A simple procedure for chromatographic analysis of bio-oils from pyrolysis

A simple procedure was suggested for the chromatographic analyses of bio-oils from pyrolysis of various feedstock employing different technologies. An acetonitrile solution of each bio-oil was prepared without any extraction or other sample pretreatments. Preliminary thin layer chromatography showed a large number of compounds having a broad range of retention factors (Rfs) among 0-1. Products having a retention factor over 0.9 were mainly detected by GC while some other compounds were only identified by HPLC. GC/MS-FID analysis was used to identify and quantify compounds using peak areas and relative response factors (RRFs). A new equation was proposed to estimate RRFs of compounds identified via their MS spectra when experimental RRFs were not readily available. The novel procedure was employed to characterize bio-oils from pyrolysis of wood of different source or obtained using different pyrolysis procedure. Using this RRF method guaiacol, furfural, butan-2-one, levoglucosan, acetic acid and many other compounds were quantified in bio-oil samples. Different amount of them were found as a function of the type of wood, and pyrolysis conditions adopted. For instance levoglucosan was the main compound using carbon as MW absorber however acetic acid was prevalent when a MW absorber was not employed and both of them were absent in bio-oils from classical heating. The HPLC/MS of bio-oils showed cyclohexancarboxylic acid, 1,2,4-trimethoxybenzene and 2,6-dimethylphenol among the main products present in all bio-oils. On the contrary 4-hydroxyacetophenone and (3,4,5-trimethoxy) acetophenone were present in bio-oil from pyrolysis of wood using MW oven and 2,5-furandiylmethanol when a MW oven without any absorber was employed. Cyclohexanone was present in bio-oils obtained with a thermal heating or a MW oven without any absorber.

Metallocene compounds, catalysts comprising them, process for producing an olefin polymer by use of the catalysts, and olefin homo- and copolymers

Certain metallocene compounds are provided that, when used as a component in a supported polymerization catalyst under industrially relevant polymerization conditions, afford high molar mass homo polymers or copolymers like polypropylene or propylene/ethylene copolymers without the need for any alpha-branched substituent in either of the two available 2-positions of the indenyl ligands. The substituent in the 2-position of one indenyl ligand can be any radical comprising hydrogen, methyl, or any other C2-C40 hydrocarbon which is not branched in the alpha-position, and the substituent in the 2-position of the other indenyl ligand can be any C4-C40 hydrocarbon radical with the proviso that this hydrocarbon radical is branched in the beta-position. This metallocene topology affords high melting point, very high molar mass homo polypropylene and very high molar mass propylene-based copolymers. The activity/productivity levels of catalysts including the metallocenes of the present invention are exceptionally high.

Natural magnesium oxide (MgO) catalysts: A cost-effective sustainable alternative to acid zeolites for the in situ upgrading of biomass fast pyrolysis oil

The thermal and catalytic fast pyrolysis of biomass aims at the production of pyrolysis oil (bio-oil), which can be utilized as a source of chemicals or as a bio-crude for the production of hydrocarbon fuels. We investigated low-cost, naturally derived basic MgO materials as catalysts for the catalytic fast pyrolysis of lignocellulosic biomass as alternatives to classical acidic zeolite catalysts. The MgO catalysts were produced from natural magnesite mineral without any significant treatment besides calcination, crushing and sieving. Their structure, composition, porosity, morphology and surface properties were thoroughly examined by XRD, XRF, N2 porosimetry, SEM, TEM, TPD-CO2 and TPD-NH3. The physicochemical characteristics of the MgO catalysts depended mainly on the different production conditions (duration and temperature of calcination). Despite their negligible acidity, the MgO catalysts effectively reduced the oxygen content of the produced bio-oil and exhibited similar or even better performance compared to that of an industrial ZSM-5 catalyst formulation (i.e. non-catalytic pyrolysis: 38.9 wt.% organic bio-oil with 38.7 wt.% O2; ZSM-5 based catalyst: 20.7 wt.% organic bio-oil with 30.9 wt.% O2; selected natural MgO catalysts: 25.7 wt.% organic bio-oil with 31.0 wt.% O2 or 21.1 wt.% organic bio-oil with 28.4 wt.% O2). The basic sites of the MgO catalysts favored reduction of acids and deoxygenation via ketonization and aldol condensation reactions, as indicated by the product distribution and the composition of the bio-oil. Oxygen was removed mainly via the preferred pathway of CO2 formation, compared to CO and water as in the case of ZSM-5 zeolite. On the other hand, reaction coke slightly increased over the MgO catalysts as compared to ZSM-5; however, the MgO formed coke was oxidized/burnt at significantly lower temperatures compared to that of ZSM-5, thus enabling MgO regeneration by relatively mild calcination in air. A systematic correlation of product yields and oxygen content of bio-oil with the physicochemical properties of the MgO catalysts has been established.

Rhodium-catalyzed enantioselective diboration of simple alkenes

Enantioselective catalytic reactions that operate directly on inexpensive unactivated alkenes are extraordinarily useful for the preparation of chiral organic building blocks and new materials. While a number of such processes have been developed, our ability to meet the intensifying demand for inexpensive stereochemically complex materials will require a significant expansion of practical catalytic asymmetric reaction methodology. In this regard, the rhodium-catalyzed enantioselective diboration reaction has been developed in order to address a number of extant problems in catalytic alkene transformation simultaneously. This process provides an enantiomerically enriched reactive dimetalated intermediate which can be converted to a variety of difunctional reaction products. Copyright

Intermediate pyrolysis of Acacia cincinnata and Acacia holosericea species for bio-oil and biochar production

Ever-increasing energy requirements coupled with the desire to cope with global warming have motivated researchers to look for alternative energy resources. Lignocellulosic biomass is an abundant renewable energy resource which can be exploited to reduce the dependency on fossil fuel resources. Acacia cincinnata and Acacia holosericea are fast-growing tree species which produce large quantities of biomass within short span of time and does not require major agricultural inputs to grow. This study is aimed at the intermediate pyrolysis process of Acacia cincinnata and Acacia holosericea species to produce biofuels such as bio-oil, biochar and gaseous product. Mass balance was done to calculate the yields of different products along with the characterisation of bio-oil and biochar produced. Experiments were carried out in a fixed-bed reactor at the pyrolysis temperature of 500 C, heating rate of 25 C/min and nitrogen gas flowrate of 100 cm3/min for the biomass feedstock having particle size between 0.5 and 1 mm. Comprehensive thermochemical characterisation of biomass samples was carried out prior to pyrolysis experiments. The chemical composition of bio-oil samples produced was determined using Gas Chromatography-Mass Spectroscopy (GC?MS) technique. Ultimate analysis, calorific values, pH values and the ash contents in the bio-oil samples were also determined. Bio-oil produced were reported to be complex mixtures of heterocyclic and phenolic compounds resulting from the thermal degradation of basic components of biomass with the calorific values obtained in the range of 23.46?30.65 MJ/kg. Biochar samples produced in the study were characterised with the help of ultimate analysis, FTIR analysis, calorific values, pH values and SEM and EDX analysis. Properties of biochars indicated suitability for energy as well as other applications such as soil remediation and adsorption purposes. Study revealed a decent potential of Acacia cincinnata and Acacia holosericea species as biofuels resources.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Recommanded Product: 2177-47-1, you can also check out more blogs about2177-47-1
