Six different processes for the direct methanation of biogas for biomethane production were evaluated regarding their economically optimised operating conditions, their absolute costs and profitability. Detailed process simulations turned out to be important…

Domestic and imported biomass or biofuels used for energy purposes play an important role in many future energy scenarios and national policies. But both the realizable potential for biomass and the environmental consequences of its deployment for…

A multivariate calibration method for mass spectrometry is presented that enables a quantitative analysis of gas mixtures containing interfering gases that contribute to the same mass-to-charge ratios at nominal resolution. Multiple calibration gas mixtures with…

In this work, we systematically investigated factors governing catalytic oxidation of Kraft lignin in a biphasic system at acidic conditions. The process is designated biphasic depolymerization (BPD) and is based on the concept of protective extraction of the target…

Direct methanation of biogas is a promising application of the Power-to-Gas concept, since up to 80% more methane can be produced in comparison to conventional biogas upgrading methods. Six different processes, in which a bubbling fluidized bed or a fixed…

The coupling between a scanning mobility particle sizer (SMPS) and an inductively coupled mass spectrometry (ICP-MS) was in the past shown to obtain simultaneous size-resolved and elemental information on nanoparticles, using a rotating disc diluter (RDD) as conditioning and dilution system…
