Nowadays, long-chain chlorinated paraffins (LCCPs) enter the environment in large amounts even in non-industrial regions due to their different industrial applications. The standard tests showed that the CPs possess carcinogenic and growth inhibition effects in both terrestrial and marine mammals. In this study, initially, the novel low-cost ZSM-5@Al-MCM nanocatalyst with a Si/Al ratio of 7.80 was prepared by using aluminum foil sheets as the cheap material for the first time and then characterized by FT-IR, SEM, EDX, XRD, and DLS analysis. Afterward, the nanocatalyst was applied for low-temperature destructive hydrodechlorination of long-chain chlorinated paraffins in the presence of NaBH₄ as a safe and easy-to-handle H-donor (instead of gaseous hydrogen) at ambient pressure to produce diesel and gasoline range hydrocarbons as a new approach toward reuse of long-chain chlorinated paraffins instead of their mineralization. The effect of effective factors for instance time, amount of catalyst, and amount of NaBH₄ on the total liquid hydrocarbons (LH) content, diesel/gasoline yield and selectivity were optimized. At optimal experimental conditions, the results showed at a low operating temperature (120 °C), a yield of 74.50%C of LH over C6-C31 with 86.55%C diesel and 8.1% gasoline (4.9%C to C6-C9) selectivity was achieved at reaction time of 3 h. While a moderate temperature (180 °C), 69.5%C LH content over C6-C26 with 34.37% C gasoline and 74.4%C diesel selectivity was achieved within 3 h. The reusability studies showed that the catalyst performance toward destructive hydrodechlorination of LCCPs was stabled for at-least 10 cycles. The possible mechanism for the developed catalytic destructive hydrodechlorination process was also proposed. The developed method can be considered as a novel way for reusing LCCPs instead of common mineralization approaches.
