A preparation process of polyimide aerogels that composed of aromatic dianhydrides and aromatic diamines or a combined aromatic and aliphatic diamines is described. Also descried is a process to produce carbon aerogels derived from polyimide aerogel composed of a rigid aromatic diamine and an aromatic dianhydride. Finally, the processes to produce carbon aerogels or xerogel-aerogel hybrid, both of which impregnated with highly dispersed transition metal clusters, and metal carbide aerogels, deriving from the polyimide aerogels composed of a rigid aromatic diamine and an aromatic dianhydride, are described. The polyimide aerogels and the polyimide aerogel derivatives consist of interconnecting mesopores with average pore size at 10 to 30 nm and a mono-dispersed pore size distribution. The gel density could be as low as 0. 008 g/cc and accessible surface area as high as 1300 m/g.

Sulfur is removed from a hydrocarbon fuel via contact with a desulfurization agent; the desulfurization agent is then regenerated (wherein sulfur is released) by exposing it to oxygen. The sulfur removal and regeneration processes each can be carried out at relatively moderate temperatures, e. g. , from 300 to 600 C. , and pressure, e. g. , about 0. 79 to about 3. 5 MPa; and the desulfurization agent can include a transition metal oxide, such as molybdenum oxide. The process can also include the additional steps of cracking the hydrocarbon, separating high-boiling and low-boiling fractions from the reaction product and contacting the lower-boiling fraction with a secondary desulfurization agent.

An apparatus for processing hydrocarbon fuel (e. g. , gasoline, kerosene, jet fuel, diesel and heating oil) to generate hydrogen (H), which can be used in fuel cells, includes a desulfurization reactor for removing sulfur from the fuel; a catalytic reactor for forming a reformate from the fuel; and, optionally, a separator for separating a light fraction of the fuel from a heavy fraction of the fuel. The fuel is first exposed to the desulfurization reactor and then, if present, to the separator. Finally, the fuel is exposed to the catalyst in the catalytic reactor; and the hydrogen gas generated there from is collected for use in the fuel cell.
