Biogas upgrading to biomethane as a local source of renewable energy to power light marine transport: Profitability analysis for the county of Cornwall
(Elsevier, 2022-01)
In this work, the use of biomethane produced from local biogas plants is proposed as renewable fuel for light marine transport. A profitability analysis is performed for three real biogas production plants located in ...

Exploring the regeneration of mordenite catalyst in dimethyl ether carbonylation reaction
(Universidad Autónoma Metropolitana, Unidad Iztapalapa, 2020)
Dimethyl ether carbonylation (DME) to produce methyl acetate (MA) over mordenite catalysts is attracting much attention because of its high selectivity. However, acidic mordenite suffers from a fast deactivation (coking) ...

Methodological development for the optimisation of electricity cost in cement factories: the use of artificial intelligence in process variables
(Springer Science and Business Media Deutschland GmbH, 2022)
Cement factories require large amounts of energy. 70% of the variable cost goes to energy—33% to kiln thermal energy and 37% to electrical energy. This paper represents the second stage of a broader research study which ...

Tar conversion of biomass syngas in a downstream char bed
(Elsevier, 2020)
The catalytic conversion of biomass-derived tars over char during long tests (over 6 h) is studied. The syngas is generated in a steam-blown fluidized-bed gasifier employing wood pellets and conducted to a second tubular ...
