Abstract
Carbon nanofibers (CNFs) supported nickel catalysts (Ni/CNFs) for hydrogenation of hydrocarbons were prepared by a slurry type impregnation procedure method for the reaction of electrocracking gas in the presence of acetylene and hydrogen in a flow system are investigated. Samples containing 5.0 wt% Ni are capable of complete acetylene conversion over a period of 5 h at 170 °C when using a 27-29% C2H2 and 61-64% H2 from the percentage of composition of electrocracking gas diesel fraction feedstocks. The amount of ethane and ethylene equivalent to approximately half of acetylene converted with propane, propylene and methane formation low, As well as the remaining percentages of acetylene converted into higher hydrocarbons through hydrooligomerization. Predominant product distributions are linear alkenes (C4+ - C5+) followed by branched alkenes (isobutene and isopentene), traces of dienes. Other products, that appear are liquid hydrocarbons or (green oils). Catalytic experiments were performed in a fixed bed reactor at atmospheric pressure, using gas hourly space velocity (GHSV) in 5920 h-1 (30 ml/min) of feedstock gas.
