Abstract: Recently, non-thermal food processing utilizing an underwater shockwave has been receiving much attention to provide nutritious and fresh foods at low cost. To generate the underwater shockwave, we propose a series-connected high voltage multiplier with bipolar structure. Unlike conventional Cockcroft-Walton voltage multipliers (CWVMs), the proposed multiplier amplifies the input voltage twice by connecting positive/negative multiplier blocks in series. Furthermore, these multiplier blocks are driven by high speed rectangular pulses. Owing to the series-connected bipolar topology, the proposed multiplier can achieve not only high conversion ratio but also high response speed. The operation principle and characteristic evaluation are described concerning the proposed multiplier. Simulation program with integrated circuit emphasis (SPICE) simulations demonstrate the feasibility and effectiveness of the proposed multiplier.

Abstract: Recycling of polymer waste is important both in the conservation of resources and the environment. A plastic waste was pyrolyzed over a series of post-use commercial catalysts using a fluidizing reaction system. Experiments carried out with these catalysts gave good yields of valuable hydrocarbons with differing selectivity in the final products text. Greater product selectivity was observed with a hybrid catalyst of MCM-41/Cat- R1 with more than 65.8 wt% olefins products.
