Abstract

An organic polymer can be converted to one or more lower molecular weight products by subjecting to one or more heating cycles in a porous reactor. The reactant can be provided to an inlet end of the reactor, and the products can be provided from an outlet end of the reactor. A first reactor portion at the inlet end of the reactor can have a pore size or porosity greater than that of a second reactor portion at an outlet end of the reactor. In some embodiments, the different pore sizes or porosities of the reactor portions can modulate mass transport and/or heat transfer behavior of intermediates to select for particular products at the outlet end with high yield.
