Abstract
The present invention relates to energy source technology, and is especially process of preparing diesel oil substitute with domestic garbage and coal. The present invention features that the material consists of domestic garbage 25-45 wt%, coal 15-35 wt%, solvent 30 wt%, assistant 5 wt% and catalyst 5 wt%. The coal is lignite, subbituminous coal, oil shale or turf; the solvent is anthracene oil in the initial operation stage and the 340-380 deg.c distillate oil after the equipment is in continuous operation; the assistant is methanol and the catalyst is industrial hydrochloric acid. Pre-treated garbage and coal as well as other materials are first mixed through stirring for 10-15 min, then reacted at 340-460 deg.c and 5.5-7.5 MPa for 30-70 min and finally distilled to obtain the 340 deg.c below distillate oil as the coarse diesel oil. The coarse diesel oil is blended with amyl nitrate to obtain the diesel oil substitute.
Description
Technical field
The present invention relates to energy field, is to utilize life of urban resident rubbish and low grade coal to produce a kind of novel method of substitute diesel for raw material specifically.
Background technology
Along with improving constantly of living standards of the people, domestic refuse quantity is doubled and redoubled, and environmental pollution is on the rise.At present, developed country adopts burning method to handle domestic refuse, the expense of founding the factory and running cost costliness; And when the refuse thermal value that is burned is lower than 3.35MJ/kg, also require to add ignition dope.China handles domestic refuse and adopts landfill method more than 95%, and this method causes the wasting of resources, can cause secondary pollution to surrounding environment, and simultaneously, the land occupation area is bigger; Present situation for a change, China also begins to adopt incineration technology, still, produces dioxin in the burning process, and its toxicity is 100 times of potassium cyanide, and is bigger approximately 900 times than arsenic toxicity, is that a kind of toxicity is extremely strong, and the carcinogenic substance that is difficult to decompose.
Summary of the invention
The objective of the invention is to handle many serious problems that domestic refuse is brought to environment at the world today, invent a kind of novel method and handled domestic refuse, utilize depleted domestic refuse and low-grade coal to make main raw material, adopt conventional petrochemical equipment to produce substitute diesel, reach the stone of turning waste into wealth, improve urban environment, alleviate the energy-intensive present situation.
The method of utilizing domestic refuse and coal to produce substitute diesel is by the pretreatment process of rubbish and coal, broken bag, sorting, magnetic separation, mechanical sorting hold concurrently selection by winnowing, fragmentation, pulverizing process, and stir, react, distill, concoct, filter each operation and form, it is characterized in that:
A) component prescription and content thereof (weight %) ratio:
Rubbish: 45-25
Coal: 15-35
Solvent: 30
Auxiliary agent: 5
Catalyzer: 5;
B) coal is brown coal, sub-bituminous coal, oil shale, peat, wherein a kind of or its mixing made raw material;
C) rubbish is town dweller's domestic refuse;
D) solvent: during the device first operation, employing carbolineum is solvent, when moving continuously, utilizes distillation process 340-380 ℃ distillate to make solvent;
E) auxiliary agent is methyl alcohol or hexadecanol;
F) catalyzer is a technical hydrochloric acid;
G) processing method is that coal carries out pre-treatment, and at first through pulverizing, granularity is at 200 orders; The rubbish pretreatment process comprises broken bag, sorting, magnetic separation, removes metal object, masonry, glass inorganics, enters broken process again, granularity≤30mm; Rubbish and coal are standby after pre-treatment; Then, press technical recipe and content thereof (weight %) ratio, required material is injected in the agitator through pretreated rubbish and coal, solvent, auxiliary agent, catalyzer, fully stirred 10-15 minute, afterwards, change reaction process over to, heat to 340-460 ℃, pressure 5.5-7.5MPa, the reaction times is 30-70 minute; Then, enter distillation process and be heated to 380 ℃, substitute diesel is that to cut temperature be distillations before 340 ℃, and 340-380 ℃ distillations returns the agitating procedure circulation and makes solvent; Enter blending process at last, the detected result according to distilling the gas oil that produces adds the blending agents amyl nitrate at normal temperatures, when gas oil is identical with the ordinary diesel oil technical performance index, promptly stops to add blending agents, and the add-on of blending agents is 0.3-1.0%; When temperature of reaction was 370-400 ℃, reaction pressure was 6.0-7.0MPa, and the reaction times is 45-55 minute.
The domestic garbage component constitutes and content (weight %) ratio, as following table:
More than be the measurement result to the domestic garbage component in territory, five six administrative areas of the People's Republic of China, Shenyang City, the equal difference of component content of the domestic refuse of Anshan, Dalian, each city's plastic bag packaging of Changchun is little, can be as the raw material of producing substitute diesel.
Positively effect of the present invention is that raw material sources are easy to get, and a large amount of domestic refuses can turn waste into wealth, and product cost is low; Required equipment crusher, agitator, still kettle all are traditional general chemical equipment, and low, the cycle of investment of founding the factory is short, it is fast to go into operation, and can obtain economic benefit in a short time; Both can alleviate fuel oil shortage problem in short supply, can open up new way for treatment of urban garbage again.
