Research Abstract

New waste treatment was developed, Which converts organic wastes to hydrogen and carbon dioxide using supercritical water and CO2. The process is given by
Organic waste+Supercritical water>Hydrogen+Methane+CO2
Supercritical CO2+Cyclic ether>Cyclic carbonate
(1)Analysis of gasification of organic wastes in supercritical water
Using cross-linked polyethylene, polyurethane, ABS resin, livestock excrement, tofu refuse and paper sludge, the effect of temperature, pressure, reaction time and catalyst on the productivity of hydrogen and methane was investigated. As a result, (1)the optimum condition was 700℃, 10MPa, 20 min of the reaction time, (2)the catalytic activity was alkali<nickel catalyst for waste plastic and nickel<alkali catalyst for waste biomass containing sulfur or chlorine atoms, (3)the productivity of hydrogen was 3500 cm^3/g of cross-linked polyethylene and 1600cm^3/g of livestock excrement, (4)the hydrogen production was 2-5 times higher than that of convenience methods.
(2)Analysis of carbonate synthesis using supercritical CO_2
Supercritical CO_2 produced in gasification process reacted with cyclic ether with different membered ring to produce cyclic carbonate in the presence of LiBr catalyst. As a result, (1)the yield of three-membered ring carbonate was 90%, that of four-membered ring carbonate was 68%, and that of five-membered ring carbonate was zero, that is, cyclic ether with large steric stress gave excellent reactivity and yield, and (2)the optimal condition of the synthesis of propylene carbonate was 80℃, 15MPa, 0min.
