Pemurnian Hidrogen Pada Proses Steam Methane Reforming Menggunakan Metode Pressure Swing Adsorption Pada Waktu Adsorpsi 120 Detik

Abstract

Hydrogen is utilized as a fuel because it has advantages over conventional fuels, which producing high energy without causing
pollution. One of the technologies used to produce hydrogen is steam methane reforming (SMR), in which methane is reacted
with steam, typically using a catalyst, to make a mixture of carbon monoxide and hydrogen. The product of the SMR process
is syngas, which is then fed into a Water Gas Shift (WGS) reactor, where the carbon monoxide (CO) content in the syngas is
converted into carbon dioxide (CO₂) to produce hydrogen. The composition resulting from the WGS process then enters the
next stage, which pressure swing adsorption (PSA). This process is carried out to obtain hydrogen with a higher level of purity.
PSA has several parameters, including the number of beds, operating pressure, type of adsorbent, and the adsorption time
used. This study was conducted to determine hydrogen purity with an adsorption time of 120 seconds in PSA using silica gel
and activated alumina as adsorbents. The results showed an increase in hydrogen purity from 49% in the WGS stage to 67%
after purification using the PSA method.
