| 520 | |a Abstract A new coal staged conversion poly-generation system combined coal combustion and pyrolysis has been developed for clean and high efficient utilization of coal. Coal is the first pyrolysed in a fluidized pyrolyzer. The pyrolysis gas is then purified and used for chemical product or liquid fuel production. Tar is collected during purification and can be processed to extract high value product and to make liquid fuels by hydro-refining. Semi-coke from the pyrolysis reactor is burned in a circulating fluidized bed (CFB) combustor for heat or power generation. The system can realize coal multi-product generation and has a great potential to increase coal utilization value. A 1 MW poly-generation system pilot plant and a 12 MW CFB gas, tar, heat and power poly-generation system was erected. The experimental study focused on the two fluidized bed operation and characterization of gas, tar and char yields and compositions. The results showed that the system could operate stable, and produce about 0.12 $ m^{3} $/kg gas with 22 MJ/$ m^{3} $ heating value and about 10 wt% tar when using Huainan bituminous coal under pyrolysis temperature between 500 and 600 °C. The produced gases were mainly $ H_{2} $, $ CH_{4} $, CO, $ CO_{2} $, $ C_{2} %$ H_{4} $, $ C_{2} %$ H_{6} $, $ C_{3} %$ H_{6} $ and $ C_{3} %$ H_{8} $. The CFB combustor can burn semi-coke steadily. The application prospect of the new system was discussed. | ||

Abstract A new coal staged conversion poly-generation system combined coal combustion and pyrolysis has been developed for clean and high efficient utilization of coal. Coal is the first pyrolysed in a fluidized pyrolyzer. The pyrolysis gas is then purified and used for chemical product or liquid fuel production. Tar is collected during purification and can be processed to extract high value product and to make liquid fuels by hydro-refining. Semi-coke from the pyrolysis reactor is burned in a circulating fluidized bed (CFB) combustor for heat or power generation. The system can realize coal multi-product generation and has a great potential to increase coal utilization value. A 1 MW poly-generation system pilot plant and a 12 MW CFB gas, tar, heat and power poly-generation system was erected. The experimental study focused on the two fluidized bed operation and characterization of gas, tar and char yields and compositions. The results showed that the system could operate stable, and produce about 0.12 $ m^{3} $/kg gas with 22 MJ/$ m^{3} $ heating value and about 10 wt% tar when using Huainan bituminous coal under pyrolysis temperature between 500 and 600 °C.

Coal is the first pyrolysed in a fluidized pyrolyzer. The pyrolysis gas is then purified and used for chemical product or liquid fuel production. Tar is collected during purification and can be processed to extract high value product and to make liquid fuels by hydro-refining. Semi-coke from the pyrolysis reactor is burned in a circulating fluidized bed (CFB) combustor for heat or power generation. The system can realize coal multi-product generation and has a great potential to increase coal utilization value. A 1 MW poly-generation system pilot plant and a 12 MW CFB gas, tar, heat and power poly-generation system was erected. The experimental study focused on the two fluidized bed operation and characterization of gas, tar and char yields and compositions. The results showed that the system could operate stable, and produce about 0.12 $ m^{3} $/kg gas with 22 MJ/$ m^{3} $ heating value and about 10 wt% tar when using Huainan bituminous coal under pyrolysis temperature between 500 and 600 °C. The produced gases were mainly $ H_{2} $, $ CH_{4} $, CO, $ CO_{2} $, $ C_{2} %$ H_{4} $, $ C_{2} %$ H_{6} $, $ C_{3} %$ H_{6} $ and $ C_{3} %$ H_{8} $. The CFB combustor can burn semi-coke steadily. The application prospect of the new system was discussed.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Poly-generation</subfield><subfield
