Steam reforming of naphtha is a source of hydrogen production for nitrogenous fertiliser industry. What is the usual ratio of steam to carbon maintained in the process of steam reforming of naphtha ?
Correct answer: A. 3.5 : 1
- A. 3.5 : 1
- B. 1.5 : 1
- C. 10 : 1
- D. 15 : 1
Explanation
A steam-to-carbon ratio of about 3.5:1 is commonly maintained in naphtha reforming to provide sufficient steam for conversion and to limit carbon deposition on the catalyst. Ratios such as 10:1 or 15:1 would impose unnecessary energy and equipment loads.
