  • Can nano-pour point depressants improve the low-temperature fluidity of crude oil?
  • Nano-Pour point depressants have great potential to improve the low-temperature fluidity of waxy crude oil. This Review reviews the recent research progress of nano-pour point depressants in the field of crude oil pour point reduction.
  • Why are depressants not used in crude oil?
  • The reduced efficacy of depressants in crude oils can be attributed to the propensity of asphaltenes and colloids in crude oils to aggregate and attach to waxes at low temperatures, which impedes wax crystallization.
  • Do Eva/SIO 2 nano-pour point depressants reduce viscosity?
  • Li et al. 109 prepared EVA/SiO 2 nano-pour point depressants and compared their viscosity-reducing effects on model oil and crude oil, and the mechanism of action of the EVA/SiO 2 nano-pour point depressants on model oils and crude oils is shown in Figure 10.
  • Can nanosubstrates improve a pour point depressant?
  • The incorporation of nanosubstrates has led to a notable enhancement in the mechanical properties and thermal stability of the pour point depressant, accompanied by a broader selectivity to crude oil, which is of practical significance for industrial applications.
  • What is a nano-pour point depressant?
  • These nanomaterials consist of a polymer matrix of inorganic nanoparticles, which are later organically modified by a polymer pour point depressant coated with nanoclay materials, such as polymethyl acrylate, ethylene–vinyl acetate copolymer, poly α-olefin, etc., to form nano-pour point depressants.
  • Can nanomontmorillonite be used as a pour point depressant?
  • Nanomontmorillonite (MMT), a naturally occurring nanomineral commonly used to improve the rheology of crude oil, has been the focus of research in the field of pour point depressants as a “general purpose material”. Due to its hydrophilic nature, nanomontmorillonite usually requires organic modification to become organic montmorillonite (OMMT).
