▎ 摘　　要

NOVELTY - Process for producing hydrogen in hydrocarbon fields using microwave directional guide antennas moved by downhole tractors along horizontal or inclined sections of the wellbore used to generate hydrogen by microwave heating, plasma pyrolysis and catalytic cracking of gas drained into the well through an artificially created system of fractures filled with catalyst particles together with proppant, where the process uses mobile or surface stationary electromagnetic wave generators, well transmission lines and bottom-hole waveguide antennas, or microwave generation tubes installed downhole, hydraulic multistage reservoir fracturing technics to establish a system of propped fractures around the wellbore. The advanced carbon products like graphene and activated carbon resulting from plasma hydrocarbon pyrolysis process can be produced to the surface at low cost. USE - The process is used for producing hydrogen in hydrocarbon fields, and for producing advanced carbon products like graphene and activated carbon. ADVANTAGE - The process produces advanced carbon products like graphene and activated carbon resulting from plasma hydrocarbon pyrolysis process at low cost.
