摘　　要：Based on industrial production with an annual capacity of million tons of methanol,ammonia/urea,etc.,a platform technology is developed for direct,green,efficient,and high-value mega-size utilization of the CO2-rich nature gas,which is the technology of CO2-rich natural gas dry reforming and hydrogen reaction.The following technologies are discussed,such as CO2-rich natural gas dry reforming integrated with the Fischer-Tropsch synthesis to olefins(FTO)technology for producing high value-added linear alpha olefins(LAO);CO2-rich natural gas dry reforming integrated with low carbon olefin linear hydroformylation technology to produce higher carbon alcohols;direct methanol production from CO2 and hydrogen;and the new cutting edge technology of photo-catalytic process.In addition,simple techno-economic evaluations of two technologies mentioned above are discussed.The CO2-rich natural gas dry reforming integrated with FTO technology can achieve about 30%of internal rate return(IRR),while the low carbon olefin linear hydroformylation technology could have a static payback period of 2.57 years when the capacity of 2-propylhexanol(2-PH)reaches 100 kt/a.Based on the mega-size green and high-efficient CO2-rich natural gas direct utilization technology,a hybrid energy and chemical production system framework with good prospects is preliminarily designed.A modern industry zone with an annual capacity of more than 10 Mt of CO2 converted to high value-added products is underway.
