The primary goal is to examine the influences of dusty liquid, binary chemical reaction and the Arrhenius activation energy on a quadratic coupled convective liquid motion around a cone in liquid hydrogen diffusion. Saffman's "dusty gas" model is used to describe the flow, which considers the discrete phase (particles) and the continuous phase (liquid) to be two continuous objects occupying the same space. Activation energies and binary chemical reactions are commonly used as control mechanisms for effective heating and cooling processes. We intend to use non-similar transformations to assess the current problem. The non-similar transformation is then used to turn the equations specifying the boundary constraints into dimensionless views. Quasi-linearization and implicit finite difference approximation techniques are used to solve the non-dimensional governing equations. The surface drag coefficient enhances with increasing velocity fluid interaction parameter and mass concentration parameter values. Further, growing values of the suction parameter, the liquid velocity and temperature drop in the liquid and dusty phases. The liquid temperature increases in the dusty phase, while it decreases in the fluid phase with increasing values of the temperature fluid parameter. The mass transport strength upsurges with the growing temperature difference ratio and chemical reaction parameter values. The following are the novelties of this work: double-diffusive quadratic combined convection flows around a cone, the impact of the Suction/Injection parameter on the flow features, the influence of dusty liquid flow over a cone, binary chemical reactions and Arrhenius activation energy are used to analyse the flow characteristics, and the effect of liquid hydrogen diffusing species. Many scholars have investigated dusty fluid flow with various physical phenomena, but none of the writers has investigated the impact of Activation energy on coupled convective dust fluid flow.
