▎ 摘　　要

NOVELTY - Apparatus (10) comprises an elongate reactor having a first end and a second end, where the first end is configured to receive a hydrocarbon feedstock, a channel defined in it for conveying a fluid between the first and second ends, where the fluid is a reaction mixture comprising the hydrocarbon feedstock, a terminal section attached to the second end, where the terminal section is selectively permeable to hydrogen gas and impermeable to other components of the reaction mixture, and a hydrogen collection section (2) attached to the second end to receive hydrogen gas from the terminal section, where the hydrogen collection section is impermeable to hydrogen gas. The reactor further comprises an inlet (1) intermediate the first and second ends, where the inlet is for addition of catalytic metal particles to the reaction mixture. The reactor is made from iron. The terminal section is made from stainless steel. USE - The apparatus is used for producing graphene and hydrogen (claimed) such as methane, where the graphene is used in water purification, medicine, construction, electronic chips, and quantum computers. ADVANTAGE - The apparatus has improved methods for generating graphene and hydrogen. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for producing the graphene and hydrogen. DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional view of the apparatus for graphene and hydrogen production. 1Inlet 2Hydrogen collection section 3Continuous gas passage 4,11Outlet 6Graphene fibers 7End section 8Sleeve 10Apparatus 12Tube 15Second reaction zone 16Furnace 18,22Heating elements
