Comparative analysis of life cycle water accounting of the Lurgi low-pressure methanol production process with biomass or coal as raw materials

Preliminary study of the methanol production process from coal to support the coal downstream program

“…As of 2011, most of the methanol plants used licenses from Lurgi (27%), JM / Davy (25%), Topsøe (16%) followed by MGC, JM / Uhde, JM / Jacobs, JM / Others, JM / Toyo [9]. All technologies use the concept of technology integration from the starting of the gasification process, gas cleaning to synthesis.…”

“…All technologies use the concept of technology integration from the starting of the gasification process, gas cleaning to synthesis. Thus, energy efficiency and high carbon conversion are 67% and 83%, respectively [9].…”

“…This Sasol-Lurgi fixed bed gasification technology has been applied commercially. The Sasol-Lurgi gasifier is known as a fixed bed dry bottom (FBDB) gasifier where the ash produced is solid [9]. In fixed bed gasification technology, coal grains are stacked on top of a grid (grate) and reagents (air/oxygen/water vapor) are passed into the pile.…”

Photo‐Induced C1 Substitution Using Methanol as a C1 Source

“…Methanol, the simplest aliphatic alcohol, are produced over hundreds of million-tons-scale every year from syngas, natural gas, coal, biomass, the distillation of wood, and also photo/ electrocatalytic CO 2 reduction. [8][9][10][11][12][13] Under the background of carbon neutrality, the industrial synthesis technology of methanol with catalytic reduction of carbon dioxide as raw material has been developed rapidly, realizing the low cost of methanol production. Owing to its low cost, low toxicity, and easy activation, methanol has been considered to be a sustainable C/H/O carrier and platform chemical that widely used as fuel, solvent, the cheapest hydrogen energy storage molecule, the feedstock for manufacture of bulk chemicals such as formaldehyde, acetic acid, methyl esters, methylamines, dimethyl ether, and lower olefins.…”

Case analysis and future aspects of photo/thermocatalytic hydrogen production from methanol

“…Several processes have been presented until today to obtain hydrogen from methanol such as pyrolysis, thermocatalytic reforming, fermentation, etc. 5 However, the yield of hydrogen in these methods is not genuinely satisfactory. After long term studies over the years about hydrogen production, researchers examined the decomposition 6 and steam reforming of methanol 7 as new green processes 8 to produce hydrogen.…”
