Abstract: A process producing electric energy, steam and carbon dioxide in concentrated form from a hydrocarbon feedstock. The process includes forming synthesis gas in an air driven autothermal reactor unit (ATR), heat exchanging the formed synthesis gas and thereby producing steam, treating at least part of the synthesis gas in a CO-shift reactor unit and carbon dioxide separation unit for formation of concentrated carbon dioxide and a lean hydrogen containing gas which is combusted in a combined cycle gas turbine for production of electric energy, and where air from the turbine is supplied to the ATR unit. The exhaust from the gas turbine is heat exchanged for the production of steam which together with steam generated upstream said unit is utilized in a power generator for production of substantially CO2-free electric energy. Steam may be fed to the gas turbine for diluting the hydrogen containing gas mixture.

Abstract: Process for the partial oxidation of a hydrocarbon feedstock, comprising the steps of gasification, partial oxidation and removal of the carbon by forming a soot water slurry containing the unburned carbon and ash and filtration of the soot water slurry to form a filtercake of carbon and ash, wherein the filter cake is dried by means of a fluid bed and the dried filtercake is burned at temperatures between 600.degree. C. and 1000.degree. C. Preferably The fluid bed is operated by means of a fluidizing gas at a temperature of at least 150.degree. C. The dried filtercake is burned under circumstances that carbon is left in the resulting ash.

Abstract: The invention relates to a process for removing heavy metal ash from an aqueous soot suspension like that found in the production of synthetic gas through partial gasification of heavy oils. This soot suspension is treated initially in the standard manner with adjuvants suitable for the separation of soot and which are not miscible in water followed by separation of the aqueous phase. The process is characterized by the fact that ash components in the aqueous phase, are brought to a sedimentation stage for settling and are subsequently removed from the water circulation system.

Abstract: An adsorbent consisting of carbon black pellets, which is formed by aggregation with oil/fats/waxes and other distillation residues of the water containing carbon black separated during the partial gasification/partial combustion of solids and/or liquid combustibles and wherein said aggregation medium is then separated.
