Sustainability assessment of polygeneration processes based on syngas derived from coal and natural gas

Combining coal gasification, natural gas reforming, and external carbonless heat for efficient production of gasoline and diesel with CO2 capture and sequestration

“…Li et al [28] examined a similar system using a combined biomass-natural gas feedstock to get 9% fuel input saving compared with individual systems which use either biomass or natural gas as resource for methanol/power production. Gangadharan et al [30] compared two different DME/power polygeneration systems, using coal and natural gas in a variety of configurations. It was found that natural gas as co-feed to coal can improve both the thermal efficiency and the CO 2 emissions rate.…”

A new power, methanol, and DME polygeneration process using integrated chemical looping systems

“…Coal is still a relatively inexpensive and reliable resource for most industrialized countries (50% of electricity in the United States comes from coal [1]). Most research in this area focuses on advanced concepts such as: (1) decreasing the carbon capture cost by switching from traditional pulverized coal combustion plants to the integrated gasification combined cycle process (IGCC) as an approach to replace the low-concentration CO 2 absorption processes with more effective techniques [2]; (2) improving the efficiency and flexibility of power plants by using multi-product processes [3]; and (3) integrating existing techniques with alternative energy sources such as natural gas [4][5][6] and biomass [7].…”

Prioritization of bioethanol production pathways in China based on life cycle sustainability assessment and multicriteria decision-making

“…The multiple indicators type means that multidimensional criteria are used for sustainability assessment. For instance, Gangadharan et al (2012) used a total of eight criteria (three related to economic aspects, three related to environmental aspects, and two related to social aspects) for the sustainability assessment of the polygeneration process based on syngas derived from coal and natural gas. Piluso et al (2010) used a total of 11 criteria (four related to economic aspects, four related to environmental aspects, and three related to social aspects) for the sustainability assessment of an industrial system.…”
