“…The non-closure of pores by nanoparticles also results in more optimal pyridine adsorption so that the acidity increases. According to Nugrahaningtya et al [26], the presence of an increasing amount of metal loading makes the pores in the carrier material unable to adsorb due to steric resistance. In addition, an increase in Ni metal can cover the catalyst cavity, causing the Lewis acid site to be closed due to agglomeration.…”

In the present work, optimum conditions for hydrocracking of waste palm cooking oil (WPCO) over a Ni-NH2/Lapindo mud catalyst were studied to obtain a high quantity and quality of biofuel. The utilized catalyst support material was Lapindo mud (LM) from Sidoarjo, Indonesia, which was only given physical treatment (i.e., washing, drying, grinding, and calcining). Ni/LM was prepared via wet impregnation in three different Ni weight loadings: 1, 5, and 10 wt.%, which were denoted as Ni(A)/LM, Ni(B)/LM, and Ni(C)/LM, respectively. As a result, the hydrocracking test of WPCO under the temperature of 470 °C and a feed/catalyst weight ratio of 50 showed that the Ni(A)/LM catalyst produced the highest liquid product reaching 46.65 wt.% among the other Ni-based catalysts. The liquid product can be increased drastically to 63.93 wt.% under a more optimum temperature at 550 °C. Functionalization of Ni(A)/LM as the best catalyst was carried out by grafting method with NH2 groups from 3-APTMS, resulting in Ni(A)-NH2/LM. This modification increased the liquid product to 68.17 wt.% under hydrocracking conditions using a weight ratio of 75. Moreover, the reusability of Ni(A)-NH2/LM was found to be effective for three hydrocracking runs, constantly yielding an average biofuel of 80 wt.%.

“…Pengemban USY memiliki aktivitas katalitik lebih baik dibandingkan dengan Al 2 O 3 dalam desulfurisasi tiofen (Rawat et al, 2010). Logam Co dan USY berperan dalam hidrogenasi dan dehidrogenasi (Nugrahaningtyas et al, 2009;Wang and Iglesia, 2010), sedangkan logam Mo yang berperan dalam proses penghilangan sulfur (Liu et al, 2015). Oleh karena itu, paduan logam CoMo/USY mampu memiliki aktivitas katalitik yang tinggi.…”

Telah dilakukan uji aktivitas katalis CoMo/USY pada reaksi desulfurisasi tiofen. Reaksi dilakukan pada reaktor sistem batch dengan tekanan gas N2 sebesar 1 bar gas N2 dan waktu reaksi selama 1 jam. Penelitian ini bertujuan untuk mengetahui pengaruh variasi temperatur dan variasi karakter katalis pada reaksi desulfurisasi tiofen. Product desulfurisasi dianalisis dengan GC-MS. Karakter kestabilan struktur katalis dilihat dengan analisis menggunakan instrument FT-IR. Hasil analisis terhadap uji aktivitas desulfurisasi menunjukkan bahwa pada rentang temperatur 200-300°C, rendemen bertambah dengan meningkatnya temperatur. Adapun efek karakter katalis terhadap aktivitas katalitiknya menunjukkan bahwa karakter katalis yang paling dominan adalah sifat keasaman. Katalis dengan keasaman tertinggi, yaitu katalis CoMo/USY, memiliki aktivitas tertinggi dalam desulfurisasi tiofen dengan rendemen produk sebesar 2,88%. Hasil analisis FT-IR terhadap katalis bekas menunjukkan bahwa struktur cukup stabil dan tidak ada pengotor yang terikat pada katalis.Catalytic Desulfurization of Thiophene using Como/Usy Catalyst in Batch Reactor. CoMo/USY catalyst activity has been tested for thiophene desulfurization reaction. The reaction was carried out in batch system reactor with N2 gas pressure of 1 bar and reaction time for 1 hour. This study aims to determine the effect of temperature variation and catalyst character variation in thiophene desulfurization reaction. The desulfurization products were analyzed by Gas Chromatography - Mass Spectra (GC-MS). The characters of structure catalyst were analyzed by Fourier Transform Infrared Spectroscopy (FT-IR). The results of the analysis of the desulfurization activity test showed that in the temperature range 200-300 °C, the yield raised with increasing temperature The analysis results of the desulfurization activity test showed that in the temperature range of 200-300°C, the yield raised with increasing temperature. The effect of the catalysts character on its catalytic activity shows that the most dominant character of the catalysts were its acidity. The highest acidity catalyst, CoMo/USY catalyst, has highest activity in thiophene thiophene with the product yield of 2,88%. The result of the FTIR analysis on used catalyst show that the structure was stable and no impurities were attached the catalyst.

Hydrocracking of cashew-nut shell liquid (CNSL) into energy-affording fractions has been investigated using catalyst of acid-acticated natural zeolite (ZAA), to which were further impregnated unimetal (NiO) and bimetal (NiOMoO) elements, thereby comprising two catalyst types (NiO/ZAA and NiOMoO/ZAA). This research aimed to examine how potential was the conversion of CNSL into energy-affording fractions, and to look into such metal imregnaton into ZAA catalyst on the performance of hydrocracking reaction. Catalyst characterization included determinig consecutively acidity using ammonia-base adsorption, and crystalinity using X-ray diffraction (XRD). Acid activation and metal impregnation increased the catalyst acidity and its crystalinity. The hydrocracking was carried out in a fixed-bed reactor employing the temperature 450 C, the CNSL feed/catalyst ratio of 6, and flow rate of H at 20 ml/minute. The hydrocracking converted the CNSL into products that comprised the liquid-phase, gas-phase, and solid-phase (cokes) fractions,, which in all afforded energy, and the conversion of each fraction was examined. The liquid-phase product was further analyzed using gas chromatography (GC), which revealed that the GC's eluted liquid fraction were predominantly gasoline, diesel oil, and heavy oil. Each eluted fraction was further examined for its selectivity based on the elucidated GC area for each fraction over the total GC area for the overall liquid fractions. The hydrocracking performed optimally using NiOMoO/ZAA catalysts. Which converted as much 75.42% (the greatest) of the CNSL as the liquid product, with also the greatest in selectivity towards gasoline and diesel-oil fraction at 38.45% and 19.87%, respectively. The impregnation of metal element, particularly bimetal (NiOMoO) into ZAA catalyst indicatively enhanced the hydrocracking performance.
