A system for continuously producing biocoke, wherein the system comprises a kinetic interface reactor, wherein the kinetic interface reactor comprises a first inlet configured for feeding a heated biogas stream and/or a bioliquid stream into the kinetic interface reactor, wherein the heated biogas stream comprises a carbon-containing vapor, and wherein the bioliquid stream comprises a carbon-containing liquid, wherein the kinetic interface reactor is configured to operate under effective reaction conditions to convert the carbon-containing vapor and/or the carbon-containing liquid to solid biocoke, wherein the kinetic interface reactor comprises a first outlet configured for continuously or semi-continuously withdrawing the solid biocoke, wherein the kinetic interface reactor comprises a second inlet configured for feeding at least some of the solid biocoke that was withdrawn from the outlet, and wherein the first outlet, or a second outlet, is configured for withdrawing and recovering a biocoke product.
