The invention provides a production processing technology and production equipment for naphthaline-containing hydrocarbon gas. The technology comprises the following steps: under anaerobic conditions, using raw material gas using methane as a main ingredient for a catalytic reaction to generate naphthaline-containing product gas, wherein the main ingredients of the naphthaline-containing product gas are hydrogen, a C2 component, benzene, naphthaline and part of unreacted methane; using a separating system to carry out separation and purification on the main ingredients, wherein the separating system comprises a quenching and heavy component removal unit, a compression unit and a cryogenic separation unit which are arranged in sequence, and the quenching and heavy component removal unit realizes cooling of the product gas and removal of heavy components simultaneously in virtue of liquid-phase hydrocarbon circulation absorption. The invention provides a novel chemical product production and refining production technology using natural gas/shale gas as a raw material; sufficient utilization of energy is realized in virtue of a cold box system with heat recycling and efficient heat exchange; and relatively to a traditional scheme, the flow is obviously shortened, and the investment is greatly reduced.
