Problems solved by technology

At present, there are many kinds of coal-saving agents in China, but most of them are solid, and it is difficult to attach to the surface of the sample, resulting in a greatly reduced catalytic effect.
[0003] In the prior art, biomass materials such as straw and rice husk powder are usually used as coal-saving agent materials. For example, the patent number is CN201510539506.4, and the patent name is a patent for a green and efficient coal-saving agent. Peat, catalysts, inorganic fillers, plant fibers, mixed solvents, tougheners, flame retardants, mica powder, diatomaceous earth, ceramic powder, n-butanol, film-forming aids, antifreeze, combustion aids, sulfur-fixing agents are The main raw material, but the normal cellulose-containing biomass is not easy to sulfonate, and the calorific value is also low, and the combustion-supporting and sulfur-fixing effect has certain limitations
[0004] In addition, furfural slag is a waste produced in the process of biomass hydrolysis, and its large accumulation will pollute the atmosphere, soil, and rivers

Embodiment 1

[0023] A modified furfural slag biomass coal-saving agent, comprising the following components in percentage by weight: 65 parts of modified furfural slag, 10 parts of activator, 15 parts of oxygen enhancer, 10 parts of water; the concentration of activator is 10 parts % cerium nitrate solution, the oxygen enhancer is 10% calcium percarbonate solution.

[0024] The preparation method of the modified furfural slag biomass coal-saving agent is as follows:

[0025] 1) Modification of furfural slag: 45 parts of sodium sulfite, 100 parts of furfural slag, 100 parts of water, stirred in a reactor, heated to 100° C., and kept for 2 hours for reaction. Filter after the reaction.

[0026] 2) Preparation of the coal-saving agent: Weigh the modified furfural slag, cerium nitrate, and calcium percarbonate according to the above ingredients, and stir evenly to obtain the modified furfural slag biomass coal-saving agent.

Embodiment 2

[0028] A high-efficiency, energy-saving, smoke-eliminating and coal-saving agent comprises the following components in weight percentage: 45% of modified furfural slag, 5% of active agent, 10% of oxygen-enhancing agent dimethyl carbonate, and 40% of water.

[0029] Its preparation method is:

[0030] 1) Modification of furfural slag: 35 parts of sodium sulfite, 100 parts of furfural slag, 100 parts of water, stirred in a reactor, heated to 90° C., and kept for 2 hours for reaction. Filter after the reaction.

[0031] 2) Preparation of coal-saving agent: According to the above formula, the modified furfural slag, cerium nitrate, and dimethyl carbonate were stirred evenly.

Abstract

The invention discloses a modified furfural residue biomass coal-saving agent. Modified furfural residues are taken as a main raw material and compounded with an active agent and an oxygen producer to obtain the biomass coal-saving agent, and the coal-saving agent has the effects of catalytic combustion and efficient sulfur fixation, and is simple to operate, low in cost and beneficial to industrial popularization.

Description

technical field [0001] The invention relates to a modified furfural slag biomass coal-saving agent, which belongs to the field of coal-burning additive products. Background technique [0002] my country is a big coal-producing country, but also a big coal-consuming country. Coal is still one of the main energy and chemical raw materials in my country, and it is also the most common energy material at present. Since the founding of the People's Republic of China, my country's coal consumption has continued to grow. It is estimated that by 2050, the proportion of coal in primary energy consumption will still be more than 50%. Therefore, coal will still be in a dominant position in my country's energy consumption field for a long period of time in the future. . However, the current continuous rise in coal prices has increased the cost burden of enterprises, and it is urgent to adopt some technical means to save coal and reduce costs. The environmental protection department ha...
