Governmental subsidies and regulations like the levy of a CO 2 tax
Coke oven gas (COG), a considerable byproduct in coke production, has been utilized as the feedstock for methanol production. A "cradle-to-gate" life cycle assessment (LCA) of COG-based methanol production (COG route) was conducted and compared with the coal and natural gas routes by applying CML 2001 method with GaBi 6.0 software.

A survey was undertaken to assess the state of art of production, …
However, the Life Cycle Assessment (LCA) of hemp-lime concrete shows that the production of lime results in significant GHG emissions (Pretot et al., 2014; Sagastume Gutiérrez et al., 2012; Shan ...
In the next decades, CO 2 capture and utilisation (CCU) technologies can contribute to climate change mitigation. The Columbus project is an example of a CCU initiative in which CO 2 is captured from lime production and converted into E-methane via CO 2 methanation. E-methane can serve as fuel for ships and lorries to replace heavy fuel oil and diesel, respectively.
The Life Cycle Assessment shows that the binders' production dominates the Climate Change, Resources and Ecosystem quality categories while additives are critical in …
The excessive production of bauxite residue (red mud) in the Bayer process is one of the major challenges amongst alumina producers. The Pedersen process is known as a combination of smelting reduction of bauxite and leaching treatment of the produced slag for alumina production, and the process also produces an inert bauxite residue (grey mud), which …
Cement production is an energy-intensive industry that primarily relies on fossil fuels like coal and natural gas to meet energy needs. Extreme usage of fossil fuels leads to depletion of their ...
CaC 2 production is treated as a resource-energy-intensive process. CaC 2 accompanied by electric arc furnace gas (EAFG) as a byproduct is produced industrially by the reaction of lime and coke. This reaction typically occurs in an electric arc furnace (EAF). Electricity is supplied through three electrodes (Hamuyuni et al., 2021) and converted it into heat by the …
The assessment of decarbonization strategies in the lime-based construction materials industry requires a reliable, transparent, robust and flexible life cycle inventory (LCI).
coral mining industry and the alternative options for lime production. For this reason this study was initiated before the enforcement operation was implemented so as to fill in these information gaps. The main objectives of this rapid assessment were; 1 To describe the live coral mining and associated lime production industry in the MBREMP buffer
Biochar has been replaced in lime pastes in different proportions (5, 10, 15, 20, 25 and 30%), and exposed to different curing times (1, 3, 7, 14, 28, 56, 90 and 180 days).
Regardless of whether oxy-fuel or electric heating is used, the generation of high-purity CO 2 increases the partial pressure of CO 2 in the lime kiln reactor and thus impacts the kinetics and overall reactivity of the lime mud during calcination. There is a lack of consensus regarding the impact high partial pressure CO 2 has on the kinetics of lime mud calcination, …
the nal production stages, the Li ₂ CO ₃ production is prominent, with AWARE and WAVE + values of 59.9 m³ and 1.01 m³ equiv. per ton, respectively, largely due to sodium carbonate ...
The thermodynamic analysis of the thermal decomposition reaction of carbonates showed that the temperatures of thermal stability of dolomite and magnesium carbonate are very similar.
(17.68 mmol/L) lime solution prepared with extra pure (Ph. Eur., USP, BP) calcium hydroxide and stored at 40 °C in a laboratory oven for 1 day, 7 days, 28 days and 90 days. At the specified time, the solutions were filtered and titrated with EDTA to …
Reactivity of lime is classified according to the resulting amount of heat: 1. High reactivity lime: The temperature rises 40 C in less than 3 minutes. The reading of thermometer becomes (62 C ). The particle size of lime used in this test is 3.36 mm. 2. Medium reactivity lime: The temperature rises 40 C in 3-6 minutes, and the reaction ends
3.2. Variation in Lime Fixed with Time The variation in the percentage of lime fixed by the various types of fine particle CDW across the 90 days pozzolanic reaction is graphed in Figure 11. The three types of siliceous aggregate wastes exhibited similar behaviour; despite their origin from different recycle plants.
Tung oil lime putty is a unique Chinese traditional organic admixture-lime hybrid paste composed of hydrated lime and boiled tung oil. Thus, polymerized products composed of long chain alkyl and ester molecules with hydrophobic properties are formed, leading to excellent waterproofing [7].Due to this, tung oil lime putty shows certain advantages (e.g., good …
