Abstract

Reaksi hidrolisis antara logam-air adalah salah satu cara paling menjanjikan untuk menghasilkan hidrogen yang bersih dan ekonomis. Pada tugas akhir ini akan meninjau ketebalan limbah aluminium dengan memvariasikan konsentrasi promoter NaOH. Selain itu, akan dilihat Al(OH)3 yang terbentuk setelah terjadinya reaksi maupun secara model kinetika. Aluminium yang digunakan adalah aluminium limbah AA1235 dari PT Supra Aluminium Industri sebanyak 0.1 gram dengan ketebalan 6.5, 11,5 dan 19,5 m dengan variasi promoter NaOH 0.3 , 0.4 , dan 0.5 . Aluminium dengan ketebalan lebih tipis dan Penambahan katalis NaOH dapat mempercepat laju reaksi. aluminium dengan ketebalan yang lebih tipis lebih cepat bereaksi dan lebih mudah untuk dipengaruhi oleh faktor eksternal seperti dislokasi dan penambahan katalis NaOH dan NaAlO2. Penambahan NaOH dapat meningkatkan pH sehingga meningkatkan yield produksi hidrogen. Reaksi yang lebih cepat dapat dimodelkan dengan permodelan shrinking core sedangkan reaksi yang lebih lambat lebih cocok dimodelkan menggunakan model penurunan massa. Al(OH)3 yang terbentuk secara umum terlalu sedikit untuk dideteksi secata kuantitatif dikarenakan jumlah sampel yang terlalu sedikit.

The metal-water hydrolysis reaction is one of the most promising ways to produce clean and economical hydrogen. This final project will review the thickness of aluminum waste by varying the concentration of the NaOH promoter. In addition, Al(OH)3 formed after the reaction will be analyzed as well as kinetic models. The aluminum used was AA1235 waste from PT Supra Aluminum Industri. Each experiment was undertaken under the same aluminium mass of 0.1 gram taken from foil with thicknesses of 6.5, 11.5 and 19.5 μm and was further exposed to aqueous solution containing NaOH promoter with molarities of 0.3, 0.4, and 0.5 M and 0.01M NaAlO2. All processes were carried out at room temperature. Hydrogen production was measured by means of open manometer method and MQ-8 sensor. The pH before and after reactions were recorded. The 6.5 μm aluminum foil having the largest dislocation density show an accelerated reaction rate of 5.9981 ml/minutes, 10.0796 ml/minutes, and 11.162 ml/minutes with NaOH promoter molarities of 0.3, 0.4, and 0.5 M, respectively, where the kinetics can be approximated through shrinking core model. The aqueous solution pH remains in the range of 13, which is beneficial for hydrogen production. The amount of Al(OH)3 as thermodynamically stable reaction product was too few to be identified using XRD. However from SEM-EDX characterization Al(OH)3 was present in the form of small particulates on top of perforated aluminum surface
