Hydrocarbon reformer system including a pleated static mixer

A method for providing a homogenous feedstream mixture of hydrocarbon fuel and other reactants to a hydrocarbon catalytic reformer, comprising the steps of:

• a) providing a pleated static mixer having a plurality of orifices in fluid communication between first and second sides of said pleated static mixer;
• b) entering said hydrocarbon fuel into one of said first or second sides of said pleated static mixer;
• c) entering said various other reactants into the other of said first or second sides of said pleated static mixer;
• d) forcing one of said hydrocarbon fuel and said various other reactants through said plurality of orifices to cause mixing thereof with the other of said hydrocarbon fuel and said various other reactants to produce a homogenized feedstream combination;
• and
• e) providing said homogenized feedstream combination to said hydrocarbon catalytic reformer.

A static mixer for mixing a first fluid into a second fluid, comprising:

• a) a septum defining separate first and second chambers for said first fluid and said second fluid;
• b) a plurality of orifices extending through said septum in communication between said first and second chambers;
• wherein said septum defines a plurality or pleats;
• and
• wherein said plurality of pleats define a plurality of interleaved fingers;
• and
• wherein said first fluid flow through said plurality of orifices from said first chamber into said second chamber to be mixed therein with said second fluid.
