Abstract
Researchers investigated 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.
They conducted the study 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 were matched under comparable conditions, the influence of the metal nature on the yield of ethylene and propylene were examined, and sooting was evaluated. The best results for the basic parameters of the catalytic pyrolysis of C₁–C₄ hydrocarbons were observed to be W, Fe, and Mo ultrafine particles obtained by electrical explosion of respective wires.
