Abstract:

Hydrogen­free, ambient­pressure decarboxylation over activated carbon, also called Gas­phase heterogeneous Catalytic Cracking (GCC), produces fuel­blending hydrocarbon liquids from bio­based waste oils and fats. In bench­scale, up to 80 % energetic yield of liquid product was achieved. Coke formation and blocking of pores lead to a demand of 0.15 g of activated carbon per g feedstock. Re­activation by targeted gasification reactions inside the pores turned out to be suitable for reestablishing the pore system and regaining a ‘catalyst’ suitable for the decarboxylation process. Nine cycles of catalyst usage and re­activation were performed without any negative implications on catalyst performance.
