1. Process for the purification of flue gas, comprising the step of contacting flue gas with a carbonaceous material, comprising a solid carbonaceous residue of synthetic rutile production from production from titaniferous ores.2. Process according to claim 1, further comprising injecting said carbonaceous material into the flue gas to be purified.3. Process according to claim 2, further comprising removing said carbonaceous from the flue gas after sufficient contact time for adsorbing contaminants from the flue gas.4. Process according to claim 3, further comprising:cooling flue gas to a temperature between 0 and 500° C., before contacting it with said solid carbonaceous material; removing dioxins, furans and mercury compounds from the flue gas; contacting said solid carbonaceous material with the flue gas in a dry state, wet state and/or in combination with lime; and sieving, purifying, and/or grinding said carbonaceous material prior to use. 5. The process of claim 4, wherein said flue gas originates from waste incinerators, metallurgical facilities, metal recovery facilities, power plants or cement plants.6. Process according to claim 2, further comprising:cooling the flue gas to a temperature between 0 and 500° C., before contacting it with said solid carbonaceous material; removing dioxins, furans and mercury compounds from the flue gas; contacting said solid carbonaceous material with the flue gas in a dry state, wet state and/or in combination with lime; and sieving, purifying, and/or grinding said carbonaceous material prior to use. 7. The process of claim 6, wherein said flue gas originates from waste incinerators, metallurgical facilities, metal recovery facilities, power plants or cement plants.8. Process according to claim 1, further comprising cooling the flue to a temperature between 0 and 500° C., before contacting it with the said solid carbonaceous material.9. Process according to claim 1, wherein said flue gas originates from waste incinerators, the metallurgical facilities, metal recovery facilities, power plants or cement plants.10. Process according to claim 1, further comprising removing dioxins, furans and mercury compounds from the flue gas.11. Process according to claim 1, further comprising contacting said solid carbonaceous material with the flue gas in dry state, wet state and/or in combination with lime.12. Process according to claim 1, further comprising sieving, purifying, and/or grinding said carbonaceous material prior to use.
