Abstract
Research on Wheat Straw Pulping with Ionic Liquid 1-Ethyl-3-Methylimidazole Bromide
Highlights
The conventional pulping process is an ordinary technique applied to non-wood fibre pulping processes.[1,2,3] This method is a waste of chemicals, causes higher energy loss and heavier pollution, and takes a long reaction time, has low pulp yield, and is expensive
In order to achieve the comprehensive utilization of lignin as well as to solve common issues of high temperature, high pressure, low pulp yield, and severe pollution in the traditional chemical pulping processes, ionic liquid is chosen as the digestion liquor or pretreatment agent, and is considered to be beneficial for the pulping process
The results show that the pulping process of wheat straw using
Summary
The conventional pulping process is an ordinary technique applied to non-wood fibre pulping processes.[1,2,3] This method is a waste of chemicals, causes higher energy loss and heavier pollution, and takes a long reaction time, has low pulp yield, and is expensive. According to the national standard GB/T 2679.5-1995/1989, the paper physical properties are tested by Swedish L&W company determinators of bursting strength, tearing strength and breaking length In these experiments, ethylenediamine copper(II) solution is adopted as a solvent to dissolve cellulose and the relative viscosity η is measured by the capillary viscometer. The liquid phase is transferred into a beaker, left to stand for a certain time until the sediment is dissolved out, followed by centrifugal separation These precipitates are first treated with alkaline solution, a separation process, and an acidic solution. The fibre structure and morphology characteristics of wheat straw can be observed by SEM scanning (EM-30, Beijing Kusaimu Scientific Instruments Marketing Center, China) as well as a Universal Research Microscope after ionic liquid cooking pulping
