No big deal, but .... 

Regarding your very recent relocation of some equations in the Hydrodesulfurization article. As the primary author of that new article, I deliberately had the two equations further to the left of the page because I believe it looks better that way. Do you feel very strongly that they should be centered as you did?  If not, I would like to revert your change. Please let me know here on your Talk page.  Regards, -
