This 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 800C 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 1000C, multiimpregnated with molten coal tar pitch followed by charring at 750C 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
