Doctorate at Chemical Engineering from Universidade Federal de São Carlos (1988) and Ph.D. at Chemical Engineering from Universidade de São Paulo (1994). Has experience in Chemistry, acting on the following subjects: steam reforming, dry reforming and partial oxidation of methane, ethanol and glycerol steam reforming, acetic acid steam reforming, CO and CO2 hydrogenation, shift and prox-CO reaction. The catalysts are prepared and characterized and are based in Ni, Co and Cu supported on CeO2, Al2O3. SiO2, ZrO2, perovskites, hydrotalcites and others. (Source: Lattes Curriculum)
In this project, the glycerol obtained in the biodiesel chain will be used as a renewable raw material to obtain hydrogen by steam reforming. Nickel and cobalt catalysts derived from perovskite type structures and also dispersed in the Ce-La / SiO2 supports will be developed. We are expected that the catalysts to be active, selective and resistant to coke deactivation. Research groups fro…
The main goal of this Research Project is to establish the fundamental bases to apply the biorefinery concept to a biological wastewater treatment plant, with generation of bioenergy and high value-added products. Such conception is based on the use of anaerobic reactors as the core technology in a wastewater treatment plant, mainly because this process generates a broad spectrum of organ…
The FAPESP - BG BRASIL RESEARCH CENTRE FOR GAS INNOVATION (FAPESP-BG/CEPID) aims to build up a new world class Centre for Advanced Natural Gas Studies, which will focus on the sustainable uses of natural gas in the coming years. The Centre complements Fapesp's experiences in supporting high-level scientific research and technology development in energy fields. It aims to establish a world…
The advances of the last few years in the municipal and industrial wastewater biological treatment have been supported by basic and applied research involving mainly the fundamental aspects of the processes and the development of innovative bioreactors. A sound and thorough knowledge of the basic phenomena, together with the development of the engineering of biological reactors have opene…
Studies exploring the enhancement of catalytic systems for the conversion of methane into higher value-added chemicals have been received attention due to large natural gas reserves and the reduction of fossil fuel. In this perspective, the oxidative coupling of methane demonstrates to be interesting to produce ethylene, for example. It is known that ethylene plays a key role in the produ…
Currently, methanol, one of the main products of interest in the chemical industry, is produced from the synthesis gas (CO/H2) in a high pressure process (50-100 bar) using Cu/ZnO/Al2O3 as catalyst. The increase in world demand for methanol predicted for the next years makes necessary the development of alternative, selective and low cost processes for its synthesis. An alternative route …
The use of methane generated in treatment of wastewater via oxidative coupling (AOM), in which occurs the direct conversion to ethene, eliminates the formation of synthesis gas and conversion in methanol followed by dehydration to ethene. During indirect conversion, the major part of the invested capital is associated to the generation of the synthesis gas, which makes the oxidative coupl…
The abundance, low cost and environmental concerns related to emission of methane into the atmosphere have intensified research for valorization of this gas in recent years. Currently, processes that efficiently convert methane to alcohols or olefins are complex and costly, because they require the intermediate step of reforming methane to synthesis gas (CO and H2). Due to the difficultie…
Wastewater and sewage treatment systems are increasingly important in terms of sustainable management of current water resources. Despite the great efficiency of these systems, some aspects still need to be improved such as the search for appropriate destination for the biogas components generated in the process. The biogas consists mainly of CO2 and CH4, greenhouse gases whose atmospheri…
The development of hydrogen generation technologies has been growing in recent years in response to heightening concerns about the environmental impact of energy use and worries about the security of fossil-fuel supplies. In addition, the hydrogen can be obtained from renewable raw materials. Standing out among these technologies is the steam reforming of bio-oil from the pyrolysis of bio…

Much effort has been devoted to the generation of more sophisticated synthesis methods to obtain particles with as specific composition, size and morphology as possible. In this sense, one of the most promising synthesis techniques is atomic layer deposition (ALD). Unlike conventional methods, ALD allows the generation and growth of precision-controlled atomic-level nanoparticles and film…
Recently materials containing atomically dispersed noble metal have shown to be an efficient and economical way to improve productivity on diverse catalytic systems. Rh and Pd single sites are found to be active to partially oxidize methane into methanol by efficiently stabilizing CH3 intermediates when related to nanoparticles. The rational design of catalysts with precisely controlled i…
This proposal for international collaboration aims to accomplish part of my postdoctoral entitled "Oxidative Coupling of Methane using A2B2O7 catalysts" funded by the FAPESP grant 2019/10980-9 and the thematic project entitled "Biorefinery Concept Applied to Biological Wastewater Treatment Plants: Environmental Pollution Control Coupled with Material and Energy Recovery" FAPESP grant 2015…
Atomic layer deposition (ALD) is a surface technique that can be used to prepare materials with improved characteristics on the atomic scale. The application of this technique for the design of catalysts has already proven effective in improving catalytic activity, selectivity, and stability, modifying the traditional synthesis techniques to maximize the reactive surface area of the mater…
