Conversion of Liquefied Hydrocarbon Gases on Industrial Nickel Catalysts


The two-stage conversion of industrial liquefied hydrocarbon gases (LHGs) on NIAP-07-01 (NKM-1) and NIAP-03-01 catalysts is studied to obtain hydrogen-containing gases. The experiments are performed in flow reactors with fixed catalyst layers at a pressure of 0.1 MPa under the conditions of pre-reforming: temperature, 350–450°С; GHSV = 1000–3000 h−1; steam : gas ratio, (4 : 1)–(8 : 1). For steam–air reforming: temperature, 700°С; GHSV = 2000 h–1; air : gas ratio, 1.2 : 1. The concentrations of converted gas components under these conditions correspond to equilibrium values calculated using the Peng–Robinson model. The conversion of methane homologs is almost 100% during the pre-reforming stage, while the concentrations of methane and hydrogen are 32–54 and 24–47%, respectively. The main condition for the pre-reforming of hydrocarbon gases with a high methane equivalent is a Н2О : С ratio greater than 2 to avoid the formation of elemental carbon (carbonization). The yield of hydrogen-containing gas during two-stage reforming is 15.6 m3, obtained from 1 m3 of initial LHGs with a hydrogen content of 41.81%, and the total amount of CO and H2 is more than 52%.
