oil and how it bcomes fuel

I have learned several new ideas and facts from this class. From why I should not be smoking, to what is in our drinking water, to things I can do to reduce my carbon footprint. The concept I found to be most interesting was the process by which we refine crude oil into all the finished products, such as gasoline. I knew the gasoline we put in our cars was not the stuff that came out of the ground, but I was pretty clueless about the process. Also the amount of different products that result from burning off at different temperatures was interesting as well.
Upon further investigating the wild and wonderful world of oil refineries I found and interesting aspect of the process to be the coking and cracking aspect.Cracking is essentially the breaking down of hydrogen molecules into lighter molecules at extremely high temperatures (600 degrees Cecilius). A cocker is used to heat and compress the crude oil into a hard coal like substance used for industrial fuel. I wonder if there is anyway to store hydrogen in a form like this? There is another form of molecular conversion known as alkylation. This process takes gas byproduct from cracking and combines them, essentially cracking in reverse. These three processes are part of the larger process at the refinery known as conversion.
