  • Process for the production of low ash fuel
    Patent number: 6524354
    Abstract: The present invention describes a process for the production of low ash fuel using calcined petroleum coke by crushing and screening of calcined petroleum coke below 3 mm size, mixing the crushed and screened materials to achieve a bulk density in the range of 760 to 800 kg/m3, mixing 10-100% of the resultant calcined petroleum coke with 0 to 50% coke breeze, pre-soaking the mix so obtained with 5-10% water, mixing with hinder followed by kneading in presence of live stream, then briquetting and curing of the raw briquettes in a furnace in a controlled oxidising atmoshpere to obtain the low ash fuel.
