In this work, the effect of ash activated olivine on olefinic products cracking and aromatization was assessed. The experiments were carried out in Chalmers 2–4 MWth dual fluidized bed gasifier, where feedstock cracked using steam as fluidization agent, at a reaction temperature ca. 780–790 °C. Three activation states olivine, representing three consecutive days campaign, evaluated. changes per...

Laser beam powder bed fusion (PBF-LB) additive manufacturing (AM) is an advanced technology that manufactures metal components in a layer-by-layer manner. The thermal residual stress (RS) induced by the repeated heating–melting–cooling–solidification processes of AM considered to limit wider uptake PBF-LB. A dual-laser PBF-LB strategy, with additional auxiliary laser and reduced power, working ...
