Growing energy demand, depleting fossil fuels resources as well as ecological concerns are the main rationales behind the research focused on broader utilization of biowaste, e.g. sewage sludge in energy systems. Gasification as an alternative to combustion offers increased efficiency, lower negative environmental impact and wider application range of the main product ? synthesis gas ? in power generation and chemical synthesis. It is also considered as one of the most viable options for hydrogen production, as an...

The article deals with of a hydrogen pressure vessel suitable for high pressure of approximately 75 MPa. One of the goals is to design a vessel from materials whose strength will meet mechanical requirements a calculated in both analytical and numerical ways. Another objective is the simulation of the design the pressure vessel with regard to safety and weight requirements.

The solubility of gases in liquid is an important parameter required for the interpretation of rate data in gas-liquid, gas-liquid-liquid and gas-liquid-solid reactions. Gas-liquid mass transfer plays an important role in many industrial processes, e.g. methanol synthesis. The overall rate of gas-phase and gas-liquid phase reactions strongly depends on mass transfer. A large number of solubility data of hydrogen and carbon monoxide in a variety of solvents is available in the literature, but the data on the gas so...
