Does Market Competition Reduce Corporate Environmental Investment? Evidence From China's Anti‐Monopoly Law

Business Strategy and the Environment, EarlyView.
ABSTRACT This study examines whether stronger competition supports or constrains corporate environmental responsibility, using China's 2008 Anti‐Monopoly Law as a quasi‐natural experiment. Applying a difference‐in‐differences design to Chinese A‐share listed firms in heavily polluting industries from 2006 to 2019, we find that firms with high ...

Methanol With Increased Water Content in Internal Combustion Engines

Chemie Ingenieur Technik, EarlyView.
This study investigates the potential to improve overall Well‐to‐Wheel efficiency by using low‐purity methanol from synthesis of hydrogen and furnace gas as CO2‐source. Combustion efficiency is comparable to pure methanol, while distillation energy could be saved.

Design and implementation of a 3D‐printed modular distillation tower for experimental teaching in chemical engineering

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Several authors have reported the disconnection between the skills, abilities, and attitudes of graduates from STEM careers with the current needs of the labour market. In science and engineering fields, research has found the need for interdisciplinary approaches that encourage meaningful learning.

Influence of initial binary mixture state of matter on heat costs at rectification

Тонкие химические технологии, 2014
Analysis of heat cost for rectification was performed taking into account the phase state of the original mixture. It was proved theoretically that increasing feed vapor fraction leads to decreasing energy consumption in conventional distillation process.
