Abstract null null In recent years, there have been many investigations carried on the regulated emissions in SI engines using gasohol fuels. However, there has been a lack of research on unregulated emissions, the technique required to reduce unregulated emissions, and cold start emissions at gasohol fuels. In this research work, a unique design for substrate in the catalytic converter is proposed to increase the conversion efficiency and reduce both regulated and unregulated emissions. The Com...

Abstract null null Hydrate reservoirs with underlying gas are generally accepted as the most promising energy resource for commercial exploitation. The underlying gas is an important part of the energy recovery of hydrate reservoirs. However, the gas production characteristics of hydrate reservoirs with underlying gas are rarely discussed. This paper aims to analyze the effects of underlying gas on the formation of hydrate and methane production behaviors by depressurization. In a core holder, m...
Abstract null null Mercury pollution from coal combustion has attracted widespread attention. Petroleum coke (PC), a by-product from petrochemical industry, is a potential substance to replace activated carbon mercury removal adsorbent. Most of the published articles on PC-based mercury removal adsorbent are reviewed in this work. It shows raw PC has little mercury removal ability (5%). Pyrolysis can increase mercury removal ability of PC with limited improvement effect (below 60%). KOH activati...

Abstract null null Catalytic dry reforming of methane is an attractive route for CO2 valorization that yields syngas (CO + H2) for subsequent synthesis of chemical and fuels. Alternatively, chemical looping approaches based on discontinuous cyclic operation are lately gaining relevance because, among other advantages, these processes are less prone to deactivation, and they are amenable to be used for thermosolar fuel production. With this background, here we investigate the isothermal activity ...

Abstract null null This review discusses the influence of three key factors on agglomeration of chemical looping technology from the aspects of reaction conditions, the oxygen carrier and biomass composition. In addition, the existing agglomeration mechanisms are extended, and the technologies of detection and prevention of the agglomeration is reviewed. In the process of chemical looping reaction, high reaction temperature, the oxygen carrier materials with poor anti-sintering ability and the r...
Abstract null null Coal chemical looping gasification (CCLG) is a promising gasification technology for coal utilization with high resource utilization rate, energy saving and environmental protection properties. Development of suitable oxygen carriers and optimization of operating conditions for CCLG are the key for the coal conversion and H2&CO production (H2, CO). In this study, Cu-Fe bi-ore oxygen carrier prepared by spray drying granulation method using hematite and copper ore as raw materi...

Abstract null null Beside numerous chemical methods, biological methods were developed to remove sulfide from streams using Sulfur Oxidizing Bacteria (SOB). Because of the wide variety of such bacteria and deep difference in their capability, the ability of seven well-known SOBs were investigated. According to the results T. versutus and T. aerophilum were selected as capable bacteria for further experiments. The valuable product of sulfide oxidation is elemental sulfur, the production of sulfur...
