Spongy porous carbon nanosheets obtained by one-step oxidation-activation of asphalt with KHCO activator: Application in the cathode of zinc storage devices.

Porous carbon (PC) is widely used in Zn-based electrochemical devices (e.g., zinc ion capacitors and zinc iodine batteries), whose synthesis by conventional methods often leads to severe corrosion and high energy consumption.

Synthesis Strategies and Applications for Pitch-Based Anode: From Industrial By-Products to Power Sources.

It is significant for saving energy to manufacture superb-property batteries. Carbon is one of the most competitive anode materials in batteries, but it is hard for commercial graphite anodes to meet the increasingly higher energy-storage requirements. Moreover, the price of other better-performing carbon materials (such as graphene) is much higher than graphite, which is not conducive to massive production.

Effect of hydrogen-rich gas from char gasification on rapid pyrolysis products of low rank coal in a downer pyrolyzer.

For guiding a novel integrated process of low-rank coal pyrolysis and gasification with char gasification gas as a heat carrier, this study investigated the effect of simulated coal gas from char gasification (SCGG) on rapid pyrolysis products of low rank coal from 550 to 700 °C in a downer pyrolyzer. Results indicated that the component of SCGG directly affected the distribution and composition of pyrolysis products. Compared with N, SCGG facilitated the formation of tar below 600 °C.

Carbon precursors in coal tar: Extraction and preparation of carbon materials.

Coke resources are abundantly available worldwide and are a large by-product of tar production. Moreover, their utilization presents a series of environmental pollution problems. Common technologies for coal tar production applications urgently need to be upgraded because coal tar is listed as a national hazardous waste.
