What is Preparation and catalytic performance of an efficient Raney nickel catalyst for syngas methanation about?
A new strategy for preparing Raney nickel catalyst was proposed, which could significantly improve the catalytic activity of the catalyst in the methanation of syngas to substitute natural gas in a continuous flow microreactor. The new preparation strategy includes a hydrochloric acid solution quenching process interpolated between two alkali leaching steps. Raney Ni III catalyst showed the best activity with a CO conversion of almost 100% and a CH 4 selectivity of 98% at 548 K under 1.0 MPa with the molar ratio of 3H 2 :1CO and a gas hourly space velocity of 10000 h -1 . The catalysts were characterized by N 2 adsorption-desorption, scanning electron microscopy, X-ray powder diffraction, high-resolution transmission electron microscopy, X-ray photoelectron spectroscopy and temperature-programmed desorption of hydrogen. The results of systematic characterization and catalytic activity evaluation show that the formation of 3Ni(OH) 2 Á2H 2 O in the catalyst is beneficial to the adsorption and activation of hydrogen and the C=O bond, which greatly improves the activity of Raney nickel III in methanation of syngas. Meanwhile, high specific surface area leads to more active sites on the
