      Pyrolytic biodiesel from plant oil asphalt: The cover image shows a scheme for the conversion of plant oil asphalt into pyrolytic biodiesel by using vacuum pyrolysis. Plant oil asphalt is the black, dense, highly viscous liquid product generated in the biodiesel or fatty-acid industries. Plant oil asphalt is currently an underutilized lipid-based biomass residue. In the process described by Jinfu Wang and colleagues at Tsinghua University on page 512, the plant oil asphalt can be transformed into 70 wt % pyrolytic oil by vacuum pyrolysis and then further upgraded to pyrolytic biodiesel, which is a mixture of fatty-acid methyl esters, paraffins, cycloparaffins, olefins, and aromatics. The pyrolytic biodiesel exhibits a clear pale yellow color and excellent storage stability.

      Carrying the load: Hydrogen is expected to become a major energy carrier, but its storage is still challenging. Numerous technologies and suggestions for solving this problem have appeared in recent years. This review gives an overview of the advantages and disadvantages of different concepts in hydrogen storage, focusing on the primary aspects of storage density and efficiency.

    1. Pyrolytic Biodiesel Production by Vacuum Pyrolysis of Fatty-Acid Residue as Plant-Oil Asphalt (pages 512–518)

      Qiang Tang, Yanyan Zheng and Prof. Dr. Jinfu Wang

      Trimming the fat: Fatty-acid residue as plant oil asphalt (FA-POA) is an underutilized lipid-based biomass residue. FA-POA can be transformed into over 70 wt % pyrolytic oil by vacuum pyrolysis, with cogeneration of biogas and biochar. The pyrolytic oil is upgraded to pyrolytic biodiesel, which is a mixture of fatty acid methyl esters, paraffins, cycloparaffins, olefins, and aromatics.

    2. Determination of Methane-Hydrate Phase Equilibrium in the Presence of Electrolytes or Organic Inhibitors by using a Semi-Theoretical Framework (pages 519–529)

      Cleaning out the pipes: The formation of hydrates in natural-gas pipelines can lead to the dangerous conditions of pipeline blockage and rupture. A thermodynamic-based procedure is developed that is capable of predicting the behavior of various methane-hydrate-formation inhibitors (including aqueous solutions of salts and organic inhibitors) and the results are compared with experimental data from the literature.

    3. Effects of Different Surfactants on the Kinetics of Ethane-Hydrate Formation: Experimental and Modeling Studies (pages 530–536)

      Turning up the volume: The use of gas hydrates allows for the storage of 150–180 volumes of gas for each volume of hydrate, and this could be particularly useful for natural gas storage. The effects of the stirring rate, initial pressure, and concentration of various surfactants (anionic, cationic, and nonionic) were investigated on the kinetics of ethane-hydrate formation for this purpose.

    4. Effects of Antioxidants on the Cetane number, Viscosity, Oxidation Stability, and Thermal Properties of Biodiesel Produced from Nonedible Oils (pages 537–543)

      Increasing the shelf life: Biofuels derived from plants of African origin (Moringa oleifera, Jatropha curcus, and Croton megalocarpus) are studied for their oxidation stability with and without the addition of antioxidant molecules. The addition of antioxidants to biodiesel is found to lengthen storage time of the biodiesels and also improve the fuel properties, such as the kinematic viscosity, thermal properties, and cetane number as an added advantage.

    5. Characteristics of Alkali and Alkaline-Earth Metals for the Catalytic Gasification of Coal Char in a Fixed-Bed Reactor (pages 544–550)

      Prof. Yifei Wang, Dr. Weilong Jin, Taohua Huang, Dr. Longchu Zhu, Chaoqi Wu and Prof. Guangsuo Yu

      Version of Record online: 3 SEP 2013 | DOI: 10.1002/ente.201300071

      Catalytic gasification: The effects of reaction temperature, catalyst type, and catalyst loading on the gasification of coal char with carbon dioxide are investigated in a fixed-bed reactor. The potassium-based catalysts are found to have the highest activity and could be used to enable coal gasification at lower temperatures.
