Conversion of natural gas to liquids via acetylene as an intermediate

摘要: This paper describes an experimental investigation of the conversion natural gas to liquid transportation fuels through acetylene as intermediate. The first step is direct thermal methane utilizing a plasma heat source dissociate methane. dissociation products react form mixture and hydrogen. Significant improvements over prior art were observed; these may be attributed improved injection configuration minimization radial temperature gradients. Conversion efficiencies (percent converted) approached 100% yields in 90–95% range with 2–4% solid carbon production obtained. A variety methods examined for second step, products. most promising technology was reaction hydrogen shape-selective zeolite C3–C5+ aliphatics.
