The present invention concerns a process and an apparatus for thermal conversion of biomass and organic wastes. According to the invention, the feedstock is fed into a fluidized-bed reactor, wherein the feed is converted at an elevated temperature under the influence of particulate matter kept in a fluidized state by a fluidizing gas, the particulate matter is transferred from the reactor to a regenerator for regeneration and then recirculated to the reactor after the regeneration, and the converted hydrocarbon products are recovered from the reactor. Both the reactor and the regenerator comprise risers having an axially annular cross section and being equipped with multi-inlet cyclones for the separation of particulate matter.

Medicines may also be applied over a large area of skin and during a long period of time to achieve desired treatments.

The energy content of supercapacitor is determined by its capacitance value and working voltage. To attain a high capacitance and a high voltage, several pieces of electrodes and separators are spirally wound with edge sealing to form a bipolar supercapacitor in cylindrical, oval or square configuration.

The bipolar roll is a powerful building block for facilitating the assembly of supercapacitor modules. Using containers with multiple compartments, as many bipolar rolls can be connected in series, in parallel or in a combination of the two connections to fabricate integrated supercapacitors with high energy density as required by applications.
