چکیده

ed by the ether oxygen of oxanorbornene and dehydration can occur along the pathway illustrated in Figure 7.10. Figure 7.10 Proton transfer from adsorbed DMF to the cycloadduct. At the same time, proton transfer of the acidic H of the adsorbed DMF complex to p-xylene is neither energetically favorable (∆G = +27.6 kcal/mol) and has a significant energy barrier (Ea = +26.6 kcal/mol). Once the proton on the β-C of the DMF complex is abstracted, the previously adsorbed DMF molecule becomes electronically neutral, and it is likely to be displaced at the active site by the newly protonated (and positively charged) oxanorbornene. The mechanism can then proceed as proposed in the pathway

Engineering inhibitor tolerance for the production of biorenewable fuels and chemicals

Metabolic Engineering has enabled the production of biorenewable fuels and chemicals from biomass using recombinant bacteria. The economic viability of these processes is often limited by inhibition of the biocatalyst by the metabolic product, such as a carboxylic acid or alcohol, or by contaminant compounds in the biomass-derived sugars, such as acetic acid or furans. Historically, selection-b...

The Gas - Phase Conversion of Bio - Derived 5 - Methylfurfural to 2 , 5 - Dimethylfuran

* The Gas-Phase Conversion of Bio-Derived 5-Methylfurfural to 2,5-Dimethylfuran Aaron Oberg and Dennis Miller *Concern over global warming and limited oil reserves has resulted in an increased interest in the production of fuels and chemicals from biomass. Currently there is considerable interest in a class of bio-derived molecules referred to as furans. Furans contain an aromatic heterocyclic ...

Catalytic Pyrolysis of Wild Reed over a Zeolite-Based Waste Catalyst

Fast catalytic pyrolysis of wild reed was carried out at 500 ̋C. Waste fluidized catalytic cracking (FCC) catalyst disposed from a petroleum refinery process was activated through acetone-washing and calcination and used as catalyst for pyrolysis. In order to evaluate the catalytic activity of waste FCC catalyst, commercial HY zeolite catalyst with a SiO2/Al2O3 ratio of 5.1 was also used. The b...

Investigations into Apopinene as a Biorenewable Monomer for Ring- Opening Metathesis Polymerization

The ring-opening metathesis polymerization (ROMP) of apopinene is reported. We find that apopinene reacts with Rubased metathesis catalysts to provide an all trans-polymer with a polydispersity index (PDI) as low as 1.6 and molecular weights in the 1100 to 15 600 g·mol−1 range (9−127 monomer units). Because apopinene is readily prepared in one-step from myrtenal or two-steps from α-pinene, both...

Origin and Distribution of Thiophenes and Furans in Gas Discharges from Active Volcanoes and Geothermal Systems

The composition of non-methane organic volatile compounds (VOCs) determined in 139 thermal gas discharges from 18 different geothermal and volcanic systems in Italy and Latin America, consists of C(2)-C(20) species pertaining to the alkanes, alkenes, aromatics and O-, S- and N-bearing classes of compounds. Thiophenes and mono-aromatics, especially the methylated species, are strongly enriched i...
