Storage of Naphtha for a long time can cause some degradation , if some Cracked naphtha is stored with the Straight run and Hydrotreated naphtha , also it depends type of Cracked Naphtha stream . Cracked Naphtha is prone to degradation. Due to autoxidation reactions there is colour formation and instability of the fuel, due to some colour precursor species present in the fuel.
