“…The maximum IRR corresponds to the ATR-03 (28.74%), being significantly larger than the conventional value usually assigned in similar BTL/G studies (IRR = 10%) [1,[15][16][17][18] when computing the minimum selling price of products.…”

“…In this work, data from various recent developments have been considered: (i) for the hydrocarbonylation cases a combination of a carbonylation (H-Mordenite) and a hydrogenation (Cu-ZnO) catalyst is used. The performance of these catalysts has been successfully tested in a dual fixed bed reactor fed with syngas and DME [2][3][4], whereas the technical considerations are taken from [1];…”

“…For the design of the DME hydrocarbonylation section, a CO/DME ratio of 10 was used on the basis of recent results [1]. Collected liquid products from the reactors (methanol, ethanol and small amounts of methyl acetate) are mixed and sent to the product separation section.…”

“…The H 2 /CO ratio is adjusted by setting the steam to hydrocarbon ratio, ensuring no carbon deposition over the catalyst. The reformed syngas is cooled, compressed and dehydrated in a molecular sieve, preventing the presence of water in either the DME hydrocarbonylation or in the DME carbonylation reaction section [1].…”

“…However, studies on the co-production of biochemicals and biofuels via indirect synthesis routes are scarce. Ethanol production from lignocellulosic biomass via dimethyl ether (DME) hydrocarbonylation was assessed by the authors [1], revealing that this indirect route is more cost-competitive than state of the art routes of bioethanol production [1]. This paper explores the potential of such a biorefinery by polygenerating high-value chemical products (methyl acetate and H 2 ), liquid transportation fuels (ethanol and DME) and electricity.…”

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).
