Patent number: 11905478Abstract: A process for the manufacture of a useful product from carbonaceous feedstock of fluctuating compositional characteristics, the process comprising the steps of: continuously providing the carbonaceous feedstock of fluctuating compositional characteristics to a gasification zone; gasifying the carbonaceous feedstock in the gasification zone to obtain raw synthesis gas; sequentially removing ammoniacal, sulphurous and carbon dioxide impurities from the raw synthesis gas to form desulphurised gas and recovering carbon dioxide in substantially pure form; converting at least a portion of the desulphurised synthesis gas to a useful product. Despite having selected a more energy intensive sub-process i.e. physical absorption for removal of acid gas impurities, the overall power requirement of the facility is lower on account of lower steam requirements and thereby leading to a decrease in the carbon intensity score for the facility.Type: GrantFiled: February 28, 2023Date of Patent: February 20, 2024Assignee: Velocys Technologies Ltd.Inventors: Ivan Philip Greager, Roger Allen Harris, Neil Alexander King, Soumitra R.

Patent number: 11173483Abstract: A catalyst is regenerated by an inventive process using a heat exchange fluid such as superheated steam to remove heat during the process relying on efficient heat transfer (e.g., enabled by the microchannel reactor construction) in comparison with prior art heat exchange relying on a phase change, e.g. between water and (partial or complete vaporization) steam, allows simplification of the protocols to enable transition at higher temperatures between steps which translates in reduced duration of the regeneration process and avoids potential water hammering risks.Type: GrantFiled: June 4, 2020Date of Patent: November 16, 2021Assignee: VELOCYS TECHNOLOGIES LIMITEDInventors: Soumitra R.
