Prospective LCA of E‐Methanol Along the Transformation of Steel Industry

Chemie Ingenieur Technik, EarlyView.
The environmental effects of change in steel production route on e‐methanol production are analyzed as they shift from blast furnace route to direct reduction route. Specific hydrogen demand reduces, as do the avoided CO2 emissions. E‐methanol's overall carbon footprint stays in a narrow range of −1 to −1.1 kg‐CO2‐eq./kg‐methanol.

Comparative Assessment of Methanol Production Pathways From Steel Mill Gases

Chemie Ingenieur Technik, EarlyView.
This publication reviews the process concepts and assessments for converting steel mill gases into sustainable methanol, focusing on energy efficiency, and the regulatory framework. From an energy perspective, the production of methanol from BOFG and H2 separated from coke oven gas is of particular interest.

La0.7Sr0.3CuO3−δ: An Interesting Catalyst for Methanol and Ethanol Treatment

, 2013
The reactivity of La0.7Sr0.3CuO3-δ with methanol and ethanol was investigated in oxidation and steam reforming. The conversion is higher in the oxidation reactions (about 100 %) than in steam reforming (78% for methanol, 23% for ethanol).

On Metal Carbonyl Compounds in Catalytic Methanol Synthesis: Detection, Consequences, and Removal

Chemie Ingenieur Technik, EarlyView.
Deactivation of Cu/ZnO/Al2O3 catalysts by metal carbonyl compounds in the feed gas is a critical problem in catalytic methanol synthesis. We utilize PTR–MS to identify potential chemical sources, detect contamination in an in‐house CO gas line, and validate filter methods for removing these catalyst poisons before synthesis.

Techno‐Economic Analysis of Methanol Production From Steel Mill Gases

Chemie Ingenieur Technik, EarlyView.
A techno‐economic analysis for the synthesis of methanol from steel mill gases is carried out. Four different process concepts are defined and analyzed. The analysis yields levelized cost of methanol estimates between €1130 and €1419 t−1. Sensitivity analyses identify hydrogen production as the largest contributor to cost.

Partial oxidation reforming of methanol [PDF]

, 1996
Methanol is an attractive fuel for fuel cell-powered vehicles because it has a fairly high energy density, can be pumped into the tank of a vehicle mush like gasoline, and is relatively easy to reform. For on-board reforming, the reformer must be compact

Developments in the EU Emissions Trading System and Their Effects on CCU Pathways

Chemie Ingenieur Technik, EarlyView.
From an engineer's perspective, the development of the European emissions trading system is analyzed. Difficulties for the use of carbon dioxide, particularly from mixed carbon sources, can be traced back to regulations whose effects might be resolved in the upcoming EU ETS revision. ABSTRACT The analysis presented in this article focuses on provisions

Experimental methods in chemical engineering: Temperature‐programmed desorption—TPD

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Temperature‐programmed desorption (TPD) characterizes the surface active sites of functional materials, such as adsorbents (metal hydrides, porous carbons, zeolites, metal–organic frameworks, for example) and catalysts. Solids surfaces are pre‐treated to remove moisture, contaminants, and previously adsorbed species, then a probe molecule (NH3$
