A C1 to C4 monohaloalkane is converted to hydrocarbons having a greater number of carbon atoms than the monohaloalkane reactant, in particular to aliphatic hydrocarbons in the gasoline boiling range, by contacting the monohaloalkane at elevated temperature with a clay containing either hydrogen ...
It was, however, felt that the use of such columns for low-boiling hydrocarbons (below C) is possible only at `very low' temperatures. According to our best knowledge, the separation of methane, ethane and ethylene with open tubular columns was not yet reported....
1c). In pure water the activity was nil, whereas in 1 mol% EMIM-BF4 solution the generation of C1, C2, and C3 hydrocarbons was observed. The CO2RR activity, as quantified by turnover frequencies (TOFs) of the hydrocarbon products, increased dramatically with an increase in the EMIM-...

In addition, the resulting gas mixture containing C1–C4 hydrocarbons needs additional separation process so as to obtain high-purity olefins such as C2= and C3=. Thus, the development of low-energy and highly selective CO conversion process for light-olefin synthesis is still required. ECOTE ...
C1-C5 hydrocarbons from DSDP Legs 56 and 57 sediment gas pockets were analyzed on board ship. Results suggest that the C2-C5 hydrocarbons accompanied biogenic methane and were generated at low temperatures — less than 50° C — either by microorganism s or by low-temperatu re chemical reaction...
1. In a process for conversion of hydrogen and carbon monoxide into C1-C4range hydrocarbons; which comprises: Forming an ebullient bed of particulate conversion catalyst in a reaction zone, with a feed gas comprising hydrogen and carbon monoxide in a molar ratio in the range of at least 1:1...
Disclosed herein is a process for the preparation of dimethylether from hydrocarbons, including tri-reforming a feedstock mixture comprised of hydrocarbons, carbon dioxide and water vapor in the presence of a tri-reforming catalyst, to prepare a syngas, which then undergoes gas-phase direct synthesis...

Both these polymers are stable to lower hydrocarbons and can be used for hydrocarbon-containing gas mixture separation. It is known that PMPentene is characterized in terms of C1–C4 permeability as a conventional glassy polymer (C1 > C2 > C3 > C4) [13]. In contrast, PMPentyne shows the...
