(ZA9208919-A)      A hydrogen/halogen electrolytic cell acts as an electric load levelling and load shifting system by storing off peak electricity by electrolysis of conc. hydrohalic acid to form H2, halogen and dil. hydrohalic acid and provides peak electricity by recombining H2 and halogen to form hydrohalic acid for subsequent cycles.    Also claimed is the prodn. of hydrogen halide and O2 by photochemically and thermally reacting H2O and halogen gas and sepg. O2 and halide (I) formed. A method of electrolyte reformation is further claimed where (I) is H2O solvated to form hydrohalic acid.    Also claimed is a photolysis method where a transition metal halide complex is photo excited in soln. in presence of a hydrohalic acid to form molecular halogen. Further claimed is MeOH prodn. where CO2 contg. effluent (II) is contacted with a basic metal oxide bed to convert the bed to the corresp. metal carbonate then decomposing to release CO2 for reaction with H2 in presence of a metal oxide catalyst to form MeOH prod.    USE/ADVANTAGE -   (II) may be from municipal waste combustion thus leading to abatement of greenhouse effect. MeOH prod. is usable as fuel. Contaminated H2O feed stream may be used in electrolyte reformation process.    (ZA9500369-A)      In a hydrogen/halogen electrolytic cell as an efficient battery for electrical load levelling or load shifting, a method is provided for storing off-peak electricity through electrolysing concentrated hydrohalic acid into hydrogen, halogen, and dilute hydrohalic acid. The method also includes providing peaking electricity by recombining the hydrogen and halogen,and producing concentrated hydrohalic acid for subsequent cycles. (To be reissued in later week based on complete specification).    (US5443804-A)      CO2 is removed from water vapour bearing effluent and MeOh is produced simultaneously by reaction of the CO2 with H2 by (A) reacting CO2, obtd. from burning fossil fuel, fermentation, municipal waste treatment or lime kiln operation, by flowing contact of the effluent with a bed of basic metal oxide, pref. MgO, ZnO and/or CdO, at a suitable press and temp to form a metal carbonate, (B) terminating the contact when the bed has been virtually converted to carbonate, (C) heating the carbonate to a temp and press suitable to release CO2 and (D) mixing the released CO2 with H2 and passing the mixt at a suitable temp and press over another metal oxide, pref ZnO on ZrO2, CuO on ZnO and/or CuO/ZnO/Al2O3, to form MeOH.    Step (A) is pref conducted at 330-380 deg.C under atmos pressure step (C) at 475-550 deg.C under atmos pressure and step (D) at 140-310 deg.C under 4-55 atm pressure. The H2 is obtd. from radiation augmented hydrolysis. Hydrocarbons are also produced in step D).    USE/ADVANTAGE -   To reduce emission of green house gases and to produce MeOH. Better equipment is used by a better method than known ones utilising solar energy. The method can be operated (dis)continuously. Potable water can be obtd from contaminated water.
