Synthesis of Carbon Nanofibers from Decomposition of Liquid Organic Waste from Chemical and Petrochemical Industries

摘要: Abstract This work investigates the possibility of using electrocracking for decomposition liquid organic waste from chemical and petrochemical industries. approach yields a gas containing 22-23% acetylene wide range valuable products lower olefins, paraffin, hydrogen. The concentration reported herein is unattainable by other processes production hydrocarbon feedstock, this method more environmentally friendly than carbide method. Electrocracking very promising raw material synthesis carbon nanostructures nanofibers (CNFs) in particular, its use these purposes creates viable preconditions establishment an integrated technology utilization waste. electric discharge process has marked advantage that power consumption low (8-10 kW.hr per 1 m3 C2H2). growth Ni-Al2O3-catalysed at temperatures 250–550 °C space velocities 1500-3000 h-1 been investigated fixed bed reactor. Scanning electron microscopy (SEM), X-ray powder diffraction (XRPD), Raman spectroscopy were used to characterize nanofibers. We demonstrate with diameters mostly between 21.3 60.6 nm can be synthesized uniformly densely on catalyst.
