Latest Impact Factor figures from Elsevier's Chemical Engineering Journals
We are delighted to inform you that the recently released Impact Factor figures show, once again, a strong performance for almost all of Elsevier's Chemical Engineering journals.
The Journal of Catalysis reaches an all time high with an Impact Factor of 6.002. And whilst almost all titles show an increase in IF for the 5th consecutive year, we would like to highlight the significant increases for Advanced Powder Technology (+ 91%), Food & Bioproducts Processing (+ 60%) and Desalination (+ 39%).
As publishers of 15 of the top 20 Impact Factor titles in the field, we are indebted to the contributions of our authors, reviewers and editors.

Calculating Impact Factors
WHAT IS AN IMPACT FACTOR?
The journal impact factor is a measure of the frequency with which the average article in a journal has been cited in a particular year. The impact factor helps you evaluate a journal's relative importance, especially when you compare it to others in the same field. The impact factor is calculated by dividing the number of citations in the current year to items published in the two previous years by the total number of items published in the two previous years.
| Cites in 2011 to items published in: | 2010 2009 Sum |
= 258 = 199 = 457 |
| Number of items published in: | 2010 2009 Sum |
= 116 = 71 = 187 |
| Calculation: | Cites to recent items | 457 | = 2.444 |
| Number of recent items | 187 |
The 2011 Impact Factor for Journal X is 2.444
Journal Performance Measurements
Journal performance measurements offer a systematic, objective means to critically evaluate journals, and several indicators are available.
