The use of a sucrose precursor to prepare a carbon membrane for the separation of hydrogen from methane

Abstract

Development of an easier and less time-consuming technique to fabricate carbon membranes for the separation of H2 and CH4 using sucrose precursor.

The Implementation of a Carbon Precursor to Produce ZSM-5 Membranes for the Separation of Isomers in the Pervaporation System

“…The trends in the Figure 6 indicate that the concentration of the sucrose precursor solution was related directly to the separation factor and related inversely to the overall flux. This was attributed to the formation of more structures 26 because the concentration of the precursor increased as the d -spacing values decreased gradually from 3.21 to 3.11 (Figure 7). The d -spacing values of the membranes prepared at different sucrose concentrations were estimated by Bragg’s formula, that is, d = λ/2 sin θ.…”

Sugar‐Derived Nanocrystalline Graphite Matrix C/C Composites with Excellent Ablative Resistance at 3000 °C

“…Compared with the forgoing natural carbon sources, sugar substances are inexhaustible and renewable raw materials, and they are widely available and since they can be refined from most plants in nature. [ 13 ] The combination of these merit has fueled, many attempts to extract carbon from sugars to produce carbon materials, including using their foaming mechanism to produce graphene for supercapacitor applications, [ 18–20 ] using the pore structure of sugars into carbon to sieve gases, [ 21,22 ] and preparing other structural and functional materials. [ 23,24 ] However, the above methods are not suitable for preparing carbon matrices in C/C composites, due to the fact that a dense carbon matrix is difficult to form within the carbon fiber perform.…”
