Chapter
This chapter aims to clarify the main aspects of the dry reforming of methane (DRM), and how an efficient catalyst design can be the best way of minimizing constant concerns about the DRM process. Important aspects related to the coke deposition and active site sintering will be discussed in detail, once they are the main catalyst deactivation mech...
Article
In this work, limits and capacities of biotrickling filtration as a technique to compete with chemical scrubbing for the treatment of ammonia loads above 40 gN m⁻³ h⁻¹ are investigated. Long-term operation of a lab-scale biotrickling filter under different inlet NH3 concentrations (100 to 1400 ppmv) and gas contact times (2 to 46 sec) was performed...

Hydrogen sulfide removal from biogas was studied under anoxic conditions in a pilot-scale biotrickling filter operated under counter- and co-current gas-liquid flow patterns. The best performance was found under counter-current conditions (maximum elimination capacity of 140 gS m−3h−1). Nevertheless, switching conditions between co- and counter-cur...

BACKGROUND Biological oxidation in biotrickling filters of high H2S loads contained in biogas streams still requires further study to reduce elemental sulfur accumulation due to limited gas-liquid oxygen mass transfer inside biotrickling filters bed. Reduction of elemental sulfur accumulation may be improved by regulating the main manipulated varia...
Article
To explore the changes in the microbial community structure during the recovery process of an anammox reactor after a temperature shock, the 454-pyrosequencing technique was used. The temperatures shock reduced the nitrogen removal rate up to 92% compared to that just before the temperature shock, and it took 70 days to recover a similar nitrogen r...

tBiotrickling filters for biogas desulfurization still must prove their stability and robustness in the longrun under extreme conditions. Long-term desulfurization of high loads of H2S under acidic pH wasstudied in a lab-scale aerobic biotrickling filter packed with metallic Pall rings. Reference operating con-ditions at steady-state corresponded t...
Article
Pall rings, a common random packing material, were used in the biotrickling filtration of biogas with high H2S. Assessment of 600d of operation covered the reactor start-up, the operation at neutral pH and the transition from neutral to acid pH. During the start-up period, operational parameters such as the aeration rate and the trickling liquid ve...
Conference Paper
Full-text available
The application of "bio-omics" has been crucial to the development of environmental microbiology mostly for its comprehensive coverage. In this work, the 454 Roche platform was applied for massive sequencing of nucleic acids for studying metagenomics and metatranscriptomics of a biotrickling filter for H 2 S desulfurization under aerobic conditions...

Archived project
The project proposes the study and optimization of the biological oxidation of H2S under aerobic and anoxic conditions coupled to the control of the operation of the biorreactor, to the improvement of the oxygen mass transfer, the optimization of the operating conditions through the use of respirometric techniques, process modelling and a complete characterization of biorreactor microbial populations by means of molecular biology techniques. From data obtained in the systems developed along the project we will be able to optimize industrial treatment systems using both economical and ecological criteria in the treatment of real effluents with the collaboration of two companies interested in the project.
