  • terminology - Is reforming and isomerization the same thing . . .
    Reforming is a processing technique by which the molecular structure of a hydrocarbon is rearranged to alter its properties The process is frequently applied to low-quality gasoline stocks to improve their octane number and thereby improving combustion
  • Can carbon dioxide be reduced to carbon monoxide and oxygen to produce . . .
    There are lots of questions about reducing or burning CO 2 to carbon and oxygen to solve climate change, but of course that wouldn't work because it takes a lot of energy But carbon monoxide is more stable than the dioxide, so could CO2 be split into CO and oxygen to create more heat? Of course this is a bad idea since it'd produce a toxic gas but is it at least theoretically possible
  • What happens to the waste products from crude oil refining?
    The process of refining of crude oil is used to separate crude into fractions of various derived products For example, crude contains fractions of gasses such as methane, ethane, propane, butane,
  • Why do highly branched alkanes have higher octane numbers than their . . .
    The octane number of fuels are based on a set of primary reference fuels, which are mixtures of iso -octane and n -heptane Now iso -octane being branched alkane has very less tendency to react and given ON=100 and n -heptane reacts easily and given ON=0 However n -octane that is the corresponding linear isomer of iso -octane has an ON<0 Now why does branching in a alkanes reduce its reactivity?
  • Effect of temperature on Hydrogen Bonding? - Chemistry Stack Exchange
    We had this question in a test and I am not sure of the answer Q Temperature changes don't effect the extent of inter and intra molecular hydrogen bonding State true or false I think that rais
  • organic chemistry - What happens to the t-butyl cation in the TFA . . .
    According to a post-doc colleague, step no 4 IS the final state of the molecules in the solution (i e t-butyl can exist in the solution as a cation), but if water will be added to the solution, then the t-butyl cation will take an OH group and the TFA will become protonated In case anyone was wondering
  • inorganic chemistry - Why does magnesium hydroxide solution solidify . . .
    Intense homogenization separates many layers, but they eventually come together again by gravitational settling, perhaps even reforming crystals Magnesium hydroxide is prepared from seawater by precipitation with NaOH, over a period of settling for many hours; some new crystallization can be observed by x-ray diffraction (Ref 2)
  • thermodynamics - Why are hydrogenation reactions exothermic . . .
    I learned that all reactions that yield hydrogen are endothermic (such has reforming) and reactions that use up hydrogen are exothermic (FCC cracking, hydrogenation, etc )
  • intermolecular forces - Is a temperature decrease required for hydrogen . . .
    As I understand it, increasing the temperature of water causes hydrogen bonds to break Does this mean that a decrease in temperature is required for the formation of those hydrogen bonds?
  • What happens to the argon in the Haber-Bosch process?
    The steam reforming reaction uses an enormous amount of heat, some of which can be supplied by combustion of process air to generate nitrogen: (Air) + CH4 --> CO2 + 2 H2O + trace argon + x N2 (x = 8 approx) However there is insufficient heat from the partial combustion of air to generate all the hydrogen needed to consume the nitrogen produced
