Carbon Innovation, EarlyView.Synthesis and characterization of sugarcane bagasse‐derived activated carbon via KOH‐assisted dry and wet activation. ABSTRACT This study explores the impact of activation processes on the morphological properties of activated carbon. Carbon is initially produced through vacuum pyrolysis at three temperatures (500°C, 600°C, and 700°C), with a heating ...

Equilibrium Model of Steam Gasification of Coal
Journal of Sustainable Mining, 2013 Coal gasification is a complex process of parallel-consecutive chemical reactions at high temperature between the organic part of coal matter and the gasifying agent. The following two approaches are applied in modelling the coal gasification process: equilibrium and kinetic.

First Operation Results of a Methanol Demonstration Plant With Real Steel Mill Gases
Chemie Ingenieur Technik, EarlyView.A demonstration plant with industrial setup regarding length, diameter, boiling water cooling system and gas recycle was initially operated with cleaned blast furnace gas and compared with earlier experiments with bottle gases. Dynamic disturbances from the steel mill and gas cleaning unit were noticed and could be compensated by the control system ...

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.

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
