The methanol-to-gasoline (MTG) and methanol-to-olefins (MTO) process are 2 epochal technological discoveries in the synfuels arena, first introduced by Mobil Oil Corporation, some 50 years after the Fischer-Tropsch process. Apart from the technological breakthroughs, the MTG and MTO processes have also provided a rich tableau for scientific research and pursuits. In this report, we will first provide anecdotal information pertaining to the discovery and development of these 2 processes. We will then focus on how the MTO process has evolved into a stand-alone technology in its own right for the 2 value-added products, ethylene, and propylene.

“…Details for the kinetics and reaction conditions for the methanol/DME conversion into olefins are presented elsewhere . In general, catalysts (zeolites) for the production of olefins are characterized by smaller pore sizes compared to the production of gasoline . Lower partial pressures of DME and higher reaction temperatures lead to a shift in the product distribution to lighter hydrocarbons .…”

“…A description of such a process is given by Avidan and was developed by Mobil . Despite the greater complexity of this route, the gasoline fraction is usually better quality, as the durene content is lower compared to gasoline produced via the MTG route . However, there is a lack of public information on specific reaction conditions and process configuration.…”

This critical review focuses on potential routes for the multi-production of chemicals and fuels in the framework of thermochemical biorefineries. The up-to-date research and development in this field has been limited to BTL/G (biomass-to-liquids/gases) studies, where biomass-derived synthesis gas (syngas) is converted into a single product with/without the co-production of electricity and heat. Simultaneously, the interest on biorefineries is growing but mostly refers to the biochemical processing of biomass. However, thermochemical biorefineries (multi-product plants using thermo-chemical processing of biomass) are still the subject of few studies. This scarcity of studies could be attributed to the limitations of current designs of BTL/G for multi-production and the limited number of considered routes for syngas conversion. The use of a platform chemical (an intermediate) brings new opportunities to the design of process concepts, since unlike BTL/G processes they are not restricted to the conversion of syngas in a single-reaction system.Most of the routes presented here are based on old-fashioned and new routes for the processing of coaland natural-gas-derived syngas, but they have been re-thought for the use of biomass and the multiproduction plants (thermochemical biorefinery). The considered platform chemicals are methanol, DME, and ethanol, which are the common products from syngas in BTL/G studies. Important keys are given for the integration of reviewed routes into the design of thermochemical biorefineries, in particular for the selection of the mix of co-products, as well as for the sustainability (co-feeding, CO2 capture, and negative emissions).

“…The methanol to hydrocarbons (MTH) reaction represents an industrially applied alternative to crude oil based processes, enabling the production of light olefins (MTO), gasoline (MTG) or aromatics (MTA), from abundant and economically viable feedstocks (e.g. natural gas, biomass or coal) [1][2][3]. The sustainable advantages of these processes are however hampered by the relatively fast deactivation of the zeolite catalysts on which the process relies [4].…”

Operando UV-Raman study of the methanol to olefins reaction over SAPO-34: Spatiotemporal evolution monitored by different reactor approaches

et al. 2019

A molecular understanding of coke formation during the methanol to olefins (MTO) reaction is of great importance in order to adopt strategies that can improve the lifetime of the catalyst. UV-Raman has proven to be a valuable characterization tool, because of the favorable resonance conditions achieved towards key coke components, e.g. aromatic and olefinic compounds. Still, the applicability of UV-Raman in MTO is limited by the high risk of inducing sample damage under the exposure to the intense UV excitation laser. This drawback has been addressed by specific experimental setups, exploiting the concept of sample movement under the laser beam during the measurement, so that the laser-sample interaction is minimized by averaging over a wider sample surface. In this work, the impact of two different experimental setups, both relying on sample movement, are evaluated for the operando investigation of the MTO reaction over a SAPO-34. While in one case the whole catalytic bed is moved (fluidized bed), in the other case the sample is pressed into a pellet and rotated. Due to the peculiar spatial evolution of the reaction zone during MTO in a fixed-bed reactor, each method provides valuable information, but at very different spatiotemporal scales.
