processes is made by recovering carbon from unused carbon monoxide.  The carbon monoxide contacts a catalyst which promotes formation of carbon on the catalyst. Since the off-gases from many metal ore reduction processes employing coke include a significant quantity of carbon monoxide, this carbon monoxide may be recovered and used to form the reductant which is fed to the reduction process to replace a part of the coke consumed.  Provided most of the carbon monoxide in the off-gases is utilized, very favorable cost savings are achieved when the ash-free reductant is used in place of the coke. Moreover, in some instances, the ore being reduced may be used as the catalyst.  Since this ore-catalyst is at least partially reduced during manu-facture of the reductant, a benefit is obtained.

Abstract: ABSTRACT     Metal substrates in corrosive environments such as gas and oil pipelines, are normally  prone to embrittlement caused by absorption of the hydrogen which is cathodica11y evolved during various corrosion processes.   This is sub-stantially prevented by providing an active substance in the vicinity of the metal substrate, and in electrical contact therewith, the active substance being one on which cathodic hydrogen evolution occurs in preference to the metal, thereby reducing the amount of hydrogen  available for diffusion into the substrate,  The active substrate is preferably a sulphide, for example FeS, or mixed sulphice for example NiCo2S4, and is advantageously applied as a coating on the surface of the substrate, a further coating of, for example, a thermosetting resin, preferably being employed for mechanical and environmental protection.

Abstract: ABSTRACT OF THE DISCLOSURE          Normally solid dissolved coal product and a distillate liquid product are produced by continuously passing a feed slurry comprising raw feed coal and a recycle solvent oil and/or slurry together with hydrogen to a preheating-reaction zone, the hydrogen pressure therein being at least 1500 psig (105 kg/cm2), reacting the slurry therein at a temperature between about 455° and about 500°C to dissolve the coal to form normally liquid coal and normally solid dissolved coal.  A total slurry residence time is maintained in the reaction zone ranging from a finite value from about 0 to about 0.2 hour, and reaction effluent is continuously and directly contacted with a quenching fluid to substantially immediately reduce the temperature thereof below 425°C to substantially inhibit polymerization so that the yield of insoluble organic matter comprises less than 9 weight percent of said feed coal on a moisture-free basis.  The reaction is performed under conditions of temperature, hydrogen pressure and residence time such that the quantity of distillate liquid boiling within the range C5 - 454°C is an amount at least equal to that obtainable by performing the process under the same conditions except for a longer total slurry residence time, e.g., 0.3 hour.  Solvent boiling range liquid is separated and recycled as process solvent.  The amount of solvent boiling range liquid is sufficient to provide at least 80 weight percent of that required for overall solvent balance.  Normally solid deashed coal is produced which possesses a high benzene soluble content which is highly amenable to catalytic hydroconversion to solvent boiling range liquid which can be used to make up any recycle solvent deficiency and to maintain the overall solvent balance of the process.  Likewise, when the short residence time process provides sufficient recycle solvent, distillate liquid can be recovered as an upgraded liquid fuel product of the process.
