“…A mixture of gasoline and ethanol (E85 has 85% of ethanol) is commercialized in Europe and the USA. Today, most engines can operate with at least 10% ethanol blended into the gasoline (E10) [5]. Many regions around the world allow a mixture of alcohols to be blended with gasoline, in the range from methanol to octanol (boiling point lower than 210 • C).…”

“…Many regions around the world allow a mixture of alcohols to be blended with gasoline, in the range from methanol to octanol (boiling point lower than 210 • C). However, due to its toxicity, the methanol content should preferably be low [5]. Another disadvantage of ZnCu-and ZnCr-oxide catalysts is their dramatically low resistance to sulfur poisoning, which is a problem when using sulfur-containing syngas derived from coal and biomass.…”

Carbon-Supported KCoMoS2 for Alcohol Synthesis from Synthesis Gas

et al. 2021

View full text Add to dashboard Cite

KCoMoS2 was supported on various carbon support materials to study the support effect on synthesis gas conversion. Next to two activated carbons with high micropore volume, a traditional alumina (γ-Al2O3) support and its carbon coated form (CCA) were studied for comparison. Coating alumina with carbon increases the selectivity to alcohols, but the AC-supported catalysts show even higher alcohol selectivities and yields, especially at higher temperatures where the conversions over the AC-supported catalysts increase more than those over the γ-Al2O3-based catalysts. Increasing acidity leads to decreased CO conversion yield of alcohols. The two activated-carbon-supported catalysts give the highest yield of ethanol at the highest conversion studied, which seems to be due to increased KCoMoS2 stacking and possibly to the presence of micropores and low amount of mesopores.

“…Theoretically, it can be potentially synthesized directly by the reaction of the mixture of methyl nitrite and ethyl nitrite with CO. The precursor methanol, ethanol, and other lower alcohols can be synthesized by the dimethyl ether to ethanol route, − syngas to mixed alcohol route, and isopropanol–butanol–ethanol fermentation . On average, each hydroxyl group can bond to a CO molecule.…”

The mixed dialkyl oxalate (mDAO) system can be industrially synthesized inexpensively from CO with methanol, ethanol, and mixed alcohols, which are widely available from CO-rich industrial waste gases and syngas. In this work, a series of mDAOs were synthesized through solvent-free partial transesterification of dimethyl oxalate (DMO) or diethyl oxalate (DEO) with higher alcohols. The physical and chemical properties of various mDAOs and different oxygenated fuels were compared, and the viability of the mDAO as an oxygenated fuel additive was tested. The experimental data indicated that the mixed methyl ethyl oxalate (mMEO) is miscible with gasoline in any proportion at a temperature above 263 K. The mixed methyl butyl oxalate (mMBO) and mixed ethyl butyl oxalates (mEBO) show better solubility in diesel than mMEO. The research octane number (RON) of the mMEO/gasoline composite fuel increased with the increase of the mMEO concentration. The flash point, kinematic viscosity, and cetane number of the diesel mixed with a content of 10−20% mMBO meet the requirements of the China national standard. Our results indicate that mDAO can be used as a promising oxygenated fuel additive for gasoline and diesel fuels.

“…Several mesoporous structures of silicas have been used as cobalt catalyst supports in Fischer-Trospch Synthesis (FTS) [5,6]. FTS is an exothermic reaction between H 2 and CO which produce a wide variety of hydrocarbons (gas, liquid, and waxes) used as fuels and chemicals [7,8]. The porosity of the catalysts support plays an important role in this kind of reactions where bulky molecules are involved.…”

The typical MCM-41 and SBA-15 silica types were modified in order to expand their pores by addition of a swelling agent at mild conditions. The MCM-41, SBA-15 and Pore-expanded (PE) mesoporous silicas, i.e., PE-SBA-15 and PE-MCM-41 were synthesized by the atrane route and used as supports in the preparation of cobalt Fischer-Tropsch catalysts. The synthetized silicas presented a homogeneous morphology with narrow pore size distribution of 1D, 2D and 3D pore structures. The most interesting pore structure and size was presented by the PE-SBA-15 silica, which showed a 3D spherical cell structure of 30 nm diameter interconnected by small window pores of 7 nm of diameter. These supports were used in cobalt catalyst preparation. The characterization results showed that the pore structure and pore size affected the growth of cobalt oxide particles and cobalt-silica interaction. These factors played an important role on the cobalt dispersion and Degree of Reduction (DOR). Co/SBA-15 and Co/PE-SBA-15 catalysts presented similar physicochemical properties related with the Co 3 O 4 , but the pore size and structure of the support was different. All the catalysts were tested in Fischer-Tropsch reaction at close to industrial conditions. Co/PE-SBA-15 catalyst showed the best CO conversion and selectivity to long-chain hydrocarbons, results attributed to the higher degree of reduction of cobalt but mainly to the open network with 3D structure pores of the silica support which reduced the diffusion limitations of the reactants and products.
