“…The same consideration is for the recycle of produced stream, factor D: it has a positive effect on the methanol production (by increasing recycling, the methanol production increases), but the effect is negative in interaction with factor C. In fact, methanol reaction is limited by chemical equilibrium, and the recycling flow can prevent related problems-particularly at high temperature, increasing the methanol production [63]. Obviously, recycling the stream increases the amount of total feed, and consequently CO and CO 2 conversion is decreased due to decreased residence time.…”

Carbon dioxide conversion and utilization is gaining significant attention worldwide, not only because carbon dioxide has an impact on global climate change, but also because it provides a source for potential fuels and chemicals. Methanol is an important fuel that can be obtained by the hydrogenation of carbon dioxide. In this research, the modeling of a reactor to produce methanol using carbon dioxide and hydrogen is carried out by way of an ANOVA and a central composite design. Reaction temperature, reaction pressure, H 2 /CO 2 ratio, and recycling are the chosen factors, while the methanol production and the reactor volume are the studied responses. Results show that the interaction AC is common between the two responses and allows improvement of the productivity in reducing the volume. A mathematical model for methanol production and reactor volume is obtained with significant factors. A central composite design is used to optimize the process. Results show that a higher productivity is obtained with temperature, CO 2 /H 2 ratio, and recycle factors at higher, lower, and higher levels, respectively. The methanol production is equal to 33,540 kg/h, while the reactor volume is 6 m 3 . Future research should investigate the economic analysis of the process in order to improve productivity with lower costs.

“…At a 5 % CO 2 recycle ratio, the methanol production increased by about 2.5 % compared to an operational methanol process. The methanol synthesis process was modeled in [6] in order to maximize the CO 2 conversion as well as the production rate of methanol. The CO 2 utilization potential for methanol synthesis was investigated by Raudaskoski et al [7].…”

Methanol production through CO2 hydrogenation was investigated in a series of fixed‐bed reactors. Staging of the reactor into several smaller reactors is considered to enhance methanol production, in addition to maximizing a measure of annual profit. The degrees of freedom of the reactor system are the number of stages, the cooling medium temperature, the heat transfer area, and the volume of the stages. Depending on the objective function (OF) criteria, staging of the reactor increases the OF values to various extents. When the objective is to maximize the methanol production, the OF of a three‐stage reactor system with an inlet H2/CO2 ratio of 2 is 2.61 % higher than in the single‐stage configuration. Staging of the reactor also increases the synthesis gas conversion to methanol. However, if maximizing the annual profit is the objective, the profitability of the two‐stage configuration is 2.05 % greater than in the case with one reactor, due to the higher methanol production of the staged reaction system.

“…Methanol production and demands have shown a substantial increasing trend in the coming years. It is regarded as an excellent alternative energy resource due to its excellent combustion properties [16][17][18][19][20]. Methanol is also a very important primary raw material for production of various chemicals such as acetic acid, dimethyl ether (DME), methyl tert-butyl ether (MTBE) and formaldehyde [21][22][23][24].…”

Development of an Efficient Methanol Production Process for Direct CO2 Hydrogenation over a Cu/ZnO/Al2O3 Catalyst

Carbon capture and utilization as a raw material for methanol production are options for addressing energy problems and global warming. However, the commercial methanol synthesis catalyst offers a poor efficiency in CO 2 feedstock because of a low conversion of CO 2 and its deactivation resulting from high water production during the process. To overcome these barriers, an efficient process consisting of three stage heat exchanger reactors was proposed for CO 2 hydrogenation. The catalyst volume in the conventional methanol reactor (CR) is divided into three sections to load reactors. The product stream of each reactor is conveyed to a flash drum to remove methanol and water from the unreacted gases (H 2 , CO and CO 2 ). Then, the gaseous stream enters the top of the next reactor as the inlet feed. This novel configuration increases CO 2 conversion almost twice compared to one stage reactor. Also to reduce water production, a water permselective membrane was assisted in each reactor to remove water from the reaction side. The proposed process was compared with one stage reactor and CR from coal and natural gas. Methanol is produced 288, 305, 586 and 569 ton/day in CR, one-stage, three-stage and three-stage membrane reactors (MR), respectively. Although methanol production rate in three-stage MR is a bit lower than three stage reactors, the produced water, as the cause of catalyst poisoning, is notably reduced in this configuration. Results show that the proposed process is a strongly feasible way to produce methanol that can competitive with a traditional synthesis process.
