Random forest regression for catalyst performance prediction and validation of tri‐reforming of methane (TRM)

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Carbon dioxide‐reduced hydrogen can be synthesized through various methods such as dry‐reforming (DRM), steam reforming (SMR), and partial oxidation (POX). Tri‐reforming of methane (TRM) is a promising technology which combines all the above‐mentioned processes for the simultaneous production of hydrogen and syngas with high energy efficiency.

WSPLK: A systematic approach to the thermodynamic characterization of light and heavy Mexican crude oil

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract A streamlined characterization framework (WSPLK) is presented for modelling complex reservoir fluids using cubic equations of state. The key methodological contribution is the introduction of a single global parameter ε directly into Pedersen's boiling‐point correlation, restoring pure‐component calibration and eliminating the need for ...

CO2 Methanation: Principles and Challenges

, 2019
The power to gas (P2G) process has the potential to solve long-term and large-scale energy storage problems as well as reduce CO2 emissions. P2G involves CO2 methanation as a pillar of the process for the production of synthetic natural gas. Therefore, this chapter focuses on the principles and fundamental challenges of the CO2 methanation.

CO2 methanation and co-methanation of CO and CO2 over Mn-promoted Ni/Al2O3 catalysts

Frontiers of Chemical Science and Engineering, 2016
A series of Mn-promoted 15 wt-% Ni/Al2O3 catalysts were prepared by an incipient wetness impregnation method. The effect of the Mn content on the activity of the Ni/Al2O3 catalysts for CO2 methanation and the comethanation of CO and CO2 in a fixed-bed reactor was investigated.

Bimetallic Zeolite Catalyst for CO2 Reforming of Methane

Topics in Catalysis, 2009
The catalytic activity of Ni–Rh on the synthesized BEA zeolite in carbon dioxide reforming of methane has been investigated. Catalysts were prepared using the incipient wetness impregnation method, with a total content of metals up to 5 wt%. Catalysts were characterized through XRD, TPR, N2 adsorption, SEM, AAS, TG/DSC analyses.

Catalytic methanation of CO2 with NH3

Catalysis Today, 2017
Abstract The catalytic methanation of CO2 with ammonia over Ni, Pt, and Ru catalysts impregnated on γ-alumina was carried out in a fixed-bed reactor under atmospheric pressure at 573–873 K. The methanation of CO2 with NH3 is considered to occur in two stages –NH3 decomposition into H2/N2 followed by CO2 methanation with H2. 1 wt% Pt/γ-Al2O3 exhibited

Upgrading CO2 with methane

Science, 2016
Catalysis The use of carbon dioxide as a reactant could help to mitigate its impact on climate, but it is difficult to activate as an oxidant. Buelens et al. combined methane in a high-temperature “super-dry” reforming process that generates reactive carbon monoxide. Both molecules were fed into a reactor containing a nickel methane-reforming catalyst,

RhNi nanocatalysts for the CO2 and CO2+ H2O reforming of methane

Catalysis Today, 2011
Abstract Monometallic and bimetallic RhNi nanocatalysts, supported on a nanofibrous alumina, employed for H2(+CO) production by CO2 and CO2 + H2O reforming of methane were prepared and tested under reaction conditions. The catalysts were characterized before and after reaction by conventional methods.
