Abstract
A low-carbon production method and production system for cement clinker. The production method comprises calcining a metal oxide, which is obtained by converting carbonate in a raw material by means of a methane dry reforming reaction, to form cement clinker, and meanwhile obtaining synthesis gas. The production system uses a reformer furnace for methane dry reforming of carbonate to replace a carbonate decomposition furnace in an existing cement production system.
Claims21
A method for producing cement clinker, wherein the method comprises the following steps:
- converting carbonate in a raw material into metal oxides by means of dry reforming of methane, and then calcining the metal oxides to form cement clinker.
A production system for cement clinker, wherein the system comprises a preheater, a reformer furnace, a rotary kiln and a grate cooler arranged in sequence in a direction of material flow.
