TL;DR: In this paper , the performance of diaminohexane modified graphene oxide (DAH-GO) and diaminooctane modified GGO (DAO-GO), synthesized and grafted with diaminoalkanes, was investigated against the corrosion of carbon steel in 15% HCl, utilizing the experimental weight loss and electrochemical measurement techniques.

Abstract: The special interest in ultra-low sulfur diesel (ULSD) is informed by the need to comply with the strict government policy on low sulfur content of transportation fuels. Better knowledge of different factors that concern deep desulfurization of fuels is important to achieve ultra-low sulfur fuels and cheaper way of producing ULSD. Both the capital and operating cost of the adsorptive desulfurization process is cheaper compare to the conventional hydroprocessing. The need to produce more volume of fuel such as diesel with very low sulfur content from low grade feed stocks like heavy oil and light cycle oil (LCO) in order to meet up with the global demand for sulfur-free fuels is pertinent. Several on-going researches are pointing to the use of adsorbents for removal of sulfur compounds from the hydrocarbon refining stream. In this chapter, varieties of carbon nanomaterials suitable for adsorptive desulfurization are discussed. The approach is feasible for commercial applications with any adsorbent of an adequate lifetime of activity as well as high capacity.

TL;DR: In this article , the synthesis of nanosized X-type hexagonal ferrites with high quality is reported using the auto-combustion sol-gel method using high quality.

TL;DR: In this paper, a density functional theory approach was adopted to assess the various possibilities of interaction between carbon tetrachloride (CCl4) and the functionalized activated carbon (AC) and found that the adsorption activity of AC was facilitated by the existence of carboxyl and hydroxyl functionalities on its surface.

TL;DR: In this article, the authors provide extensive and useful information regarding membrane fouling and types of fouling mechanisms and strategies for membrane cleaning, including chemical (acids, bases, chelating agents, oxidants, disinfectants, and surfactants), physical, and mechanical means with emphasis on the cleaning temperature and time.
