| Abstract: | The catalytic pyrolysis of C1–C4 light hydrocarbons in a continuous tubular reactor in the presence of ultrafine metal particles formed by electrical exploding of monometallic (Ag, Al, Cu, Fe, Ni, Ti, Pt, W, Mo) and bimetallic (Mo, Cu; Fe, Al; W, Ni; W, Pt) wires has been studied. The study has been performed in the temperature range of 500–850°C, a gas mixture flow rate of 50–100 mL/min, and a contact time of 5–10 s. The catalytic activities of ultrafine particles have been matched under comparable conditions, the influence of the metal nature on the yield of ethylene and propylene has been examined, and sooting has been evaluated. The best results for the basic parameters of the catalytic pyrolysis of C1–C4 hydrocarbons (yield of ethylene and propylene, ethylene selectivity, and coking) have been shown by W, Fe, and Mo ultrafine particles obtained by electrical explosion of respective wires. |
