Embodiment 1

[0018] Production of biodiesel. First prepare enough needed various materials, then by the composition formula provided by the present invention and its content (weight %) ratio, promptly agriculture, forestry waste 55, solvent 30, auxiliary agent 9.0, catalyzer 1.0, additive 5.0 weigh all Various materials are needed, use waste peanut shells or sawdust 550kg, the first operation of the equipment, solvent use 300kg refined anthracene oil, auxiliary agent is methanol 90kg, catalyst aluminum chloride 10kg, additive CWS 50kg; agricultural and forestry waste peanuts Hull or sawdust, first of all pretreatment, after the waste is naturally dried, it is crushed to a particle size of ≤6cm, then transferred to the greenhouse for drying, at a room temperature of 100°C, dried for 24 hours, and the moisture content is ≤4%, and then it should be subjected to high-performance The pulverizer is crushed, the particle size is 60 mesh, and the particle size after entering the grinder is 120 mes...

Embodiment 2

[0021] Prepare the required raw materials to produce biodiesel. According to the component weight (%) ratio that the present invention provides: agriculture, forestry waste 50, solvent 30, auxiliary agent 9, catalyzer 1, additive 10, weigh various materials, waste adopts cottonseed hull or treetop 500kg, helps The solvent is 90kg of methanol, the catalyst is 10kg of aluminum chloride, the solvent is 300kg of distillate oil at 360-400℃ for recycling, and the additive is 100kg of coal water slurry; after pretreatment, the waste is transferred to the agitator together with the solvent, additive and catalyst , stirred for 10 minutes, fully stirred evenly and then transferred to the reaction process. First, the coal-water slurry was input into the reactor with a high-pressure pump, and then the uniformly stirred waste and all materials were input into the reactor; the reaction process was heated to 280 ° C, Reaction pressure 15MPa, reaction time 110 minutes; Other each operation an...

Embodiment 3

[0023] According to the component formulation and the weight (%) ratio provided by the invention, the raw materials are prepared to produce the biodiesel.

[0024] According to the component formula (weight %) ratio, agriculture, forestry waste 45, solvent 30, auxiliary agent 9, catalyst 1, coal water slurry 15; Weigh each material, get corncob or branch 450kg, auxiliary agent cetyl alcohol 90kg, catalyst aluminum chloride 10kg, coal water slurry 150kg, solvent 300kg, take the distillate oil from the distillation process at 360-400°C for recycling; after various materials are pretreated, waste, solvent, additives, and catalysts can be put into Fully stir in the agitator, and the stirring time is 15 minutes; before transferring to the reaction process, the coal-water slurry should be input into the reactor with a high-pressure pump, and then the fully stirred waste and its mixture should be input into the reactor; The temperature was 300° C., the reaction pressure was 16 MPa, a...

Abstract

The invention provides a technological method for preparing biodiesel by using agricultural and forestal waste, and relates to the field of energy. The invention provides a new method for producing the biodiesel aiming at the defects that the biodiesel research is complicated in technology, high in cost, expensive in manufacturing cost, and the like. The method comprises multiple processes, i.e., natural drying, crushing, stirring, reacting and distilling; the biodiesel is characterized by being prepared according to the following component formula by weight percent: 55-35% of agricultural and forestal waste, 30% of a solvent, 9% of an auxiliary agent, 1% of a catalyst and 5-25% of an additive; the agricultural and forestal waste as well as tree branches and leaves are taken as raw materials; the agricultural and forestal waste comprises one or more of rice straw, cotton seed hull and the like; refined anthracene oil is taken as the solvent, methyl alcohol is taken as the auxiliary agent, aluminum chloride is taken as the catalyst, and coal water slurry is taken as the additive; the biodiesel is prepared by stirring the needed materials, carrying out a reaction, and distilling. After being tried in an agricultural vehicle on the road, the biodiesel is proved to have a good effect, thus being quite popular with users.

Description

technical field [0001] The invention relates to the field of energy, in particular to a process for preparing biodiesel from agricultural and forestry waste. Background technique [0002] In today's energy-constrained world, biodiesel is recognized as the most promising renewable green energy in the world, so it has been valued by people from all walks of life. Although the production methods of biodiesel are different, the raw materials used are rapeseed oil, soybean oil and other oil plants, forest trees, and fruit trees, all of which have many shortcomings such as poor raw material sources, high cost, high cost, and large investment, making it difficult to popularize and apply . Contents of the invention [0003] The purpose of the present invention is to invent a new method for producing fuel oil from agricultural and forestry wastes in view of the many problems in the development of biodiesel in the world today, using traditional common petrochemical equipment, using...
