It is generally known that production of methanol (MeOH) from biomass and from carbon dioxide and hydrogen does not involve experimental technologies. Almost identical proven and fully commercial technologies are used to make MeOH from fossil fuel-based syngas and can be used for renewable MeOH production.
Traditional MeOH synthesis technologies rely on low-pressure methods, which require complex production steps starting from feedstock purification, turning it into synthesis gas, producing crude MeOH, separating it from water and other components and repeating the cycles multiple times to achieve desired process efficiencies.
With our method we eliminate the syngas phase achieving a direct conversion. We accept higher feedstock impurities, which also reduces feed-stock conditioning and distillation phases. Where others use multiple reactors, compressors, columns, drums, boilers and etc., we achieve 95%+ CO2 conversion, 98% methanol selectivity and 95%+ methanol yield in a single step with singe smaller reactor and compressor.
Our know-how also delivers increased catalyst performance of up to 15g of MeOH per 1g of catalyst (1:15) vs 1:1 in case of conventional methods.
Together with already available flue gases capture technologies our solution can be retrofitted into an existing facility, eliminating the need to redesign the plant’s processes while meeting emission reduction targets and extending asset useful lifetime in an economically attractive way.
At the same time our high-pressure method can be a value adding part to Power-to-Methanol projects with direct air capture systems reducing the final product costs through higher conversion efficiencies.
Methanol or, alternatively, dimethyl ether (DME) are the key products of our direct synthesis. Further downstream conversion to other methanol-based products is possible depending on the CCU project specifics and off-taking arrangements.
Methanol is a key product in the chemical industry. It is mainly used for producing other chemicals such as formaldehyde, acetic acid and plastics. Methanol is also a versatile fuel that can be used in internal combustion engines, and in hybrid and fuel cell vehicles and vessels. Liquid at ambient temperature and pressures, it is straightforward to store, transport and distribute, making it compatible with existing distribution infrastructure and blending with conventional fuels to create high- performance and low-carbon fuels.
Around 100 million tonnes (Mt) of methanol are produced per annum, nearly all of it comes from fossil fuels (either natural gas or coal). Only about 0.2 Mt of renewable methanol is produced annually. Renewable methanol can be made from a variety of sustainable feedstocks, such as biomass, waste or CO2 and hydrogen. Its use in place of fossil fuels will reduce greenhouse gas (GHG) emissions and in some cases can also reduce other harmful emissions (sulphur oxides [SOx], nitrogen oxides [NOx], and particulate matter [PM]).
