In the background of global energy/resources shortage

alternative energy and new chemical processes are proposed

which are

however

not quantitatively and comprehensively evaluated

neither for long-term effect on the industrial sector and resources supply chain

nor for social development and ecological environment.We review advances in modeling

simulation

optimization

and integration of resource/energy chemical processes in recent years.The objective is to provide industry and decision makers with profound understanding of co-benefits and unintended impacts of the large-scale deployment of various process technologies on environment and resources in a life cycle perspective.By establishing life cycle models from feedstock

production

market

to recycling

integrated approaches are explored to evaluate the efficiency and sustainability of alternative processes.Furthermore

these approaches aim to rationalize and optimize flow-sheeting

reduce investment and operating costs

raise efficiency and minimize environmental impacts. Coal gasification syngas centered energy/chemical product chains are taken as the base cases. Multi-dimensional "technical-economical-environmental-societal" models are built

simulated

and optimized. Mass and exergy flow diagram

life cycle inventory

sustainability indicators are established.Resource/energy utilization efficiency

environmental impact

and economic benefits are quantitatively evaluated.Finally

a platform to support the life cycle analysis and decision-making is constructed for process evaluation

integrated innovation and optimization of existing and potential alternative energy/chemical processes.
