Abstract: The present invention relates to a process for the conversion of a low molecular weight polymeric byproduct obtained during production of high density polyethylene (HDPE), commonly known as low polymer wax (LPW) or polymer mud, into different products like different grades of paraffin wax, microcrystalline wax, lube and grease base stocks by a process comprising of thermal treatment in an inert atmosphere in the presence of organic peroxides or hydroperoxides and metal oxides. The end product depends upon the suitable selection of various process parameters like type of peroxides or hydroperoxides, metal oxides, temperature and duration of reaction.

Abstract: The present invention describes a process for converting high free fatty acid containing feed stocks (FFA 20-85%) like palm fatty acid distillate (PFAD), restaurant grease, waste cooking oil, Soya deodistillate, acid oil, jatropha curcas oil, mohua oil etc. to biodiesel, which involves esterification of FFA containing oil with lower alcohols like methanol, ethanol, propanol etc. in presence of macro reticular and gel type acidic heterogenous resin as catalyst to bring down acid value in the range of 1-2 mgKOH/g followed by transesterification in presence of homogeneous basic catalyst metal oxides, hydroxides and alkoxides like sodium hydroxide, potassium hydroxide, sodium methoxide, potassium methoxide etc. and separation of biodiesel and glycerine.

Abstract: Fatty acid alkyl esters suitable for use as biodiesel are produced by a single step esterification of free fatty acids and transesterification of triglycerides from vegetable oils or animal fats or combinations thereof with a lower alcohol (e.g. methanol) in presence of alkyl Tin oxide as catalyst. The ester thus produced is purified by distillation, treatment with an adsorbent, washing with water or combination thereof to give esters suitable for use as biodiesel.
