... Abstract The availability of ethane and propane at a low cost from shale gas is having a great impact on the chemicals industry in the United States. Ethylene production capacity in the US is rapidly increasing with the addition of new steam crackers. Similarly, on-purpose propylene production...

... of methane to methanol, it encompassed the conversion of methane to aromatics followed by upgrading of the products by alkylation with ethane/propane. The aim of the upgrading discussed in this contribution was to avoid the toxicity of benzene as liquid fuel and to increase the research octane number (RON...

... Abstract: The propene (C 3 ~) is a main feedstock for production of many important intermediate petrochemical products. It is mainly produced by non-oxidative catalytic dehydrogenation of propane (C 3 ). The existing commercial processes are extremely complex as they operate under severe...

... such as ethane, propane, etc. The continued rise in natural gas prices is eroding this advantage. Also, the potential uncertainty in future supply of natural gas and natural gas-based feedstock, have made the location of future mega- petrochemical plants in Alberta doubtful. As a result of these concerns, some...

... we suggest a novel catalytic process for the hydroconversion of pyrolysis gasoline (from naphtha steamcrackers) or other low-value aromatic fractions into an excellent synthetic steamcracker feedstock mainly composed of ethane, propane and nbutane. It is demonstrated that this can be achieved via...

... experience in helium plant process design, construction and operation of a cascade cycle utilizing propane, ethylene, and methane as refriger- ants was selected for the Kenai project (see Fig. 1). Propane was chosen because it is available world- wide, can condense ethylene, and can be condensed by air...

Propylene-acetone is a solvent mixture, readily adaptable to propane dewaxing plants, permitting lower product pour points, lower refrigeration loads and reduced...

... analysé. La comparaison des émissions d'un même moteur alimenté successivement à l'essence et au propane met en évidence les difficultés de préparation du mélange carburé inhérentes à l'emploi de carburants liquides. Elle montre que les qualités anti-pollution des gaz liquéfiés proviennent pour...

...; present predictions are 29 billion pounds by 197019. These values are shown in Table I. In the United States the principal charge stocks are ethane and propane while outside the U.S. the usual charge stock is naphtha. In addition to ethylene, many by-products are formed. Some typical pyrolysis products...

... Abstract This is a critical analysis of the technology of processes for the conversion of petroleum fractions ranging from propane and butane to Bunker "C" fuel oils into utility gases having heating values ranging from 400 to 1,100 British thermal units per standard cubic foot (3,500...

... ABSTRACT. Oxidative cracking of propane and butane-isobutane mixtures by oxygen to yield olefines has been investigated at different temperatures, with and without catalyst and sulfur dioxide. Results are compared with those corresponding to the thermal cracking; the oxidative cracking always...

... ABSTRACT. Studies of the radiation chemistry of methane, neopentane, ethylene, ethylene-argon mixtures and ethylene-propane mixtures are discussed, insofar as possible, from the standpoint of a mechanistic description. In the case of methane the gaseous products are hydrogen, ethane, propane...

... chromatography has been employed to estimate yields of methane, propane and butane in the range of lo4 to lo-* mole per mole of ethane. Radioactive tracer techniques were used to confirm some of the findings. Methane was shown to he formed from ethane by a first order reaction with activation energy about 86...
