Catalyst for kitchen waste and kitchen waste treatment method

Abstract

The invention relates to a catalyst for kitchen waste. The catalyst is prepared by the following method: fully mixing 15-95 parts by weight of aluminum oxide, 5-32 parts by weight of silicon dioxide,0.01-0.1 part by weight of titanium dioxide, 0.5-10 parts by weight of aluminum chloride, 10-30 parts by weight of zinc oxide, 5-13 parts by weight of water and 3-10 parts by weight of high clay; calcining for 2 to 4 hours in a reducing atmosphere at 200 to 400 DEG C; and cooling, crushing and ball-milling until the specific surface area is 100-400 m < 2 > / g, the pore volume is 0.23-0.50 cm < 2 > / g and the average particle size is less than 200 meshes to obtain the catalyst for kitchen waste. The invention also relates to a kitchen waste treatment method. According to the invention, garbage classification is realized; illegal cooking oil is separated from the kitchen waste; the method comprises the following steps: synthesizing a solid catalyst, introducing illegal cooking oil separated from kitchen waste on site into a high-temperature pressure-resistant reaction kettle by using an electric heating device, a pressure-resistant device, a matched high-vacuum pump and a segmented heatingdevice by using the solid catalyst, and cracking the illegal cooking oil into bio-gasoline and biodiesel.

Description

technical field [0001] The invention relates to a catalyst for kitchen waste and a treatment method for kitchen waste. Background technique [0002] With the rapid development of my country's economy, the output of kitchen waste is increasing, and the resulting phenomenon of "kitchen waste oil" and "shui pig" seriously endanger people's life and health. Food waste disposal has become the most serious social and primary problem. Kitchen waste, commonly known as swill, also known as swill and swill, is the domestic waste formed by residents in the process of daily consumption. It is easy to rot and deteriorate, emits stench, and spreads bacteria and viruses. The main components of food waste include rice and flour food. Residues, vegetables, animal and vegetable oils, meat and bones, etc.; in terms of chemical composition, there are starch, cellulose, protein, lipids, and inorganic salts. [0003] At present, there is a single treatment method for food waste, such as compost...

Problems solved by technology

[0003]At present, there is a single treatment method for food waste, such as composting, anaerobic fermentation to produce biogas, etc. difficulty

In addition, a large number of poultry and animal carcasses and discarded vegetables and leaves from farmers are randomly discarded in inappropriate places, such as streams and rivers, causing serious pollution to the air, water sources and soil environment, and laying a hidden crisis for the spread of diseases
