摘要

Crude oil separation

via

micropores in microporous polymer membranes is illustrated: selective acquisition of lighter compounds from actual crude oil.

Abstract

Crude oil has long been the "black gold" of the global economy

and its fractionation relies on thermal distillation

a highly energy-intensive process. In contrast

crude oil fractionation

via

membrane separation can operate under mild conditions

avoiding phase transitions

and thereby substantially reducing the energy consumption associated with thermal separation processes. Numerous microporous polymer membranes have been developed to target the fractionation of oil mixtures through precise molecular design and structural modulation for the selective separation of hydrocarbon compounds. However

the intrinsic trade-off between permeance and selectivity remains a core bottleneck limiting their advancement. Herein

we summarize the synthetic strategies for microporous polymer membranes

focusing on tailored pore structures

anti-swelling capabilities

and selective transport of hydrocarbon compounds across these membranes. The performance of representative materials for practical crude oil fractionation was also highlighted. We also outline critical unresolved challenges

including cost-efficient large-scale fabrication

long-term stability under harsh crude oil environments

and further optimization of

the permeance-selectivity balance

issues that must be addressed to promote the deployment of microporous polymer membranes.
