    Abstract This work studies the nonlinear equation that models the diffusion and reaction in porous catalysts, which is of great importance in chemical engineering. The proposal is to obtain an approximate analytical expression that adequately describes the phenomenon considered. In order to find such approximation, we propose to use Laplace transform homotopy perturbation method (LT-HPM). It is observed in this analysis that the proposed solution is compact and easy to evaluate and involves polynomial functions of only five terms, which is ideal for practical applications. We find that the square residual error (S.R.E) of our solutions is in the range [10E-18, 10E-6] and this requires only fourth order approximation of the proposed method.

    this work presents LT-HPM method, in order to find approximate solutions for the second order nonlinear ordinary differential equation, that models a relevant problem in chemical engineering with, mixed boundary conditions [41,42].

    Problems with boundary conditions on infinite intervals belong to problems on semi-infinite domains [29,40]; nevertheless, in this article we present a different approach to solve them.

    With the purpose to understand how HPM works, we will present the following nonlinear problem [17,18]

Problems like the one mentioned, give rise to the search of solutions to nonlinear differential equations but unfortunately, solving this kind of equations is a difficult task. As a matter of fact, most of the times, it can only be get an approximate solution to such problems.

      With this end, LT-HPM uses the same steps of basic HPM until (5); next it is applied LT on both sides of (5), to get

      the case where the reaction rate depends nonlinearly on concentration; in such a way that it is possible to envisage the system as a solid material with pores through which the reactants and products diffuse. For the sake of simplicity, the system is conceived as simple diffusion by employing an

      effective constant diffusion coefficient D .

      This article introduced LT-HPM in order to get handy

      accurate approximate solutions for the problem with mixed boundary conditions that describes the problem of the diffusion and reaction in porous catalysts. Such as it is explained in [1], the understanding of this process it turns out relevant for the chemical engineer due to its applications in the design and operation of catalytic reactors. It should be mentioned that this problem has been successfully attacked for several authors. Thus, [1] found an approximate solution for (23), by using the Adomian decomposition method for some values of n order and Thiele modulus m . Although Adomian is a powerful tool, the process of obtaining its polynomial solutions are not straightforward for practical

      It is clear from the above discussion that LT-HPM describes a highly accurate way for solving, the nonlinear problem (23). On the other hand, is worth to note that our proposed solutions (48), (49), (73), (74), (79) and (81) are short and simple polynomial functions, ideal for practical applications. In all the cases considered we keep the order of approximation as four. If more accuracy for solutions is even required, one can go on with higher orders in a straightforward fashion, following LT-HPM algorithm.

      s

      Our results y(x) , indicate the concentration under steady conditions. From definition of Thiele modulus m (21), we identify the quantity 1LKyn 1 as a characteristic property

      applications. On the other hand [44] showed the application

      of homotopy analysis method HAM, to get the approximate

      for reaction, and

      e

      D L as a characteristic property for

      solution of the nonlinear model (23), for the cases of

      n 0.5, 2, and 4, for several values of m . Although in general HAM is very accurate, its expressions use to be long and cumbersome, as to be used in practical applications thus,

      [44] proposed approximations of 6th, 15th, 20th, 35th, and

      50th order. What is more, [50] went beyond, this article showed that, this model is exactly solvable in terms of Gauss hypergeometric function. The main advantage of this paper is that the hypergeometric function is well known, although its study it is not elementary. [45] employed HAM to investigate in all detail the case n 1. The solutions obtained are very long, and correspond to 30 th and 50 th order approximations of HAM, even though this paper obtained multiple solutions for this case. Unlike of the above studies, the goal of this article is to show the manner of getting handy approximate solutions for nonlinear problems like (23), through the use of LT-HPM. In fact, Figure (1), Figure (2), and Figure (3) show the accuracy of LT-HPM for the problem under study.

      In more precise terms, Figure 1 compares the numerical

      diffusion [1,44]. Therefore, the bigger the value of m , the

      bigger in proportion the diffusion respect to reaction phenomena and viceversa. From values of S.R.E one deduce that LT-HPM is more accurate for the cases, where the diffusion is relatively less important than reaction for a given value of n , that is for small values of m . Figure 1, Figure 2, and Figure 3, explain the above, noting that the curves with larger value of m present a major curvature than those, with smaller values, and for the same reason, they are more complicated to model. The simplicity and accuracy of the proposed method indicates that, unlike other methods, our solutions keep the nature of the studied phenomena and on the other hand, the reliability of the obtained results for the initially unknown values of the concentration of the reactant A .

      Finally, future investigations of LT-HPM should follow the aim of [45], where the authors obtained multiple solutions of (23), for the case n= – 1.

      solution of (23) for cases study:

      n 2 ,

      m 0.3 and

      n 2 ,

      m 0.6

      and approximations (48) and (49). Although the

      mentioned figure, shows the high accuracy of the proposed solutions, it was verified by evaluating the square residual

      b

      error (S.R.E) of (48) and (49) given by

      R2 u(t) dt ,

      a

      where a and b are two values depending on the given problem, the residual is defined by

      R u(t ) L u(t ) N u(t ) f (t ) , and

      u(t)

      is an

      approximate solution to (3) [16]. The resulting values were

      approximations (48) and (49).

    3. CONCLUSION

    From this study we conclude that LT-HPM is a useful tool to get accurate and handy solutions for the considered

    problem, which describes the phenomenon of the diffusion and reaction in porous catalyst. One of the highlights of this work lies in the practical and precise solutions obtained by LT-HPM compared to other methods, like HAM and Adomian Decomposition Method. We emphasize that one advantage of LT-HPM is that it does not require to solve several recurrence differential equations like other perturbative methods. Finally it is clear that the proposed methodology can be applied equally to other nonlinear problems, especially to heat diffusion problems.
