Biocatalytic propane production: structure-based engineering of aldehyde-deformylating oxygenase improves specificity for short- and medium-chain-length aldehydes and enhances the propane generation in whole-cell biotransformations. This presents new opportunities for developing biocatalytic modules for the production of volatile "drop-in" biofuels.

For the first time laser-induced gratings (LIGs) have been used for the investigation of a non-stationary pulse-repetitive injection process of gaseous propane, C(3)H(8), into air. By recording and evaluating single-shot LIG signals it was possible to determine, on a cycle-averaged basis, the temporal evolution of the local (within a probe volume 300 microm in diameter and 10 mm in length) equi...

In the title compound, C(13)H(28)N(2) (2+)·SO(4) (2-)·H(2)O, extensive hydrogen-bonding inter-actions between the protonated 4,4'-(propane-1,3-di-yl)dipiperidinium ions, the sulfate anions and the water mol-ecules lead to a three-dimensional pillared and layered structure with the 4,4'-(propane-1,3-di-yl)-dipiperidinium ions acting as the pillars.

We used dispersion-corrected density functional theory (DFT-D3) calculations to investigate the initial C-H bond cleavage of propane σ-complexes adsorbed on the PdO(101) surface. The calculations predict that propane molecules adsorbed in η(1) configurations can undergo facile C-H bond cleavage on PdO(101), where the energy barrier for C-H bond activation is lower than that for desorption for e...

Exceptional high quality ZIF-8 membranes prepared through a novel seeded growth method in aqueous solutions at near room temperature exhibit excellent separation performance for C2/C3 hydrocarbon mixtures. The separation factors for mixtures of ethane/propane, ethylene/propylene and ethylene/propane are ∼80, ∼10 and ∼167, respectively.

This study developed single-well, gas-sparging tests for assessing the feasibility of in situ aerobic cometabolism of trichloroethene (TCE) and cis-1,2-dichloroethene (cis-DCE) using propane and methane as growth substrates. Tests were performed in groundwater contaminated with TCE (100-400 microg l(-1)) and cis-DCE (20-60 microg l(-1)). A series of gas-sparging tests was performed by first spa...

solubility of hydrocarbons in water is important due to ecological concerns and new restrictions on the existence of organic pollutants in water streams. also, the creation of a thermodynamic model has required an advanced study of the phase equilibrium between water (as a basis for the widest spread muds and amines) and gas hydrocarbon phases in wide temperature and pressure ranges. therefore,...

Propylene is an important raw material and extensively used in the petrochemical industry. There has been a continuously growing demand for propylene in recent years around the world1–3. The majority of propylene is produced as a byproduct from processes such as steam cracking of naphtha and fluid catalytic cracking (FCC)4,5. Additional sources of propylene included dehydrogenation of propane, ...

Infrared (IR) spectra of the hydrocarbon ices C3H8 (propane), C3H6 (propylene, propene), and C3H4 (propyne, methylacetylene) are relevant to study low-temperature chemistry spectroscopy objects within beyond Solar System, but IR band strengths absorption coefficients lacking for these compounds. Here we present new crystalline non-crystalline forms C3H8, C3H6, C3H4. Measurements ice density ref...
