Because of the limited resources of fossil fuels the efficient use of renewable energy is gaining importance. Renewable energy from biomass reduces CO 2 emissions, which is a necessity to protect the global climate. In the dual fluidized bed steam gasifier, wood chips are converted to producer gas, which is further used for heat, power, and/ or other product generation very successfully. This work presents alternative feedstocks for this process: biomass wastes, such as waste wood and bark. Waste wood and bark have been gasified successfully and results of these experiments in a pilot plant are presented in this paper.

The so‐called plug & play reactor is a novel reaction device with exchangeable reaction segments as well as modules for heating/cooling and mixing. Its performance is demonstrated for two model processes: the production of acetylsalicylic acid with a fixed bed of commercial ion‐exchange particles and a Suzuki‐Miyaura cross‐coupling with a solid Pd‐catalyst developed by us. The reaction progress was monitored by inline UV‐vis spectroscopy and compared with offline HPLC. The novel set‐up leads to quantitative yields and selectivity as well as to an improved practicability of the processes.

Microstructured reactors are the ideal device for highly exothermic reactions. In this work, the highly exothermic two-phase reaction of valeraldehyde with oxygen to valeric acid was carried out in a microreactor. The used device from one-A Engineering Austria GmbH is designed for process development and intensification and can be applied in the scale-up process to small-scale commercial production. The atom economic oxidation of valeraldehyde is performed at 0 to 40 °C with a catalytic amount of manganese­(II) acetate. A continuous flow oxidation of aldehydes in such reactors can be a safe and beneficial alternative to commercial batch processes.
