When liquid hydrocarbons are decomposed in an electrical discharge, as well as gas containing up to 30 vol.% of acetylene, we also obtain condensation products (soot) which we find in a dispersed state in the processed products. It has been shown [1–3] that the yield of soot depends largely on the nature of the initial raw material, and increases as we go from volatile to high-boiling petroleum products. It has been found experimentally [4] that the presence of small quantities of condensation products (15–20 g/liter) in the circulating liquid feedstock, when high-voltage discharges are being used, promotes the decomposition process by facilitating electrical breakdown; but larger concentrations (greater than 50 g/liter) cause short-circuiting of the electrodes by soot “bridges.” In a continuous process it is therefore necessary to remove part of the liquid product, together with the soot, from the cycle. |
