Abstract
The unique properties of carbon nanofibers (CNFs), a novel structured carbon material developed in the last two decades, have generated a large number of applications including selective absorption, energy storage, polymer reinforcement, and catalyst supports. The results show the possibility production of olefin hydrocarbons from gas electrocracking as a first stage, and the subsequent stage investigated the regularities of the oligomerization of acetylene in the gas electrocracking on palladium catalyst, we supported palladium on CNFs and developed a highly active catalyst for hydrogenation of hydrocarbons. CNFs supported palladium catalysts (0.5%Pd) were prepared by a standard incipient impregnation method using aqueous solutions of palladium (ΙΙ) chloride PdCl2 as a palladium precursor. Carbon nanofibers (CNFs) were synthesized from a previous studyto us, obtainedalsofrom acetylene in the gas electrocracking over γ-Fe2O3 catalyst, oligomerization of acetylene with a Pd/CNFs catalyst has been investigated. Catalytic experiments were performed in a fixed bed reactor at atmospheric pressure, synthesized at(140 – 270) ºC, using gas hourly space velocity (GHSV) in the range (3000-7000) h-1 of feed gas. Resulting shows that the yield of green oil or (liquid hydrocarbons) reduce when the temperature increase and increase in the yield of methane, ethene, propene and butene, as well as a more stable catalyst.
