Preparation, Characterization, and Activation of Co-Mo/Y Zeolite Catalyst for Coal Tar Conversion to Liquid Fuel

One of many efforts to convert coal tar into alternative liquid fuel is by hydrocracking. This research aims to determine the impregnation of Co-Mo/Y zeolite, its characteristics, the effect of impregnation temperature and time, and also the best Co-Mo/Y zeolite impregnation condition for the conversion of coal tar. This research was conducted in several steps, impregnating Co from Co(NO3)2.6H2O and Mo from (NH4)6Mo7O24.4H2O into Zeolite Y in liquid media, drying at 100 °C for 24 hours, and calcination at 550 °C for 3 hours. Coal tar was then reacted with hydrogen gas (as a reactant), and Co-Mo/Zeolite Y (as a catalyst) was conducted at 350 °C. Characteristic analysis showed that Co and Mo had impregnated into the Y zeolite, as well as it made no change of catalyst’s structure and increased the total acidity. The higher of impregnation temperature was increased the catalyst crystallinity, total acidity, and yield of gasoline. The longer impregnation time was reduced crystallinity value, but total acidity and yield were increased. GC analysis showed that products included into the gasoline product (C8, C9, and C10).

AbstractThe efficiency of metal loaded microporous materials, zeolite-Y as catalysts in the ozone initiated oxy-functionalisation of long chained n-alkanes is investigated at moderate temperature (20 ± 1 °C) and pressure conditions (1 atm.). The efficiencies of 0.5% Pd, Ni, V and U loaded microporous zeolite-Y catalysts on ozonation of higher alkanes (n-hexadecane), with respect to the conversion and transformation towards keto products are compared. In the catalysed ozonation, n-hexadecane is converted to 4-, 3- and 2- keto isomers as major products with varied selectivity and % conversions. A plausible mechanism assuming the chemisorption of the substrate molecule on the catalyst surface and further electron transfer between the metal ion loaded on the zeolite support and the active intermediate formed in course of reaction for the ozone initiated oxidation of n-hexadecane with heterogeneous Ni loaded Na-Y zeolite catalyst is proposed.

Adsorbent Dose

There are some types of crude oil that contains large quantities of various sulfur compounds that have great harm on the environment, oil economy, oil sector facilities such as fields and refineries.So developing ways to get rid of it is one of the most important goals of researchers in this sector. In this study, nanotechnology was used for environmentally friendly and available industrial materials (nano-zeolite Y), which can adsorb sulfur from crude oil, especially when it impregnated with manganese metals with ultrasound to increase the adsorption efficiency. The effect (temperature, adsorbent dose, Samples PH) was studied with ultrasound and without ultrasound.On the efficiency of removal had best results with ultrasound andit was found that this material is highly efficient in removing sulfur compounds, especially at a temperature of 100 C, and at a dose of 13 g, and PH 7 it found the best adsorption efficiency about 99 %. The change in the properties of the adsorbent material is almost non-existent, with a change in the surface area and pore size.

Atomic Adsorption Spectroscopy

Preparation of natural zeolite catalyst consist of dealumination using acid (HF 1% (v/v), HCI 1M), steaming at calcination temperature and both treatments ware carried out. The modification of the zeolite catalyst was done by loading a small amount of chromium (3% b/b) on the zeolite by ion exchange method. Ion exchange was processed by immersing the zeolite in 0.115 M chromium nitrate solution, followed by oxidation with oxygen gas and reduction by hydrogen gas. The characterization of the zeolite catalyst by mean of Si/AI ratio, acidity, metal contents (Na, K, Ca, Fe and Cr) and surface area including pore size distribution were determined by gravimetric method, ammonia adsorption, Atomic Adsorption Spectroscopy (AAS) and nitrogen gas sorption analyzer (NOVA-1000), respectively. The result of characterization showed that dealumination process increased the Si/AI ratio, acidity and decreased the metal content. The result of cracking process showed that modification of the natural zeolite catalyst enhanced the catalysis property, it showed relatively high cracking activity of petroleum fraction and low kokass formation.

Hydrogen Selectivity

Cobalt catalysts supported on Y zeolite and mesoporized Y zeolite (Y-mod) have been studied in steam reforming of ethanol (SRE). Specifically, the effect of the mesoporosity and the acidity of the y zeolite as a support has been explored. Mesoporous were generated on Y zeolite by treatment with NH4F and the acidity was neutralized by Na incorporation. Four cobalt catalysts supported on Y zeolite have been prepared, two using Y zeolite without mesoporous (Co/Y, Co/Y-Na), and two using Y zeolite with mesoporous (Co/Y-mod and Co/Y-mod-Na). All catalysts showed a high activity, with ethanol conversion values close to 100%. The main differences were found in the distribution of the reaction products. Co/Y and Co/Y-mod catalysts showed high selectivity to ethylene and low hydrogen production, which was explained by their high acidity. On the contrary, neutralization of the acid sites could explain the higher hydrogen selectivity and the lower ethylene yields exhibited by the Co/Y-Na and Co/Y-mod-Na. In addition, the physicochemical characterization of these catalysts by XRD, BET surface area, temperature-programmed reduction (TPR), and TEM allowed to connect the presence of mesoporous with the formation of metallic cobalt particles with small size, high dispersion, and with high interaction with the zeolitic support, explaining the high reforming activity exhibited by the co/y-mod-Na sample as well as its higher hydrogen selectivity. It has been also observed that the formation of coke is affected by the presence of mesoporous and acidity. Both properties seem to have an opposite effect on the reforming catalyst, decreasing and increasing the coke deposition, respectively.
