The main advantage of visualizing multiphase flow in a drilling annulus is that the viewer can easily distinguish fluid phases, flow patterns and thicknesses of cutting beds. Hence, catalytic steam reforming is an effective technique to address tar formation and improve H2 production from biomass gasification. Micro/nanostructures play a key role in tuning the radiative properties of materials and have been applied to high-temperature energy conversion systems for improved performance. The concept of dynamic permeability and characterization of the permeability of NGH by time-varying equations should be established. The synergistic or inhibitory effects of the combinations of these additives are also analyzed. However, the empirical evidence on the relationship between financial development and energy intensity remains sparse in the literature. Although great progress has been made in the exploitation of natural gas hydrate, there still exist enormous challenges in basic theory research, production methods, and equipment and operation modes. A thermodynamic model has been established to analyze the coupled heat transfer characteristics of HGMs and VCS in the composite insulation system. The comparison of the results shows the benefits of MOPSO in optimizing dish Stirling finite time thermodynamic equations. Recently, renewable energy resources and their impacts have sparked a heated debate to resolve the Australian energy crisis. Another significant advantage of HGMs is that their thermal insulation properties are not sensitive to ambient vacuum change. In this paper, a novel coal and biomass indirect coupling system is proposed based on the technology of biomass gasification and co-combustion of coal and gasification gas. There are various analyses for a solar system with the dish-Stirling technology. Scope & Mission. Foaming, however, could not be avoided during hydrate dissociation with the presence of SDS. The results show that when the mass concentration of fullerenes nanocomposite is higher than 60 ppm and the concentration of nano-oil is 2 g/L, the friction coefficient decreases from 0.13 to 0.06 which means the wear is reduced. This paper focuses on the current researching status, prospects, and challenges of steam reforming of gasified biomass tar. As a new clean energy resource in the 21st century, natural gas hydrate is considered as one of the most promising strategic resources in the future. However, evaporation loss is a serious problem in LH2 storage due to the low boiling point (20 K). This paper aims to review the current status of different renewable energy resources along with their impacts on society and the environment. In this paper the hole cleaning process which involves the transportation of cuttings through a horizontal annulus was studied. Gasification is a thermo-chemical reaction which converts biomass into fuel gases in a reactor. LNG is heated by seawater and the intermediate fluid in these heat exchangers. Field Chief Editor Professor Uwe Schröder, from Braunschweig University of Technology leads an outstanding Editorial Board of international experts. This paper presents an overview of the spectral emittance measurement techniques using both the direct and indirect methods. The first step in the conversion process is the selection of a suitable feedstock capable of generating more gaseous fuels. Parametric studies are conducted to analyze the effect of temperature, steam to biomass ratio and equivalence ratio on energy and exergy efficiencies. The journal is particularly focused on addressing technological advances which support Sustainable Development Goal #7: access to affordable, reliable, sustainable and modern energy for all. When the blending ratio of biomass is 20%, the energy and exergy efficiencies of the indirect coupling system are 42.70% and 41.14%, the internal rate of return (IRR) and discounted payback period (DPP) of the system are 25.68% and 8.56 years. The ‘Three-gas co-production’ (natural gas hydrate, shallow gas, and conventional gas) may be an effective way to achieve early commercial exploitation. The heaving wave energy converter (WEC) is one typical type of point absorber WECs with high energy conversion efficiency but significantly affected by the viscous effect. Methane hydrate preparation is an effective method to store and transport methane. The price fluctuation of fuels and products has a great influence on the economic performance of the indirect coupling system. The algorithm of multi-objective particle swarm optimization (MOPSO) with post-expression of preferences is used for multi-objective optimizations while the branch and bound algorithm with pre-expression of preferences is used for single-objective and multi-objective optimizations. This paper provides a comprehensive source of information for the application of micro/nanostructures in high-temperature energy conversion engineering. Furthermore, the effects of NH3BH3 concentration (0.1–50 mmol/5 mL), catalyst amount (1–30 mg) and temperature (20°C–50°C) on the rate of H2 production and the effects of temperature (20°C–50°C), NH3BH3 concentration (0.05–1 mol/L) and catalyst amount (0.5–5 µL) on the electro-oxidation reaction of NH3BH3 were investigated using the central composite design experimental design. A quasi-equilibrium model is developed to simulate and compare the feasibility of different biomass materials as gasifier feedstock. The key technologies of liquefied hydrogen have been developing rapidly due to its prospective energy exchange effectiveness, zero emissions, and long distance and economic transportation. Besides, the factors influencing surfactant-promoted hydrate formation, including the type, concentration, and structure of the surfactant, are also described. 京ICP备12020869号-1　京ICP证150856号　 京公网安备 11010202008535号, Service: 010-58556313 (Technology); 010-58556485 (Subscription) E-mail: [email protected], Shouwei ZHOU, Qingping LI, Xin LV, Qiang FU, Junlong ZHU, Quan CAO, Dongyan XU, Huanfei XU, Shengjun LUO, Rongbo GUO, Bojie WANG, Wen WANG, Chao QI, Yiwu KUANG, Jiawei XU, Zhen PAN, Yi WU, Liyan SHANG, Li ZHOU, Zhien ZHANG, Shiquan SHAN, Chuyang CHEN, Peter G.
