An Investigation into the Effect of Hydrotalcite Calcination Temperature on the Catalytic Performance of Mesoporous Ni-MgO-Al2O3 Catalyst in the Combined Steam and Dry Reforming of Methane

Gholamreza Roohollahi; Mohammadreza Ehsani

Volume 8, Issue 4 , October 2019, , Pages 64-84

  Several mesoporous nickel-based catalysts with MgO-Al2O3 as the catalyst support were prepared using a co-precipitation method at a constant pH. The supports were prepared from the decomposition of an Mg-Al hydrotalcite-like structure which had already been prepared with Mg/Al=1. Prior to impregnating ...  Read More

Prediction of the Products Yield of Delayed Coking for Iranian Vacuum Residues

Farshad Torabi Esfahani; Javad Ivakpour; Mohammadreza Ehsani

Volume 7, Issue 3 , July 2018, , Pages 53-64

  In this work, new correlations are proposed to predict the products yield of delayed coking as a function of CCR and temperature based on the experimental results. For this purpose, selected Iranian vacuum residues with Conradson carbon residue (CCR) values between 13.40-22.19 wt.% were heated at a 10 ...  Read More

An Experimental Study of Adsorption Breakthrough Curves for CO2/CH4 Separation in a Fixed Bed of Nanoporous Shaped Copper Trimesate Metal Organic Framework

Tahereh Asadi; Mohammadreza Ehsani

Volume 2, Issue 4 , October 2013, , Pages 54-66

  Copper trimesate (Cu-BTC) MOF has been pointed out as a promising adsorbent for separating carbon dioxide from methane. However, MOF’s need to be shaped prior to their use in packed bed adsorbers in order to reduce pressure drop; on the other hand, the production of mechanically resistant shaped ...  Read More
