Hamburg University Pyrolysis Process, high-temperature pyrolysis of mixed plastics, using a fluid bed reactor. Demonstration plant at Ebenhausen has not survived shake-down, due to various operating problems. 

A plant operating according to the Hamburg University pyrolysis process was built at Ebenhausen, with a capacity of 5000 tonnes per year. The feasibility of converting poly-oleflns by pyrolysis was successfully demonstrated, with yields from PE/PP mixtures of typically 51% (m/m) gas, 42% (m/m) liquids and the balance unaccounted for. However, the gas to liquids ratio is very sensitive to pyrolysis temperature. Since gas and oil are the major pyrolysis products, economic viability crucially depends on the price of crude oil. Under present conditions, profitability and economic viability are unsatisfactory at this small scale of operation. 

Increase in thermal process temperature up to 685-715°C in a fluidized-bed system (Hamburg University Pyrolysis Process-HUPP) and application of a mixture of municipal plastic wastes resulted mainly in gaseous products, over 41 wt%, of which olefins constituted 15%, and aromatic (BTX)-containing liquid products [14], Considerably better results from the point of view of C2 and C3 olefins yield were obtained in other experiments. The application of steam as fluidization agent instead of circulation pyrolysis gas enabled an increase of C2-C3 olefins yield from 48 to 60%, accompanied by decrease in BTX yield from 24 to 11 wt% [15],...

During the past years, individual ions of barium and ytterbium have been prepared in the outlined way at Hamburg University in order to study the interaction of these ions with light and radio frequency radiation [38-43]. Some of this work was devoted to the very observation of the obstruction of a free ion s evolution by its repeated measurement [41-43]. An experiment on a single ytter-...
