Increasing the succinate yield in Actinobacillus succinogenes by fumigation of H2 in a bioreactor

open access: yesBiofuels, Bioproducts and Biorefining, Volume 20, Issue 2, Page 591-605, March/April 2026.
Abstract The microbial conversion of CO2 into value‐added chemicals offers a promising and scalable route for sustainable bioproduction, particularly under mild reaction conditions and with technically straightforward reactor configurations. Actinobacillus succinogenes, a natural succinate producer, can fix CO2 through anaplerotic carboxylation but its

Experimental study on PM deposition behavior in an EGR cooler

open access: yesNihon Kikai Gakkai ronbunshu, 2014
Exhaust Gas Recirculation (EGR) system with EGR coolers is one of the promising ways for NOx reduction in a diesel engine. Since PM and condensable hydrocarbons are contained in the exhaust gas of a diesel engine, they cause PM deposition on the wall in ...

Combined Effect of Cetane Improver, Aluminum Oxide Nanoparticles, and Waste Cooking Oil Biodiesel Blend on a Dual Fuel Combustion Engine Run With Biogas Originated From Food Waste

open access: yesEnergy Science &Engineering, Volume 14, Issue 3, Page 1372-1386, March 2026.
Sugarcane juice is clarified and fermented with yeast to produce ethanol and CO₂. The broth is refined through distillation and molecular sieves, yielding fuel‐grade ethanol stored for transport. Bagasse, vinasse, and residues are recycled as valuable by‐products, enabling a sustainable bioethanol production pathway ABSTRACT This study investigates the

Increasing exhaust temperature to enable after-treatment operation on a two-stage turbo-charged medium speed marine diesel engine [PDF]

open access: yes, 2018
Nitrogen-oxides (NOx) are becoming more and more regulated. In heavy duty, medium speed engines these emission limits are also being reduced steadily: Selective catalytic reduction is a proven technology which allows to reduce NOx emission with very high
