The formation of solid carbons by LDPE pyrolysis has been studied in three different reactors: a batch feed reactor with slow heating (BFRSH), a batch feed reactor with fast heating (BFRFH), and a semicontinuous feed reactor with fast heating (SFRFH). The yield to solid carbons was low in the batch reactors with slow and fast heating (<3%) even when LDPE was copyrolyzed with polystyrene, lignin, and other additives. The yield increased to values between 15 and 52% when a semicontinuous feed reactor with fast heating was employed, which can be attributed to a longer residence time of primary pyrolysis products and higher extents of condensation reactions. Using a quartz reactor in the semicontinuous feed reaction system produced solid carbons with a homogeneous morphology of monodisperse spherules in high yields (15-43%) at temperatures of 750 and 850 °C. A Hastelloy reactor used in the same configuration produced higher yields of solid carbons (33-52%) because of wall catalysis, but the solid carbons obtained included metal alloy particles. 6 Energy & fuels 23 ARTICULO Alonso-Morales, Noelia 42429 Gilarranz, Miguel A. 42430 Heras, Francisco 42431 170858 170858 0 0 0 0 238677 BAAB BAAB 2026-03-05 200045712 0 200045712 2026-03-05 15:13:12 2026-03-05 ARTICULO
