Answer: Thank you for the comments. On the home page of Fuel Processing Technology, the aims and scope are described as following. “Fuel Processing Technology (FPT) deals with the scientific and technological aspects of converting fossil and renewable resources to clean fuels, value-added chemicals, fuel-related advanced carbon materials and by-products.” In fact, carbon dioxide (CO2) is not only a greenhouse gas but also the most abundant C1 resource on the earth. The conversion of CO2 into styrene carbonate fits the topics of “converting renewable resources to value-added chemicals”. So we think our work fits in 'aims and scope' of the journal well. Comment 1: The abstract is too brief. Please add a short introductive sentence. Answer: A short introductive sentence has been added in the revised manuscript. Comment 2: Introduction section must be developed. Please focus the state of the art on your subject. The paper is descriptive. The scientific approach (phenomenon description and explanations must be improved.) Answer: Thanks for the comments. We did our best to revise and improve the introduction as well as the description about t. All the changes have been marked in blue color in the present version. Comment 3: Please avoid formulation such as: "the catalyst can be reused three times" This is not engineering formulation. Answer: "the catalyst can be reused three times" in the highlights has been revised. Comment 5: Add variation curves of the catalysis efficiency as well as the calculation method. Answer: We are sorry that we possibly didn’t grasp the comment “Add variation curves of the catalysis efficiency” truly. So we answered it based on our understanding. Both tables and figures are generally employed to describe results, they can be used together or not [1-3]. However, tables are widely employed once the evaluated parameters above 2 [4,5]. We think it’s suitable to describe the catalysis efficiency by table in the present work since the conversion of styrene oxide, the selectivity and yield towards styrene carbonate were given and discussed in detail. The calculation equations for the conversion of styrene oxide, the yield and the selectivity to styrene carbonate have been supplied. Please see the section of “Determination of conversion, yield and selectivity” in the revised version. Comment 5: Minor grammatical issues need to addressed. Answer: Thank you for the comments. We did our best to check the whole manuscript and all the revisions were marked in blue color.
