Methanol can be produced from any feedstock that contains carbon such as natural gas, coal, biomass, and CO 2. Methanol production from syngas. About 90% of methanol production is currently from natural gas, and other technologies cannot be substituted on an industrial scale according to undesirable efficiency.

The coaltomethanol (CTM) is an important technical route for methanol process suffers from high CO 2 emission and low energy efficiency due to the mismatch of H/C (hydrogentocarbon) ratio between raw coal and products. Hydrogen production from renewable energy can be introduced into the system to meet the H/C ratio. In this paper, a novel CTM process with nearzero carbon ...
The flow diagram of the CTO process, including the MTO process, is shown in Fig. 2. Coal and water are gasified with the oxygen agent from the ASU, to produce syngas in the CG. The hot syngas is quenched in a radiant cooler and a convection condenser, where heat is recovered to generate steam. ... The energy of coal, methanol, and olefins is ...
Figure 5: A Typical Methanol Oxidative Dehydrogenation Process of Producing Commercial Grade Formaldehyde. Olefins Olefins, such as ethylene and propylene, can be produced from gasification indirectly by catalytic cracking of MeOH, commonly called the methanoltoolefins (MTO) process. Figure 6 shows a simplified flow diagram of UOP's MTO ...
The FischerTropsch process is a catalytic chemical reaction in which carbon monoxide (CO) and hydrogen (H 2) in the syngas are converted into hydrocarbons of various molecular weights according to the following equation: (2n+1) H 2 + n CO → C n H (2n+2) + n H 2 O. Where n is an integer. Thus, for n=1, the reaction represents the formation of ...
In this case study, an entrained flow reactor design shown in Figure 4 and used for the gasification of heavy residue and coal is used, while the process layout is an improved version of Prifti et al.

Process Chemistry. Catalytic conversion of hydrogen (H 2) and carbon monoxide (CO) from coalderived syngas into methanol can be done with conventional gasphase processes, or with a liquid phase methanol (LPMEOH™) process developed by Air Products and Chemicals. The reactions of interest are: 2 H 2 + CO → CH 3 OH. CO 2 + 3 H 2 → CH 3 OH ...
HOW THE STEAM REFORMING REACTION TAKES PLACE The gases required to make Methanol later in the process leaves the Steam Reformer and the mixture is simply called Reformed Gas. The reformed gas contains a lot of unreformed steam at this stage, however this will be cooled, condensed into water and removed.
A coalbased coproduction process of liquefied natural gas (LNG) and methanol (CTLNGM) is developed and key units are simulated in this paper. The goal is to find improvements of the lowearning coal to synthesis natural gas (CTSNG) process using the same raw material but producing a lowmargin, single synthesis natural gas (SNG) product. In the CTLNGM process, there are two innovative aspects.
