The title compound, C(9)H(12)N(2)OS, was obtained unexpectedly in a multicomponent reaction of an equimolar ratio of phenyl isothio-cyanate, malononitrile and amino-ethanol. The -C(H(2))-N(H)-(C=S)-N(H)- methyl-thio-urea-methane group is almost normal to the phenyl ring, with a dihedral angle of 71.13 (9)°. The N-C-C-O torsion angle is 72.8 (2)°. In the crystal, mol-ecules are connected by N-H⋯...

1L spraying reactor with a heat exchanger outside was used to investigate the effect of spraying hydration process on storage capacity of methane in hydrate and on a methane storage rate in hydrate to solve a problem of lower gas molecular transfer rate and worse heat transfer rate. Some results showed that ethanol as a promoter had better spraying hydration rate under the liquid spraying press...

Lignocellulose—a major component of biomass available on earth is a renewable and abundantly available with great potential for bioconversion to value-added bio-products. The review aims at physio-chemical features of lignocellulosic biomass and composition of different lignocellulosic materials. This work is an overview about the conversion of lignocellulosic biomass into bio-energy products s...

results the modeling results showed that for the gas recovery starting in 2000 and 2015, the power generation would be 2,354 and 830 mw, respectively. in fact, the 15-year difference in gas extraction made a 200% difference. based on the results, from 2000 to 2100, 558 m3/hour of methane would be extracted, which would be equivalent to 2,354 mw energy. subsequently, the emission of 93,721,837 t...

This chapter reviews recent studies of catalytic reforming of logistic fuels at hightemperature. Aside from steam and autothermal reforming, special consideration is given to partial oxidation conditions. Natural gas, gasoline, diesel, and ethanol containing fuels are discussed. Methane and iso-octane as fuel surrogates are exemplarily used to explain the behavior of the reformers in particular...

METHODS: Nineteen vials of tetrofosmin were radiolabelled with Tc and the percentages of the RCP were determined. Five different methods were compared with the standard RCP testing method (ITLC-SG, 2x20 cm): Whatman 3MM (1x10 cm) with acetone and dichloromethane (method 1); Whatman 3MM (1x10 cm) with ethyl acetate (method 2); aluminum oxide-coated plastic thin-layer chromatography (TLC) plate (...

In a recent paper [M. D'Alessandro, M. D'Abramo, G. Brancato, A. Di Nola, and A. Amadei, J. Phys. Chem. B 106, 11843 (2002)] we showed how to combine molecular dynamics simulations with the quasi-Gaussian entropy theory, in order to model the statistical mechanics and thermodynamics of ionic (water) solutions. In this paper we extend the method to treat nonspherical solutes, describe more thoro...

Introduction: Methane is one of the most widely used gases in industries with a high flammability potential. This study aimed to evaluate the efficiency of ventilation systems installed on methane valve pits based on hazardous areas classification. Material and Methods: This study was implemented in a steel industry in Qom Province in 2019. The tools used in this study were a DELTA OHM pitot t...

A nonmotile, gram-positive, spherical organism was isolated from the intestinal tracts of rabbits. Both hydrogen and methanol were required for growth. No methane was produced from hydrogen-carbon dioxide, formate, acetate, methylamines, ethanol, or isopropanol. The optimum pH was 6.8, and the optimum temperature was 35 to 40 degrees C. The DNA G+C content is 23 mol%. The pseudomurein cell wall...

coalbed methane (cbm) plays an important role in coal mining safety and natural gas production. in this work, the cbm potential of b2 seam in parvadeh iv coal deposit, in central iran, was evaluated using a combination of local regression and geostatistical methods. as there were 30 sparse methane sampling points in the parvadeh iv coal deposit, no valid variogram was achieved for the methane c...
