Methanol as a fuel for internal combustion engines

Progress in Energy and Combustion Science, 2019
Transportation of people and goods largely relies on the use of fossil hydrocarbons, contributing to global warming and problems with local air quality. There are a number of alternatives to fossil fuels that can avoid a net carbon emission and can also ...

Selective conversion of CO2 and H2 into aromatics

Nature Communications, 2018
Selective conversion of CO2 and H2 into aromatics remains challenging due to the high unsaturation degree and complex structure of aromatics. Here the authors report a composite catalyst of ZnAlOx and H-ZSM-5 which promotes the formation of aromatics ...

Implications of a short carbon pulse on biofilm formation on mica schist in microcosms with deep crystalline bedrock groundwater

Frontiers in Microbiology, 2023
Microbial life in the deep subsurface occupies rock surfaces as attached communities and biofilms. Previously, epilithic Fennoscandian deep subsurface bacterial communities were shown to host genetic potential, especially for heterotrophy and sulfur ...

Understanding the antagonistic effect of methanol as a component in surrogate fuel models: A case study of methanol/n-heptane mixtures

, 2021
Methanol is a widely used engine fuel, blend component, and additive. However, no systematic auto-ignition data or laminar flame speed measurements are available for kinetic studies of the effect of methanol as a blending or additive component.

Influence of Glycerol on Methanol Fuel Characteristics and Engine Combustion Performance

Energies, 2022
Methanol derived from solar energy is a carbon-neutral alternative fuel for engines. The low viscosity of methanol is one of the problems that restrict its direct compression ignition application in engines.

Single-atom catalyst for high-performance methanol oxidation

Nature Communications, 2021
Single-atom catalysts have been widely investigated for several electrocatalytic reactions except electrochemical alcohol oxidation. Herein, we synthesize atomically dispersed platinum on ruthenium oxide (Pt1/RuO2) using a simple impregnation-adsorption ...
