METHOD FOR PRODUCING FUEL USING RENEWABLE METHANE
A method of producing fuel that includes providing a feed comprising natural gas, a portion of which is renewable natural gas, to a steam methane reformer in a hydrogen production unit. The feed includes a first portion that is converted to syngas and a second portion that passes through the steam methane reformer unconverted. The unconverted feed is directed to one or more burners of the steam methane reformer as fuel. The renewable natural gas is apportioned such that the first portion of the feed, which is feedstock, has a larger renewable fraction than the second portion, which is fuel. Apportioning a higher renewable fraction to the portion of the feed that is converted increases the yield of renewable content.
