Kinerja Katalis Paduan ZnO dengan Tembaga dan Logam-Logam Golongan VIII pada Steam Reforming Etanol menjadi Hidrogen

Kinerja Katalis Paduan ZnO dengan Tembaga dan Logam-Logam Golongan VIII pada Steam Reforming Etanol menjadi Hidrogen

Steam reforming of ethanol to H2 using ZnO catalyst with promotor metal, i.e. copper or metal group VIII (Pd, Pt and Ni) has been investigated. Catalyst’s performances are tested further at micro reactor operating at atmosphere pressure. Ethanol solution 20% is injected to reactor at rate of 2 ml/ja...
