CONTROLLED CATALYTIC AND THERMAL SEQUENTIAL PYROLYSIS AND HYDROLYSIS OF MIXED POLYMER WASTE STREAMS TO SEQUENTIALLY RECOVER MONOMERS OR OTHER HIGH VALUE PRODUCTS

摘要

process of using a fast pyrolysis in a carrier gas to convert a power supply of a polymer composition of mixed waste plastics so that the pyrolysis of a polymer, a monomer constituent value is carried out prior to pyrolysis all plastic components in the current.the process is: to select a first range of temperature programming for the pyrolysis of the polymer and monomer conversion in a constituent value before selecting a temperature range causing the other plastic pyrolysis choose a catalyst, and to deal with the common carrier food using itin order to establish talyseur reaction course in basic or acidic catalysis and to maximize the efficiency and improve the separation of the constituent monomer of high value in the range of temperatures and heat flow in a differential manner the chal intensity eur in the first range of programming to perform pyrolysis temperature differentialand get an optimal amount of selectively valuable constituent monomers prior to the pyrolysis of plastic elements, to separate the components of high value to select monomer; a second temperature range which is higher the pyrolysis of a constituent monomer different from value of plastic wasteand heat in the power supply (over a range of temperature for the pyrolysis of different component, and separating it.
