To calculate the potential aromatic content in the reprocessed raw materials, only the percentage levels of naphthenes and aromatics are needed. Answer: A. Promotion of petrochemical activities: ☛Notice on the launch of the large-scale event “I’m saving energy; where are you?” in the petrochemical area: http://bbs.hcbbs.com/thread-1579199-1-1.html (Source: Haichuan Chemical Industry Forum). This event offers awards in both textual and photographic categories. When there are over 200 entries, an additional grand prize will be awarded, worth 600 Haichuan coins; if there are more than 300 entries, the grand prize value increases to 1,000 Haichuan coins, and if there are 500 entries, it rises to 1,500 Haichuan coins. First prize: 3 Haichuan commemorative water cups. Second prize: 5 winners, each receiving 120 Haichuan coins. Honorable mentions: several winners, each receiving 200 wealth points. --------------------------------------------------------------------------------------------------------- ☛“My Plant, My Home” – Photo competition (10 wealth points per photo): http://bbs.hcbbs.com/thread-1495069-1-1.html (Source: Haichuan Chemical Industry Forum). --------------------------------------------------------------- ☛Haichuan Freelancers’ large-scale “public welfare” event is now underway! http://bbs.hcbbs.com/thread-1576975-1-1.html (Source: Haichuan Chemical Industry Forum) Looking forward to your participation
To calculate the potential aromatic content of the reformed feedstock, only the percentage contents of naphthenes and aromatics are required. (True)
To calculate the potential aromatic content of the reformed feedstock, only the percentage contents of naphthenes and aromatics (X) are required
Potential aromatic content % (by mass) = ∑ + ∑Ai, where Mni is the molecular weight of cycloalkane i, Ni is the mass percentage of cycloalkane i, and Ai is the mass percentage of aromatic compound i. Potential aromatic content = N + 2A; N represents the content of cycloalkanes, while A represents the content of aromatics. http://www.chemask.com/browse_question.asp?ask_id=2141
