Abstract

An attractive simplification of PEM-FC systems operated with natural gas would be the use of a sulfur tolerant reforming catalyst, but such a catalyst has not been available thus far. In this work it is demonstrated that a tailor made rhodium catalyst retains useful activity for typical sulfur levels in the feed. A brief economic comparison showed however that this alternative process is still less economical than the traditional process employing removal of sulfur components by adsorption.

Abstract

Navigating the Future draws on long-term ethnographic fieldwork with Kubo people and their neighbours, in a remote area of Papua New Guinea, to explore how worlds are reconfigured as people become increasingly conscious of, and seek to draw into their own lives, wealth and power that had previously lain beyond their horizons. In the context of a major resource extraction project—the Papua New Guinea Liquefied Natural Gas (PNG LNG) Project–taking shape in the mountains to the north, the people in this area are actively reimagining their social world. This book describes changes in practice that result, tracing shifts in the ways people relate to the land, to each other and to outsiders, and the histories of engagement that frame those changes. Inequalities are emerging between individuals in access to paid work, between groups in potential for claiming future royalties, and between generations in access to information. As people at the village of Suabi strive to make themselves visible to the state and to petroleum companies, as legal entities entitled to receive benefits from the PNG LNG Project, they are drawing new boundaries around sets of people and around land and declaring hierarchical relationships between groups that did not exist before. They are struggling to make sense of a bureaucracy that is foreign to them, in a place where the state currently has minimal presence. A primary concern of Navigating the Future is with the processes through which these changes have emerged, as people seek to imagine—and work to bring about—a radically different future for themselves while simultaneously reimagining their own past in ways that validate those endeavours.

Abstract

Barely known in public is the life of long-distance commute workers who extract the „blue and black gold” for the export to Europe. They are travelling people who work and live rotationally for a few weeks at the extraction sites before they go back again to their families in the southern regions. This ethnography takes the reader from the Volga Region to the Arcitc “Russian Gas Capital” Novy Urengoy and provides critically insights into the Russian petroleum industry.

Abstract

Catalyst lifetime represents one of the most crucial economic aspects in industrial catalytic processes, due to costly shutdowns, catalyst replacements, and proper disposal of spent materials. Not surprisingly, there is considerable motivation to understand and treat catalyst deactivation, poisoning, and regeneration, which causes this research topic to continue to grow. The complexity of catalyst poisoning obviously increases along with the increasing use of biomass/waste-derived/residual feedstocks and with requirements for cleaner and novel sustainable processes. This book collects 15 research papers providing insights into several scientific and technical aspects of catalyst poisoning and deactivation, proposing more tolerant catalyst formulations, and exploring possible regeneration strategies.

Abstract

Climate change is one of the main threats to modern society. This phenomenon is associated with an increase in greenhouse gas (GHGs, mainly carbon dioxide—CO2) emissions due to anthropogenic activities. The main causes are the burning of fossil fuels and land use change (deforestation). Climate change impacts are associated with risks to basic needs (health, food security, and clean water), as well as risks to development (jobs, economic growth, and the cost of living). The processes involving CO2 capture and storage are gaining attention in the scientific community as an alternative for decreasing CO2 emissions, reducing its concentration in ambient air. The carbon capture and storage (CCS) methodologies comprise three steps: CO2 capture, CO2 transportation, and CO2 storage. Despite the high research activity within this topic, several technological, economic, and environmental issues as well as safety problems remain to be solved, such as the following needs: increase of CO2 capture efficiency, reduction of process costs, and verification of the environmental sustainability of CO2 storage.

Abstract

This Special Issue reports research spanning from the analysis of indirect data, modeling, and laboratory and geological data confirming the intrinsic multidisciplinarity of gas hydrate studies. The study areas are (1) Arctic, (2) Brazil, (3) Chile, and (4) the Mediterranean region. The results furnished an important tessera of the knowledge about the relationship of a gas hydrate system with other complex natural phenomena such as climate change, slope stability and earthquakes, and human activities.
