Abstract Scope |
Additively manufactured (AM) reactors were built by direct laser metal sintering for steam methane reforming using Haynes 282 feedstock. Cost modeling of the reactor using AM over subtractive manufacturing resulted in a 58% savings at a 100units/yr production rate. Small test articles were made to evaluate the material data at extreme temperatures by thermal cycling from 300℃ to 850℃ and after 4000 cycles no deformation or rupture was observed. Therefore, it is expected that a full scale reactor lifetime is > 10 years. The full-scale reactor was heated to ≥ 750℃ and fed with steam and methane to produce a product syngas stream containing predominantly hydrogen with a hydrogen production rate of > 9 kg/day. A custom 5kW, 208V induction system was used to heat the reactor to reforming temperatures. Over 82% efficiency of electrical power to chemical energy was achieved, which is a world record for thermochemical conversion. |
