SYSTEM AND METHOD FOR HYDROGEN PRODUCTION

摘要

A system for producing hydrogen gas, carbon materials and/or carbon monoxide gas comprises a reaction chamber for chemical vapour deposition(CVD), wherein the CVD chamber includes an upwardly extending wall defining a cavity having a lower portion and an upper portion with the upper portion having a volume capacity lager than a volume capacity of the lower portion, and the wall is provided with an internal surface having a plurality of protrusions extending into the cavity for reducing horizontal cross section area of the cavity thereat.
