“…Table 2 shows the different functional groups present in the distilled pyrolytic oil. (12) functional groups was identified during the analysis by the molecular vibrations inferred by the surrounding groups, and these are similar to the results obtained by Dos Santos et al [23]. These functional groups are responsible for the oil sample's chemical reactions.…”

This study investigates the performance of biodiesel produced from distilled waste tire pyrolytic oil through transesterification as a lubricant additive for aqueous drilling fluid systems. Aqueous-based drilling fluids have a high coefficient of friction as compared to oil-based drilling fluids. The inclusion of a biodiesel additive was for smooth application/operation. The friction-reducing physicochemical properties of the additive were analyzed and compared with the guidelinesof the United States specification (ASTM Standard) and the European specification (EN Standard). The chemical structure of the produced biodiesel was analyzed using gas chromatography–mass spectrometry (GC-MS). The results show that the distilled waste tire pyrolytic oil contains aliphatic, naphthenic, and aromatic hydrocarbons. The free fatty acid value reduced from 5.6% (for pyrolytic oil) to 0.64% after the transesterification process. A saponification value of 203.36 mg/g was recorded for the pyrolytic oil, and this value was also reduced to 197.35 mg/g after the transesterification process. The kinematic viscosity was reduced from 11.2 to 5.3 mm2/s for the obtained biodiesel, and this value is within the ASTM D6751 and EN 14214 standard values (1.9 to 6 and 3.5 to 5 mm2/s, respectively). The cetane number (47.75) was obtained for the biodiesel, and this is within the minimum range stipulated in ASTM D6751 guidelines. The produced biodiesel’s chemical structure analysis using GC-MS shows that it comprises of decanoic acid methyl ester and methyl ester. Furthermore, comparative analysis of the quantified friction-reducing physicochemical properties of the additive shows that the biodiesel produced from the distilled pyrolytic oil is a suitable additive for the improved lubrication of the friction-prone metallic parts of drill bits when water-based drilling fluids are employed for drilling oil and gas wells.

“…The FTS was developed in 1926 by Franz Fischer and Hans Tropsch to synthesize liquid hydrocarbons by utilizing a synthesis gas generated from coal [2]. Other suitable raw materials are natural gas as well as biogas, wood, agricultural waste, or household waste [3][4][5]. The main products of the synthesis are, depending on the process temperature, waxes in a low-temperature approach (200-240°C) and gasoline and diesel in a hightemperature approach (300-350°C) [6,7].…”

Synthesis of Light Hydrocarbons from Biogas and Hydrogen: Investigation of a Fe‐Mn‐K/MgO Catalyst

et al. 2020

synthesis of the CO 2 in biogas aims at producing light hydrocarbons and increasing its calorific value for feeding into the grid. Fe catalysts with Mn and K as promoters are supposed to yield high amounts of light hydrocarbons. Using a Fe-Mn-K/MgO catalyst, a parameter screening and long-term experiments were carried out. The catalyst shows, within the examined range, the highest selectivity to C 2-C 4 hydrocarbons at 450°C, 8 bar(a), and a gas hourly space velocity of 350 h-1. Calcination of the catalyst resulted in a significant drop of activity and an almost complete loss of selectivity to hydrocarbons. Admixture of steam to the reactant gas lowers the tendency to carbon deposition but also promotes the water-gas shift reaction and results in lower yields of hydrocarbons.

“…The Fischer–Tropsch synthesis (FTS) reaction converts syngas (a mixture of CO and H 2 ) to liquid fuels and other base chemicals using Co and Fe based catalysts 1‐3 . Syngas used for industrial FTS processes is currently derived from either natural gas or coal, but could be produced from renewable sources such as municipal waste and biomass.…”

“…It is widely accepted that the FTS reaction is a step‐wise carbon chain growth polymerization process 8 . The reactants of FTS are first converted to initiators and monomers, and the monomers then polymerize to longer chain hydrocarbon products 2,9 . Many researchers have focused on the chemical structure of the initiators and monomers and have proposed several mechanisms 9‐15 .…”

Fischer–Tropsch synthesis with ethene co‐feeding: Experimental evidence of the CO‐insertion mechanism at low temperature

et al. 2020

View full text Add to dashboard Cite

Experiments were performed at both normal and rather extreme Fischer-Tropsch Synthesis (FTS) operating conditions over a typical cobalt-based catalyst, with the aim of exploring if aspects of the reaction mechanism could be elucidated. The results show that CO reacted when co-feeding C 2 H 4 with syngas, while CO did not react with H 2 in absence of C 2 H 4 , under extremely low-temperature conditions (140 C). The adsorbed CO and C 2 H 4 may behave as monomers and initiators, respectively, and react with each other to form long chain hydrocarbons. It suggests that the C C bond coupling precedes the C O bond dissociation, which is consistent with the CO-insertion mechanism. C 3-6 product distribution with a feed of H 2 /CO/C 2 H 4 at low temperature followed the same trends in terms of normal FTS product distribution. The observed FTS-type chain growth reaction that occurs at abnormally low temperatures (140 C) when co-feeding C 2 H 4 may provide new insights into the chemistry of FTS.
