520			_aThis work provides a method to use waste carbon was obtained from fly ash of heavy oil incomplete combustion in electric power stations in Egypt to prepare valuable products such as activated carbon, aluminium-dolomite-carbon bricks and Carbon-cuprous oxide composite nanoparticles were chemically deposited on the surface of thin glass tubes of spent energy saving lamps for solar heat collection. Activated carbon (AC) with a surface area of 1050 m2/g was prepared by steam gasification at at {u2264}800{u00B0}C for 90 minutes.Porosity determination showed that it was mainly of mesoporous diameter. The process of activation has xE value of 82.6 kJ/mol. Alumina-dolomite-carbon bricks were made by hot mixing Al2O3, dolomite, C with coal tar pitch. The green bricks were baked at 1000{u00B0}C, multiimpregnated with molten coal tar pitch followed by charring at 750{u00B0}C to seal the porous system of the fired bricks. The prepared brick samples have high density value, good thermal and chemical stability, an outstanding resistance against hydration (> 60 days). Brick body is a heterogeneous composite of dolomite and carbon particles that possess different physico-chemical properties
