This process comprises: (a) dissolving a precursor material in a solvent to form a precursor solution and dispersing multiple nano graphene platelets into the solution to form a suspension; (b) continuously delivering and forming the suspension into a layer of solid film composed of precursor material-coated graphene platelets overlapping one another, and removing the solvent from the solid film (e.g., analogous to a paper-making, mat-making, or web-making procedure); (c) continuously converting the precursor material into nodules bonded to surfaces of graphene platelets to form a porous solid film composed of spacer-modified graphene platelets; and (d) continuously collecting the porous solid film on a collector (e.g., a winding roller).

Abstract: The present invention provides an improved process for producing diesel boiling range fuel or fuel blending component from renewable feedstocks such as plant oils and greases. The improvement involved the addition of an organic polysulfide to the renewable feedstock before it enters the pre-reaction heating unit of the process resulting in reduced fouling in the pre-reaction heating unit. The invention also provides the use of such organic polysulfide in renewable feedstocks used in hydroprocessing equipment for reducing fouling in the pre-reaction heating units of such processes.
