A race to zero - Assessing the position of heavy industry in a global net-zero CO2 emissions context

چکیده
In this study, we explore the decarbonisation pathways of four carbon and energy-intensive industries (respectively iron & steel, clinker cement, chemicals pulp paper) in context a global 2050 net-zero emissions objective using IMAGE integrated assessment model. We systematically test robustness model by studying its responses to different narratives across six world regions. The study underpins earlier conclusions literature on ‘residual emissions’ ‘hard-to-abate sectors’, such as persistence residual overall continued use fossil fuels heavy within (with paper sector an exception). However, under condition that net-negative are achieved power energy conversion sectors prior landmark, indirect emission removals can compensate for left industry sectors, rendering these ‘net-zero’ early 2040s. Full industrial (sub)sector(s) is found be possible, but only very specific likely outside timeline cement chemical sector. Subsequently, find patterns regionally specific, though, strategic considerations (narratives) did not substantially change models’ response before or after 2050. Important aspects (direct indirect) electrification steel sector, full dependency removal technologies closing material loops zero-carbon heating further research modelling efforts needed broader palette conceivable implications economy context.

This work describes two different configurations of syngas production processes using a combination of steam methane reforming (SMR) and dry reforming of methane (DRM). The ideal SMR+DRM process ensures the maximum product yield, the heat-integrated SMR+DRM process fulfills the maximum heat recovery, and the stand-alone SMR+DRM process effectively suppress net CO2 emissions. Through kinetic mod...

15 صفحه اولTHE ZERO-DIVISOR GRAPH OF A MODULE
Let R be a commutative ring with identity and M an R-module. In this paper, we associate a graph to M, sayΓ(RM), such that when M=R, Γ(RM) coincide with the zero-divisor graph of R. Many well-known results by D.F. Anderson and P.S. Livingston have been generalized for Γ(RM). We Will show that Γ(RM) is connected withdiam Γ(RM)≤ 3 and if Γ(RM) contains a cycle, then Γ(RM)≤4. We will also show tha...
