Problems solved by technology

There is a patent disclosing the production method of butanol gasoline for vehicles. The obtained fuel is environmentally friendly and has stable performance. However, almost all of them are finished gasoline, in which various additives (including MTBE, etc.) have been added. The emission reduction and pollution There is no significant improvement in emissions
Patent CN105132046A discloses an alcohol-hydrocarbon composite fuel for vehicles. When the alcohol-hydrocarbon fuel is used as a vehicle fuel, the vehicle needs to be equipped with a fuel quantity controller, and the horsepower is also slightly insufficient. This is difficult for most car owners to accept, so the limit Its wide application in the field of vehicle fuel

Embodiment 1

[0029] Take the production of cellulose butanol complex alcohol hydrocarbon fuel B10 100L as an example:

[0030] The rice straw is hydrolyzed to obtain a hydrolyzate. After the hydrolyzate is refined, high-temperature cooking and sterilized, Clostridium acetobutylicum is added for fermentation to obtain a fermentation liquid containing cellulose butanol, and then the fermentation liquid is distilled to obtain a purity of 99.0wt%. of cellulose butanol. The prepared cellulose butanol 10L, toluene and C 9 Add 30L of aromatics, 55L of naphtha, and 5L of isopentane in a volume ratio of 1:2 into a stainless steel stirring container in sequence, mix and stir for 3 hours, settle, filter, and seal for 36 hours to obtain cellulose butanol complex alcohols Fuel B10.

Embodiment 2

[0032] Take the production of cellulose butanol complex alcohol hydrocarbon fuel B20 100L as an example:

[0033] The hydrolyzed liquid is obtained by decomposing the stalks of wheat. After the hydrolyzed liquid is refined, high-temperature cooking and sterilized, Clostridium acetobutylicum is added for fermentation to obtain a fermented liquid containing cellulose butanol, and then the fermented liquid is distilled to obtain a purity of 99.0 wt% of cellulose butanol. The prepared cellulose butanol 20L, C 8 and C 9 Add 12L of aromatics, 60L of naphtha, and 8L of isopentane in a volume ratio of 1:2 into a stainless steel stirring container in sequence, mix and stir for 6 hours, settle, filter, and seal for 18 hours to obtain cellulose butanol complex alcohols Fuel B20.

Embodiment 3

[0035] Take the production of cellulose butanol complex alcohol hydrocarbon fuel B55 100L as an example:

[0036] Sawdust is hydrolyzed to obtain a hydrolyzate. After the hydrolyzate is refined, high-temperature cooking and sterilized, Clostridium acetobutylicum is added for fermentation to obtain a fermentation liquid containing cellulose butanol, and then the fermentation liquid is distilled to obtain a purity of 99.0wt % of cellulose butanol. The prepared cellulose butanol 55L, toluene, C 8 and C 9 30L of aromatics, 10L of naphtha, and 5L of isopentane mixed in a volume ratio of 2:1:1 were sequentially added to a stainless steel stirring container, mixed and stirred for 4 hours, precipitated, filtered, and sealed for 24 hours to obtain cellulose-butanol compound Alcohol fuel B55.

Abstract

The invention discloses cellulose butanol compound alcohol hydrocarbon fuel and a preparation method thereof, and relates to the technical field of biomass clean fuel. The cellulose butanol compound alcohol hydrocarbon fuel is prepared by the following steps: mixing and stirring the following raw materials in parts by volume: 10-60 parts of cellulose butanol, 10-30 mixed aromatic, 10-60 naphtha and 5-10 isopentane for 3-6 hours; and participating, filtering and hermetically storing the mixture for 18-36 hours. The prepared fuel can be widely applied to the field of automobile fuel, is proper in octane number and oxygen content, sufficient in combustion; the preparation technology is simple and environment-friendly; the problems of insufficient power and the like of methanol / ethanol gasoline and methanol / ethanol automobile fuel are solved. Meanwhile, cellulose butanol is prepared from cellulose materials as main raw materials, so that energy utilization of the straw and the like is achieved; a solid backing support is provided for development of biomass energy and regeneration of automobile alternative liquid fuel; and the cellulose butanol compound alcohol hydrocarbon fuel has good economical and environmental benefits and a wide application prospect.

Description

technical field [0001] The invention relates to the technical field of biomass clean fuels, in particular to a cellulose butanol composite alcohol hydrocarbon fuel and a preparation method thereof. Background technique [0002] With the acceleration of fossil energy consumption and the intensification of environmental pollution emissions, the development of biomass liquid fuels has become an important measure for many countries to improve energy security, reduce greenhouse gas emissions and address climate change. my country's "Renewable Energy Medium and Long-Term Development Plan" has determined the goal of renewable energy development in the next 15 years: by 2020, the proportion of renewable energy in the energy structure will reach 16%. As one of the main consumers of energy, vehicles have an urgent need for clean and renewable fuels. [0003] Cellulosic biomass is an excellent renewable energy source, which is renewable and rich in resources, including agricultural pr...
