Abstract

The invention relates to a biodiesel pour point depressant composition as well as preparation and application thereof. The pour point depressant composition is prepared from the following components in percentage by weight: 40 to 60% of polytetradecyl methacrylate-acrylamide, 10 to 30% of Tween 60, 10 to 20% of dibutyl phthalate and 10 to 30 percent of polypropylene glycol. The growth and aggregation of crystals can be effectively inhibited by changing the crystallization behavior of biodiesel by the biodiesel pour point depressant composition, and the low-temperature performance of the biodiesel is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of diesel oil pour point depressant, and relates to a biodiesel pour point depressant composition and its preparation and application. Background technique [0002] Biodiesel is a biomass fuel produced from unprocessed or used vegetable oils and animal fats through different chemical reactions. Compared with ordinary petrochemical diesel, biodiesel has many advantages. For example, the raw material for preparing biodiesel is renewable raw material oil, which can effectively alleviate the oil crisis; at the same time, it has good degradability, non-toxicity, and contains sulfur after combustion. The amount is low, which is an environmentally friendly energy source. However, because biodiesel is easy to crystallize and block pipelines under low temperature conditions, it will affect the normal operation of the engine and reduce the practicability in cold weather conditions. Therefore, in the application of b...
