Abstract: The invention discloses a method for producing bio-fuel (BF) from a high-viscosity biomass using thermo-chemical conversion of the biomass in a production line (10) with pumping means (PM), heating means (HM) and cooling means (CM). The method has the steps of 1) operating the pumping means, the heating means and the cooling means so that the production line is under supercritical fluid conditions (SCF) to induce biomass conversion in a conversion zone (CZ) within the production line, and 2) operating the pumping means so that at least part of the production line is in an oscillatory flow (OF) mode. The invention is advantageous for providing an improved method for producing biofuel from a high-viscosity biomass. This is performed by an advantageous combination of two operating modes: supercritical fluid (SCF) conditions and oscillatory flow (OF).

Abstract: Procedure and mechanism for the treatment, especially through heating of surfaces (8) on plastic objects, which are to be assembled/molded together, and which immediate before are molded or placed in the same special mold, which is equipped with at least one turnable mold part (1). This addition of heat/energy suitably takes place in the form of laser beams (9) or another corresponding precision radiation, that is directed towards at least one of the previous molded border surfaces (8), immediate before the following material is added/molded on. The surfaces (8) can hereby also by the treatment be deformed in chosen areas, which further can increase the adhesion. The invention further implies that you can achieve areas with respectively a good and a bad, or more correct no adhesion, which can be suitable at the production of certain objects.
