(2013) determined the temperature ranges of pyrolysis and obtained the pyrolysis products of three working fluids (isobutane, isopentane and HFC-245fa) by experiment. A rapid experimental method for assessing the thermal stability of ORC working fluid was presented, and the pyrolysis temperatures of ...
CC(C)C represents isobutane. As a first example of the application of operators, let us begin with the expression of cyclohexane just mentioned, which we use now as a seed, or starting string, named ω: ω = C1CCCCC1 Trivially, if this string is used as input in a molecular drawing...
For this reason, in many cases the unit for the molecular weight is not mentioned; however, one must realize that it is not a dimensionless parameter. The molecular weight of a pure compound is determined from its chemical formula and the atomic weights of its elements. The atomic weights ...
Liquid-Phase Isobutane/Butene-Alkylation Using Promoted Lewis-Acidic IL-Catalysts The effect of different promoters on activity and selectivity of Lewis-acidic chloroaluminate ionic liquid catalysts was studied for isobutane/2-butene alk...

The instant catalytic cracking catalysts are useful for cracking a hydrocarbon feedstock to produce lower boiling hydrocarbons. The catalysts comprise an effective amount of at least one non-zeolitic molecular sieve characterized in its calcined form by an adsorption of isobutane of at least 2 percent...

The SAPO-34 structure is characterized in that it adsorbs xenon but does not adsorb isobutane, indicating that it has a pore opening of about 4.2 angstroms. SAPO-34 is a silica-aluminophosphate material with the chabazite (CHA) framework structure. The structure is rhombohedral and can be ...
