Carbon capture and storage (CCS) is an essential greenhouse gas removal (GGR) technology used to achieve negative emissions in bioenergy plants using biomass feedstock (Bio-CCS). In this study, the climate mitigation potential of a novel GGR technology consisting in the production of renewable-derived plastics from municipal solid waste (MSW)...

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...

Thermochemical biorefinery based on dimethyl ether (DME) as an intermediate is studied. DME is converted into methyl acetate, which can either be hydrogenated to ethanol or sold as a co-product. Considering this option together with a variety of technologies for syngas upgrading, 12 different process concepts are analyzed. The considered...

In this study, a new thermochemical route to produce lignocellulosic ethanol based on DME (dimethyl ether) hydrocarbonylation is proposed and economically assessed. The process is designed and evaluated using current kinetic laboratory data for hydrocarbonylation reactions. Only available technologies or those expected to be available in the...

The accreditation of engineering programmes is a subject of great interest in the last decades. However, most studies in the literature are focused on case studies or deal with the different levels of acceptance of the groups involved in the accreditation. There are two main approaches for the accreditation of engineering programmes, i. e., at...

This paper studies key issues for the design of industrial ethanol to 1,3-butadiene two-step processes, focusing on the second catalytic reaction step, for which a Ta-SBA-15 catalyst was chosen as a representative of the new generation of two-step catalysts. The important practical aspects studied were: i) the effect of operating conditions and...

The production of higher alcohols (C≥4) via ethanol liquid-phase condensation over different Cu-based catalysts is studied in this work. Experimental results demonstrate that dehydrogenation steps are more relevant than hydrogenation steps, according to the lack of improvement in activity when a bimetallic (Pd-Cu) catalyst. Thus, the sequential...

Hydrogen is not only considered as a cornerstone within renewable energy portfolio but it is also a key enabler for CO2 valorisation being a central resource for industrial decarbonization. This work evaluates the profitability of hydrogen production via combined biogas reforming and water–gas shift reaction, based on a real case scenario for...
