Problems solved by technology

Despite considerable potential, most technologies for fuel production from lignocellulosic matter and other unconventional materials are not cost-effective and / or do not provide fuel products of sufficient quality for commercialization
For example, current methods of producing biofuels from lignocellulosic matter typically require a series of complex and time-consuming steps to separate the substrate into its various components, and in many cases require the use of expensive hydrolytic enzymes and fermenting microorganisms
In addition to these disadvantages, currently available methods fail to utilize the vast majority of substrate material that is not converted to fuel and is wasted
Furthermore, current methods produce fuels with significantly higher oxygen content than conventional fuels, thus their energy density is lower and their weak stability makes processing difficult (e.g. storage, blending with conventional fuels, grade upgrading, etc.)

Abstract

The invention discloses a biomass fuel based on corn straw, and a preparation method and a preparation production line thereof; a formula of the biomass fuel is composed of the components by the weight percentage: 60-80% of the corn straw, 20-25% of soybean straw, 0.2-0.5% of an expanding agent, 2-3% of an adhesive, 1-3% of water and 1-5% of a ripening agent. Provided is the biomass fuel based on the corn straw and having the advantages of low production cost, environmental protection, high quality, high burning rate and convenient batch production. When the corn straw biomass fuel prepared through the process and the formula is burnt, the corn straw biomass fuel has no fumes when burning, has the burning efficiency of 96-98%, and has relatively strong firepower and relatively low production cost. Moreover, when the production line is adopted for preparing the corn straw biomass fuel, the production line has the advantages of small occupied places, relatively high production efficiency, low labor cost and better automated production effect, and further controls the cost of the biomass fuel.

Description

technical field [0001] The invention relates to the technical field of biomass fuel based on corn stalks, in particular to the biomass fuel based on corn stalks and its preparation method and production line. Background technique [0002] The global demand for energy continues to grow while conventional petroleum (such as oil, natural gas and liquefied natural gas) reserves are decreasing. Peak oil production due to dwindling oil reserves increases the likelihood of a global energy crisis, especially if energy demand continues to grow as expected. Consequently, more and more attention has been devoted to exploiting previously unconventional fuel resources (eg, heavy oil, oil sands, oil shale) and other non-fossil sources of energy (eg, lignocellulosic materials). A remarkably large amount of research in the field of "alternative" energy production has focused on the production of biofuels from lignocellulosic matter. This technology raises the prospect of switching to plen...
