A hybrid deep learning framework driven by data and reaction mechanism
for predicting glycolic acid production
Abstract
Selective oxidation at low temperatures without alkali of biomassis a
promising and sustainable avenue to manufacture glycolic acid (GA), a
biodegradable functional material to protect the environment. However,
producing glycolic acid with high selectivity and yield using the
traditional research and development approach is time-consuming and
labor-intensive. To this context, a hybrid deep learning framework
driven by data and reaction mechanisms for predicting sustainable
glycolic acid production was proposed, considering the lack of related
reaction mechanisms in the machine learning algorithms. Results showed
that the fully connected residual network exhibited superior performance
(average R2=0.98) for the multi-task prediction of conversion rate, GA,
and by-product yields, therefore employed for the following super
parameters optimization by the genetic algorithm. The L further
identifies that using the optimized operating parameters, the fossil
energy demand and greenhouse emissions have decreased by 2.96% and
3.00%, respectively.
