DESTRUCTIVE DISTILLATION OF CARBONACEOUS MATERIALS FOR PRODUCTION OF GAS, COKE, TAR, OR SIMILAR MATERIALS (cracking oils C10G; underground gasification of minerals E21B43/295)

Introduced: September 1968

Description

C10B covers the thermal decomposition of carbonaceous materials (coal, wood, oil shale, lignite, and similar substances) in the absence of air to produce coke, coal tar, coal gas, and other by-products. This class encompasses apparatus, processes, and control methods for dry distillation, including retort design, heating systems, gas recovery, and condensation of volatile products. It excludes petroleum refining and cracking processes (C10G) as well as the purification of gases already produced (C10L), focusing instead on the primary destructive distillation step itself.
