Analysis of particle and reactor-scale transport-kinetic interactions CO2 methanation

, 2020
The design of an externally cooled fixed-bed reactor for CO2 methanation has been performed using microscopic forms of reaction engineering models that account for both particle-scale and reactor-scale transport-kinetic interactions.

Anti-sintering ZrO2-modified Ni/alpha-Al2O3 catalyst for CO methanation

, 2016
To obviously reduce the sintering behavior of Ni particles in Ni/alpha-Al2O3 catalysts during CO methanation reaction, ZrO2 was deposited onto the Ni/a-Al2O3 catalyst surface by a modified impregnation method.

Complex Iridium Oxides Converge In Structure And Reactivity During Acidic Oxygen Evolution Electrocatalysis

Advanced Energy Materials, EarlyView.
Ir‐based double perovskites restructure during acidic oxygen evolution electrocatalysis through dissolution of non‐Ir cations and convergence toward IrOx active‐site motifs with similar structure and intrinsic activity across compositions. The identity of the dissolving cations controls dissolution and surface reconstruction kinetics, clarifying how ...

Accounting for Substitution: Improving Estimates of GHG Reductions From Cattle‐Based Product Demand Shifts

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT Estimates of reductions in greenhouse gas (GHG) emissions from lower demand for cattle‐based products must account for substitution effects. This study collected data through two surveys—one on ground beef and another on dairy milk—to evaluate substitution effects and potential GHG reductions.

Effect of metal loading and Ce addition on biochar-supported Co catalysts for CO2 methanation

Biochar
CO2 hydrogenation to methane is an interesting topic that can result in CO2 mitigation, providing a solution for global warming. Using a sustainable catalyst in that process will be considered as a plus point that makes the whole system (material ...

Sustainable Productivity Growth in Agriculture: The Role of Shifts in R&D Investments and Technology

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT The objective of the paper is to evaluate the long‐term prospects of sustainable productivity growth linked to plausible assumptions on public agricultural R&D investments as the key productivity driver. Second, it investigates the role of changing R&D focus from yield maximization to input saving technologies (fertilizers and pesticides). The

Climate Change Mitigation in the Dairy Sector: Uncovering Heterogeneity Through Eco‐Efficiency Clubs

Agribusiness, EarlyView.
ABSTRACT Combining climate change goals with economic targets is crucial for the dairy sector, which is a significant contributor to agricultural greenhouse gas (GHG) emissions worldwide. In this paper, we assess economic and climate change implications of dairy production with panel data of Irish dairy farms from 2013 to 2021.

Comparative Life Cycle Assessment and Costing of Biogas Direct Methanation and Water Scrubbing Upgrade

Chemical Engineering Transactions
Biogas CO2 content can be valorized directly through the methanation process without the need for a cleaning step. By integrating biogas production with a methanation system, a net increase in biomethane yield and productivity can be achieved while ...
